A guide to assist in the ecologicalrestoration of Hamilton’s gully systems.
GULLYRESTORATION
GUIDE
The Gully Restoration Programme is a partnership between the Hamilton
City Council and the community. The aim is to raise awareness and
appreciation of Hamilton's gully systems and to encourage a sense of
community ownership of these valuable areas. The Gully Restoration Guide
has been developed to provide the information required to plan and
implement a successful gully restoration project.
AcknowledgementsThe guide was funded by the Hamilton City Council's SustainableEnvironment Team and developed by a working group comprisingrepresentatives from the Hamilton City Council, The University of Waikato,Environment Waikato and local experts. Information presented in the guidehas been sourced from individuals and organisations with expert localknowledge of gully environments and restoration methods.

Visitors to Hamilton, and many residents, may not be aware of theextensive gully systems that exist within the city. These gullies addanother dimension to the cityscape, providing green space forrecreation, visual relief from the urban environment, and habitats(places to live) for a wide range of wildlife. They are also a vital partof the city’s walkway and drainage systems.
There are a number of significant gully systems in Hamilton and theremains of others that were largely filled in before their protectionin 1987. However, thegullies today don’tlook how they didbefore Europeansettlement in the area.Over time, as the cityhas expanded, thegullies’ natural features have been degraded and a large proportionof their native flora and fauna (plants and animals) has been lost.
Many members of the community have recognised how importantgullies are in realising the vision of restoring indigenous biodiversityback to Hamilton. With approximately half of Hamilton’s gulliesowned privately, residents and community groups have a majorrole to play in helping bring back native vegetation and bird life tothe city. This guides’ objective is to help groups or individual membersof the community to restore Hamilton’s valuable gully assets andwill tell you how to:
1 INTRODUCTION
1. Make an accurate and useful assessment of the project site2. Develop a project management plan taking into account site specific information3. Access resources and additional expertise and knowledge4. Make decisions on how to organise and implement a successful restoration project
The Hamilton Ecological District is one of themost modified areas in New Zealand. Only asmuch as 1.6 % of the original vegetation remains.
(Leathwick et al., 1995)

The gulllies are the result of the undermining of a geological formationof sands, silt, peat and gravel known as the Hinuera formation (adeposit formed from the accumulation of volcanic material broughtdown by the Waikato River from the Taupo area). Around 15,000years ago, the Waikato River started to cut down through thismaterial to create its present channel and as it deepened, springswere exposed along the riverbanks. As water drained from thesurrounding land, these springs undermined the banks causing slipsand creating a network of streams draining into the Waikato River.This process was repeated again and again giving rise to erosionand the formation of the steep-sided and intricate network of gulliesthat adjoin the river today.
Hamilton's gullies are a key landscape and natural feature withinthe city. “They are estimated to occupy around 750 hectares or8% of the city area” (Downs et. al. 2000).

Hamilton’s gully systems have lots of important functions and values.They contain significant areas of native vegetation and provideimportant green pathways for wildlife. They are used for a varietyof outdoor activities and are important for their scenic values. Thegullies also have cultural significance for Waikato iwi and containheritage sites of historical and cultural importance. The gully streamsare an essential part of Hamilton’s drainage network, channellingwater from urban areas into the Waikato River. The quality of waterwithin these streams is particularly important to the health ofresidents, wildlife and the food chain.
In 1989 a “Gully Protection Zone” was established as part of thenew Hamilton City Council District Plan, providing rules to controldevelopment in and around gullies. These rules’ cover buildingand construction in and near gullies, earthworks, removal ofvegetation and channelling of storm water.The plan was reviewedagain in 1997 to reflect Council’s responsibilities under the ResourceManagement Act, 1991. This is now covered by an EnvironmentalProtection Overlay. Ask Hamilton City Council for a copy of theleaflet “Protecting Our Gullies”. Looking after the ecological functionsof the gully systems is now an important part of city planning.
Hamilton’s District Plan envisages a Green Network which linksthe city’s natural features into a continuous natural corridor and,over time, restores them. The idea of this green corridor is to increaseour urban biodiversity (the variety of life forms that exist in aparticular place) and to improve the natural environment thatsupports the city.
It is not easy to successfully look after and improve the gully systemduring rapid growth in the city. Providing rules through the DistrictPlan to control aspects of development around gullies is one method,but by itself won’t be enough. The Council and the communitymust use a range of other methods to help achieve these goals,such as:
1. Restoring and replanting gullies in conjunction with the Community Planting Programme 2. Providing information and education to increase public awareness and understanding of environmental issues
4
Gullies are the best kept ecological secret of Hamilton City. With appropriatemanagement it is possible to restore many of these habitats to a state thatwill provide ongoing protection for close analogues of original systems.
(Clarkson et al., 2000).
There are a number of initiatives undertaken in Hamilton to protectand enhance gullies. Hamilton City Council’s Gully ManagementPlan and Council’s Gully Restoration Programme are a couple ofways Council is working towards improving the city’s naturalenvironment. Other community initiatives such as the gully registerproject, aims to identify and monitor restorations taking place inthe city’s gullies and is an important part of measuring progresstowards restoring indigenous biodiversity back to Hamilton.As at October 2003 some 187 hectares were under restorationincluding 142 ha on public land and 45 ha on private land. Witheffort from the whole community, Hamilton City can continue todevelop and grow in harmony with its unique gully systems andother important natural features.
Restoring and replanting Hamilton’s gullies is a long term processthat will take many years to achieve. However, as many Hamiltonianshave already found, ecological restoration is an enjoyable pastime.There are a number of groups throughout the city already attemptingto repair our neglected gully systems. Working together, we canreally make a difference to Hamilton’s neglected treasures and theecology of our city.
In the words of some gully restorers;
‘Making good progress-the rubbish has been reduced and the firstplants are starting to grow’
‘The Manuka we planted the autumn before last have doubled insize!
‘Huge numbers of many other native plants seedlings are comingup naturally and weeds have almost ceased to be a problem’The other day I looked out over the gully and thought - Next yearthere’ll be tui in those trees!’
3. Controlling weeds and pests on Council land 4. Developing gully management plans 5. Funding the purchase of gullies as reserves

STEP ONE
Get a feel for the site and think about how you might like itto look and feel when it is finished.
Think about what types of work you might need to do in thegully to reach your goals.
Visit one of the gullies in the Hamilton area that have beenrestored for examples, ideas and inspiration. Look at the mapon page six of this guide for where to find a gully restorationwhich you can visit.
Who owns the gully? Is it on private land or is it owned bythe City Council? Talk to Council and find out what rules andregulations apply to this land and what your obligations are.Approach the owners of the property adjoining yours and seeif they would like to get involved in the project or will giveyou permission to work in their area.
Make sure that everyone who will be affected by the projectknows about what will be happening and has had a chanceto have their input.
Talk with residents living adjacent to the gully. They may liketo join in on the project and/or could contribute to the resourcesneeded.
- Getting started
9
Draw a sketch of the gully to use as a base plan. A ‘birds eye view’sketch will be useful when planning your restoration as you canrecord information on the diagram as you go along. Start with abasic layout showingboundaries, distances,streams and entrypoints to the site. Drawother features onto them a p a n d m a k edetailed notes of usefulinformation.
You may like to obtain a copy of an aerial photoof your gully that shows the gully boundarieson it. Contact Hamilton City Council (DesignServices) who will be happy to help you. A smallfee applies for this service.
There may be areas of your gully that have special featuresor values that you want to keep. Make a note of these on the sketchof your gully so that you can include them in yourdesign later on.
Identify which part of the gully you would like to start restoring first.
STEP TWO- Information gathering
Don’t bite off more than you can chew! Remember a small,well planned and cared for planting has the best chance ofsuccess. Extending the restoration area can be done later onwhen earlier stages of planting have become established andmore resources become available.
Other natural features such as streams and natural waterways,rock features, animal and insect habitats (old logs) may beworked into your design.
Weeds and native plants- there may be some bush remnantsin your gully. These should be identified and protected. It canbe difficult to distinguish between native plants and weeds.Use the plant identification tables in the back of the guide tohelp you identify the plants in your gully.
10
Do your restoration in small steps
Base plan
You may also find evidence of Maori or early Europeanoccupation, treasures that make your site special. If you comeacross something contact Hamilton City Council who canadvise you on how best to protect these items.
The type of soil present in your gully will determine howwell your plants grow, and whether or not they will survive throughdry or very wet periods. Knowing what types of soil you have inyour area will give you an indication of the stability of gully banksand will help you decide what plants to plant and where. Use the‘Soil Characterisation Guide’ in the Appendix to help you work outthe soil types in each area of the gully.
Mark on your gully sketch the site conditions in your projectarea. Make a note of:
1. Damp or swampy areas with high water tables (especially in winter)2. Dry spots (especially in summer)3. Areas that may be susceptible to frosts (open areas with no vegetative protection)4. Windy or sheltered regions5. Steep slopes that are prone to erosion6. Shady and sunny spaces

Example of a Gully Profile
This idealised gully profile shows the range of sites likelyto be encountered in gully restorations. A steep hillslopeand crest on the left runs into a footslope where materialfrom the hillslope has accumulated. The footslope adjoinsthe very wet backswamp where overflow from the stream istrapped by a raised levee. The right of this gully profileis a terrace peatland but in some gullies the terrace may bewell drained.
Make a comparison between your gully and this profile. Identifysimilar areas. The profile shows what native trees like to growin the different zones of the gully, information that you canrefer to in Step 5.

HAMILTON GULLIES:How they were
Gully floor (Sand/Silt/Gravel/Organic)
The poorly drained gully floors and theirassociated backswamps were dominatedby kahikatea, pukatea, swamp maire, andcabbage tree. Understorey and groundcoverspecies included mapou, fuchsia, pate, coprosmaand ferns.
Gully sides (Sand/Gravel)
The well drained and steep gully sides werecovered with forest dominated totara, matai,kowhai, kanuka and mahoe. The understoreyincluded shrubs of mapou and mingimingiand the ground was covered in a variety offerns. Slopes too steep for forest had herbaceousor shrubby vegetation. Clarkson and Clarkson, 2000

The design of your gully restoration plan will depend on the aim ofyour project — what you want the gully to look like, what it willbe used for and what you want the project to achieve. There aremany possible aims for your project, and you need to clearly definethese before you start.
1. Restoring former native vegetation2. Enhancing aesthetic value (making the place more beautiful)3. Providing habitat (places to live) and food for birds and other animals 4. Controlling erosion5. Improving privacy or creating views6. Creating an educational resource7. Security
Knowing what you hope to achieve is important as it will influencewhat types of trees and shrubs you should plant and where youshould position them.
New Zealand’s plants are part of our heritage and most of themare not found anywhere else in the world. They are what givesNew Zealand much of its distinctive character. Restoring gullysystems with native plants not only enhances a particular area butalso helps the species to survive. The ‘Native Plants for Gullies’table provides information on many native plants that are suitablefor gully planting in Hamilton.
The aims of your project could include:
STEP THREE- Defining your project goals
14
Hamilton’s gullies are already home to a number of birds, includingmorepork (ruru), kingfisher (kotare) , fantail (piwakawaka) and greywarbler (riroriro).
However, local groups have identified that a significant amount ofnew restoration is needed to bring back birds like the tui and kereruto Hamilton. Individual restoration projects throughout the city areimportant stepping stones for native birds.
Certain plants are particularly attractive to birds that may feed onnectar, fruit or insects. There are many native trees and shrubs thatcan be planted to provide a year round food supply, but you will needto select these carefully so that there are fruit and flowers at the righttimes. Fruit eating birds are attracted to groups of different fruitingplants rather than a single species. Planting the right selection of plantswill create an environment suitable for insects that will in turn attractinsect feeding birds. See the ‘Native Plants for Gullies’ table thatindicates which species are particularly attractive to birds. Clearlythe easiest way to ensure the return of native birds to your bit ofbush is to plant as wide a range of native plants as possible.
Many native plants offer protection on sites where there is risk oferosion. Plants protect the ground from the direct impact of therain, bind the soil together with their roots and remove excesswater from the ground. The ‘Native Plants for Gullies’ table showsnative species thought to provide stability against erosion.
Maintaining and screening views may be one consideration in thedevelopment of a restoration plan. The ‘Native Plants for Gullies’table provides information on what species to plant and where, tomeet your goals. Plants can be chosen based on ultimate height,trunk diameter, the ability to be pruned and density of foliage.
When clearing dense undergrowth and putting paths throughgullies, think about how this might affect security in yourneighbourhood. Keep clear lines of sight, minimise places wherepeople can hide and limit access to properties.
15
Your concept plan will be the document that all those involved inthe gully restoration will referto. It will be based on all theinformation that you havecollected about your site andwill show how your projectshould look when you havefinished.
It is a good idea to draw up your planon a large sheet of paper so that youcan show a lot of detail on it. Whenyou have finished the plan you may liketo laminate it, so that you can take itinto the gully when you are workingthere without it getting dirty or torn.
Use the base plan sketch of the gully that you drew in Step Two todraw up your concept plan.
If you need help to identify where drainage systems are in the gully,contact the Hamilton City Council for advice.
Design a broad overall vision for the gully but mark off the areathat you can afford to do. Once you know how many plants youwill need, clearly markoff the zone that youwill be starting onfirst.
Mark on the concept plan where you will be building paths orviewing areas, and the points of entry into the gully. This willinfluence what types of plants you grow around these areas. Also,be aware of any existing or future uses of the gully when you planpathways through the site.
STEP FOUR- Drawing a concept plan
Remember, it is best to start restoring onecorner of your site first rather than plant toosparsely over a larger area (but keep in minda broad vision for the whole site).
16
Clearly note on the plan features at the site that you want to keep.Old logs that might be a habitat for animals and insects, large treesand areas of native vegetation may have a place in your restorationproject. Noting them on your plan will show everyone working atthe site that these features shouldn’t be removed.
Mark clearly on your plan ‘view lines’ from properties adjacent tothe gully. Some residents may not want their view blocked by largetrees and some may prefer views framed by trees or denser vegetationfor privacy. This information will influence what trees and shrubsyou will be planting in certain areas.
Once the Concept plan is completed you will need to think about where you will source the plants for your restoration.
Concept plan
17
Planning what you are going to plant and where will depend onthe aims of your planting project and the needs of the plants (whatconditions they will grow best in). Visit one of the sites on page6&7 to see examples of native plant communities typical of HamiltonGullies. Hukanui School gully is a good example as there is a widerange of site types. Use natural succession as a guide for when tosuccessfully plant a given species. Plant communities change(succession) over time as late arriving species grow up in the shadeand shelter of the first stage, or pioneer plants.
Early succession (pioneer or early stage) species such as manukaand karamu grow well in the open and their fast growth suppressesweeds. However, because these pioneers are short lived they willeventually, after about 10 to 20 years, die back and let weedsre-invade unless the middle and late stage species are alreadyestablished. The middle and late stage species need less light thanthe early ones, and their juvenile stages are often frost sensitive,so they can be planted once you have established some initial cover.In most sites in Hamilton you need to hand plant these latersuccession species since we have lost both the seed source and thedispersal agent-large native birds such as the kereru (wood pigeon).
On well drained soils, initial plantings of kanuka, lacebark, totara,matai, wineberry, lancewood and kowhai need to be underplantedwith tawa, mahoe, hangehange, kawakawa and tanekaha andmapou . Planting them into light wells either opened up by handor as they form naturally, will increase their growth rates.On moister soils, karamu, manuka, swamp sedge (Carex secta),wheki and ribbonwood that were planted as pioneers should beenriched in gaps or by underplanting with pukatea, swamp maire,rimu, kiekie and swamp coprosma (Coprosma tenuicaulis). Hardybroad tolerance species such as kahikatea, cabbage tree and harakekeare usually planted with the pioneers.
STEP FIVE- What to plant, where?
18
The ‘Native Plants for Gullies’ table will help you find plants thatwill suit both your needs and the conditions at your site. Use theinformation that you collected in Step Two about site conditions(soil type, drainage, shade etc.) and your project goals from StepThree (erosion, views, bird life etc.) to select the right plants forthe right spot.
Once you have decided what plants are going where, draw themon to your Concept plan, showing the names of each plant in theposition that they will be planted. This will ensure that everyoneworking on the project will know where certain plants are supposedto go. This will also help you work out how many plants you aregoing to need overall and how much of the area you can affordto do at any one stage. As more resources become available youcan progress into other areas.
19
The Native Plants for Gullies section will show you what plants willgrow best in the early, middle or late stages of your planting. It willalso help you decide on which combinations of plants grow togetherso that you can reconstruct plant communities similar to thoseoriginally found in Hamilton gullies. There was a great variety ofspecies in the original plant communities so there is no single recipefor success.
Initially you will only need to budget for plants that will grow inthe early stages of the restoration. Middle or late plants can beplanted at a later stage as outlined above.
There are a few native plants that arepoisonous if eaten. Be aware of theseplants when using them in a restoration.All parts of rangiora and kowhai arepoisonous. For both of these plants seekmedical advice immediately. Do not inducevomiting or give fluids.
Think carefully about where different plants should go.Placing plants randomly with little thought to the finalappearance of the planting is unlikely to create a pleasingresult. Imagine how the tree or shrub might look when it ismature and how much space it is likely to take up. To ensureplant survival, match the right plant to its preferred site in thegully.
Plant in groups or clumps of the same species avoiding straightlines or rows. This will help the planting look more natural andallow the grouped trees to shelter and support one another.Planting in groups of the same species will also aid pollinationso that your plants will self seed and produce fruit and nectarfor birds. Some species need both male and female plants,and you cannot tell male and female seedlings apart. Having4 or 5 of one plant will increase your chances of ending upwith some of each. Check with your local nursery to find outwhich plants have both male and females.
Plant densely. On average you will need one plant per squaremetre. This will help to reduce weeds by shading them out,and will copy natural forest conditions. However, take intoaccount how large the plant will grow.
Leave openings for views and for safety. Create areas withviews framed by trees and shrubs. Make sure plants do nothang over walkways, blocking lines of sight and creating placeswhere people can hide.
Look for a balance in your plantings, with variations in plantheights, light and shade, shapes and textures.
Your planting programme should take into account the variousstages that occur throughout a restoration. Try and copy thenatural stages of growth in a forest and plant early speciesfirst. Leave spaces amidst your planting for later species thatwill need shade, shelter and protection from the cold. Preparea list of the different species you want to include in your gullyrestoration and mark them according to the stage at whichthey should be planted.
20
Getting the plants for your restoration may take some time, dependingon whether you are going to buy them or grow them yourself. Startplanning where you will get your plants from well before yourplanting date. Remember, plant in stages. Don’t attempt to plantall at once.
NOTE:When selecting plants for your restoration project, aim to use ‘eco-sourced’plants, (plants sourced locally from natural bush areas in the Waikato area).Planting native plants grown from material collected in this region will helpto retain the special natural character of the plant by avoiding cross-breedingwith foreign plants. These plants are well-adapted for the climate and soilsof this area and will generally do better and flower and fruit more. In general,large plants grown in the right sized pot will grow better as they are lesslikely to be smothered by weeds. Avoid large plants that have become rootbound in small pots.
Local nurseries may be able to provide you with some ‘eco-sourced’native plants, but may not have the full range that you require. Acontractual arrangement with a reliable nursery to collect localseed and grow the plants for you could be one way to obtain goodplants at a low cost. Linking up with other organisations interestedin re-vegetation may enable you to share the plants and the cost.If your property borders a Council owned gully and you wish tobe involved in planting the public area, the Council may be ableto provide you with plants and assistance.
Growing your own plants is a useful way of getting to know thembetter. When you collect seed and propagate your own nativeplants, costs are likely to be lower. Ideally, the best ‘eco-sourcing’of seed is from vegetation already existing in your gully. If therearen’t enough trees and shrubs in your gully providing seed,contact Hamilton City Council who will advise you on whereyou can collect seed and will give the permission to do so. Seethe ‘Seed Collection and Propagation of Native Plants’ tablein the Appendices for more information.
STEP SIX- Where to get your plants?
21
The success of a gully restoration is dependent on good sitepreparation. Weed control is essential for a successful restoration,as gully weeds will overwhelm young native plants. Remove weedsand deal with their seedling re-growth before doing planting as itis difficult to control weeds which are mixed up with your newplants.Your plants will grow faster if there is no competition fromweeds for light, soil nutrients and water, and where there is suitabledrainage. Weed control is also essential for natural regeneration(emergence of seedlings) of native plants.
Weeds are plants that are growing where they are not wanted.Many have been brought into New Zealand as garden plants andbecause of the different growing conditions in New Zealand, havebecome a problem by smothering or strangling plants and trees andreplacing the native vegetation. There are many different types ofweeds that might be present in your gully. The ‘Weed Identificationand Control Methods’ table in the appendices will help you identifywhat they are and give advice on the best method to remove them.
Having chosen and pegged off the part of your gully you wish torestore, and having identified the remnant native plants that needto be retained (p10 and ‘weed identification and control methodsp 51), the next step is weed destruction. The best methods dependon the weed size. Big trees such as pine, gum and wattle needfelling; an arborist may be required. Privet and willow can bemanaged more easily. Willow can regrow from cut off pieces so killby scarfing or drilling the trunk and inserting undiluted glyphosate.Other small trees can be cut off and the cut stump treated withherbicide. In general, total weed destruction is preferable to weedingaround your plantings, which can be time consuming.On steep banks, to keep the risk of erosion low, clear a small areaat one time, leaving the roots of dead weeds in to stabilise theground. Plant immediately and densely with your new natives.On sites where weeds have been sprayed with a non residualherbicide like glyphosate, you can plant through the natural mulchof dead weeds.
STEP SEVEN- Preparing your site for planting
22
Weed Control
Try to control weeds by physically removing them, even thoughit might take a little extra effort. Where possible, minimise theuse of chemical sprays for weed control, as some chemicals mayhave an impact upon the environment:
1. Hand pull or dig out small plants and their roots.
2. Large plants can be cut and their stumps painted with a chemical gel / paste.
3. Some plants can be mulched and composted, however there are weeds that will survive this process and will need to be landfilled, for example wandering jew.
4. The use of a non residual systemic herbicide has the advantages of a no withholding period before you plant, and of killing weed roots which may otherwise re-sprout.
5. When clearing vegetation from each planting position, chip off the surface vegetation in a 500mm circle with your spade. This will help prevent re-growth of weeds.
23
Herbicide versus physical control of weeds
Herbicides are useful if you have a large site or difficult to controlweeds. If this is necessary then try to use the ones which have thelowest toxicity rating and environmental impact necessary to controlthat particular weed. Try to use only as much spray as is required.Doing this will not only reduce environmental effects but will costyou less.
Cut and paint stumps of woody weeds where possible as thisuses fewer chemicals than spraying. There is a new herbicide gelthat can be applied directly to the cut stem or foliage, killing theweed without harming the surrounding environment.See the Weedbusters website at http://www.wedbusters.org.nzfor more information. Using a weedwiper or weed brush to applyherbicide minimizes spray drift and allows you to spot controlweeds.It is also recommended that an additive such as Codacide Oil orPulse is mixed with the spray. It acts as a penetrant and antidriftagent and enhances the rainfastness of the chemicals applied.
If you do need to spray individual planting sites, do so in a ‘Z’pattern rather than spraying in a circle. Circular spraying appliestoo much spray in the centre and the chemicals may affect yourplants. There will also be too little spray at the edge and weedswill rapidly take over.
Observe how heavy rain soaks or runs away at each of your plantingsites. You may need to improve the drainage by digging channelsto remove water.
In sites that are likely to be waterlogged in winter, diga small mound and plant into the top of it. Raising theplanting area in this way will let water drain from theplant’s roots and will increase the chances of survival.In heavy clay, dig the mound and place soil on top ofthe clay.
In dry areas, dig a small hollow so that water will collectin the base and keep the plant moist.
24
Herbicide use
Now that you have your site prepared and your plants are oldenough, you are ready to start planting.
Set the plants out in their positions (see your Planting Plan).Make sure they have been soaked in a bucket until the potstops bubbling and are not sitting in the sun.
Dig a large hole, deeper and wider than the root ball, so thatthe roots are not cramped. Loosen the soil at the bottom ofthe hole to make it easier for the roots to get started and tohelp drainage. If the plant is root bound, very gently teasethe roots out to help them to grow straight.
Put the plant in the hole about 10cm deeper than the finalposition you want and replace the soil around the roots. Ifadding fertiliser make sure it doesn’t touch the roots as it willburn them. Pull the plant up so that the top of the root ballis 2cm below the level of the soil. This will straighten anyroots that are twisted or swept up. Fill in the rest of the hole.
Gently firm the soil around the plant with your hands or soleof your foot and leave the soil on top light and loose. Leavea small depression around the base of the plant to trap water.Be careful not to over compact.
Water at the time of planting!
Surround with mulch to keep weeds out and to keep the soilmoist.
STEP EIGHT- Planting
25
Planting Method
Time of yearPlanting can be done at any time of the year as long as you haveaccess to a good water supply at your site. However, for dry sites(gully bank tops) planting is best done in late autumn to early springwhen the soil is damp. Gully floors are wet and cold (frosty) in thewinter, so this area is best planted during spring to autumn. Thesame applies to any other frost prone site, but you will need towater the plants throughout summer. Mulching will help plants tosurvive at any time of the year, especially on open sites.
Mulching will help to control weed growth, reduce moisture lossand add nutrients to the soil. Many materials can be used as mulchincluding (untreated) wood shavings or sawdust, compost, grassclippings, plant material, stones, wet newspaper and even old (non-synthetic) carpet. However, do not use mulch on wet sites oranywhere near water flow as it is likely to be washed away andcould cause stream blockages.
Your planting is more likely to be successful with strong andhealthy plants, correctly prepared sites, good planting techniquesand the right selection of plants for the area.
The right plant in the right site, at the right time equals success.Get advice from a professional if you are unsure.
Plant on a cool morning or an overcast day and avoid windydays. Soak plant in a bucket of water until rootball is thoroughlywet.
Don’t pull the plant out of the bag by its stem. Cut the bagor turn the plant upside down and carefully remove.
Plant in clumps so plants protect each other from wind, frostand drought
On hot and dry sites, mulch around plants to keep soil cool and moist.
Where severe frosts are likely, plant sensitive plants on northfacing gully sides or beneath trees.
At windy sites, shelter behind wind tolerant plants, stake orconstruct a windbreak.
26
Now that you have your plants in place, your work isn’t over yet!One of the most important stages in any restoration programmeis ongoing maintenance. This is essential to ensure that all yourplants survive and that your site doesn’t get taken over by weeds.Neglecting to look after your gully may mean that you will haveto start all over again, losing all the time and resources that youput into it in the first place.
The ongoing maintenance stage is also a good time to monitorany successes or failures that you may have encountered. Youcan use this information when you begin further zones in yourrestoration and it could save you time and money in the future.While you are maintaining your planting is a good time to startpropagating your own trees and shrubs for the next stage of yourrestoration.
Releasing (Weed control)Releasing is the removal of weeds from around planted treesand shrubs and is essential to ensure the survival of your plants.Use a tool such as a grubber or slasher for cutting back vegetation,or pull weeds by hand being careful not to damage the roots ofyour plants. In gullies where weeds such as Wandering Jew orJapanese Honeysuckle are a problem, releasing should be doneevery month during the growing season.
Weed matsOrganic weed mats, which support the soil’s natural processes,are a good way to stop weeds from taking over your site andfrom strangling your plants. Old (non-synthetic) carpet cut intosquares and placed around each tree is a great way of keepingthe weeds at bay and the carpet will break down over time.
STEP NINE- Establishment and ongoing maintenance
27
WateringMake sure your plants are kept watered until they are wellestablished and can look after themselves, especially throughoutthe summer months.
Protect from the windOn windy sites, tie young trees loosely to a stake for support with flexible ties that allow the plant room to grow. Place the stake so that it supports the plant from the prevailing wind direction, often a double stake is best. Drive in stakes before planting to avoid damaging roots.
MonitoringKeep a record of any plant losses and the reasons why you thinkthey may have died. Every gully is different and there may be some conditions in your gully that certain plants don’t like. Thisinformation will be useful when you move on to other areas.
Ongoing plantingReplace failed plants with suitable alternatives if necessary. Middleand late stage plants can be planted once your early plants arewell established and some canopy cover is achieved. This couldtake a couple of years from the time of your first planting. Oncethe canopy is established it will start to control the weeds soother slower growing species can be planted along with groundcovers and ferns. Seed collection and scattering at your restorationsite is a good method for enhancement after the first stages ofrestoration have been completed.
BiodiversityHamilton’s gully systems originally contained a wide diversity ofnative plants-at least 250 species! Our native birds require a widerange of year round food sources; seeds, nectar and insects, andwe can ensure their return by planting a wide range of nativespecies in our restorations.
28
Animal pestsPossums in particular can cause considerable damage to yourplants and along with rats, mice, stoats and weasels reduce thebreeding success of native birds by eating their eggs and fledglings.Control of animal pests in an urban setting needs special careand attention. There are potential hazards for domestic pets andyoung children. Cage trapping is the best option for possumsbut bait stations with poison can be safely used if they are placedwhere only the target pest can access them. Consult pest controlexperts before you start.
Measuring successThere are a number of ways that you can measure the successof your gully restoration. Indicators of success could include:
Make regular checks of your plants for signs of animal pests or weed invasionand deal with the problem.
Don’t dump garden waste into gullies as it may include plants or seed that mayspread and infest native plantings. The dumping of garden waste into gulliesis how many of Hamilton’s gullies have become overridden with weeds.
Keep your plants watered, especially over spring and summer.
Look out for your first naturally regenerating seedlings and make sure theydon’t get smothered by weeds.
Keep your cats in at night when birds are nesting or looking after young, toencourage the return of native birds to gullies.
Natural regeneration of plants and trees from seed droppedby vegetation that you have planted or that has been broughtinto the site by birds and wind
The amount of bird and animal life in the gully
The extent of weed populations
The extent of community ownership of the gully area andthe restoration project

Soil Characterisation Guide
There are a number of very different regions within a gully and each hasdifferent types of soils. Your gully may have some, or all of the regionsthat are shown on the following ‘Gully profile’, and include the hillslopeand crest, footslope, backswamp, levee and terrace. The major types ofsoils found in gullies can be divided into simple classifications, includingsand (ash), pumice soil, clay, organic material and peat. Recognising thesetypes of soils at your site will help you decide what plants will grow bestin the different areas.
The soils of the hillslope and crest are usually sandy and are very welldrained. Often in summer only plants that can withstand droughts willsurvive here in the early years of planting. Very little organic material isfound in this zone as it is usually washed down the slope. Depending onthe gradient of the gully side, these soils are often prone to erosion andthe right plants must be selected to retain site stability.
The footslope is a narrow zone with fertile soils and is often the best zonein the gully for planting and growing. This is commonly the site whereorganic material from the gully slopes has accumulated and has abundantnutrients for good plant growth. The footslope has good drainage whereit meets the hillslope and poorer drainage near the terrace peatland.
The backswamp is a very poorly drained area and at certain times of theyear may be covered in water. The soils of the backswamp are largelywaterlogged peat and only swamp plants are likely to grow in this area.
The levee is a slightly raised and better drained habitat adjoining thestream.
The terrace is a flat alluvial plain adjacent the stream. Some terracescomprise peatland which can be of considerable depth. Many plant speciesare not tolerant of peat soils and will not survive so identification of theseareas is very important. Other areas are well drained with silts and loamsand are much easier to restore.
The following section will help you identify what types of soil arepresent at your site. Once you know what soils you have in yourarea you can work out what trees and shrubs you can plant.
32
The water table will vary at each of the different regions of the gullyand will also fluctuate between winter and summer. Knowing whereyour water table is and how wet or dry the soil is will influence whatyou plant, where, and whether or not you will need to water certainareas over summer. See the soil profiles for an indication of where thewater table might be in the areas of your gully.

Native Plants for Gullies
Can be planted in the first stage of the restorationand will provide protection for the next stage. Theirfast growth suppresses weeds and they attract birdsto encourage natural seeding of other native species.
Middle and late plants need protection from frostand wind and can tolerate lower light levels thanearly plantings. Protection from early plantings willspeed up their growth.

Propagation from seed is the best method for propagating nativeplants since it preserves genetic variations within the species. Thefollowing overview will tell you how to go about growing your ownseeds and the table outlines the different techniques to use fordifferent species.
Seed Collection and Propagation ofNative Plants
Seeds should be eco sourced, i.e. collected from natural bush areasin the Hamilton Basin. If in doubt about a seed source, seek advice.Seeds should not be collected without the permission of thelandowner or controlling authority. A good source of seed is naturalbush areas in your local gully, failing this, contact Hamilton CityCouncil (Parks and Gardens) for advice on where to collect seeds.Suitable eco-sourced seeds may be available from Wayne Bennett(ph 824 7167) or Peter Morris (ph 829 5763).
Laying a sheet for a number of weeks beneath trees that are droppingseed is an effective and easy way to collect seeds from tall trees.Make sure the sheet isn’t waterproof so that seed do not sit in poolsof water. A piece of Windbreak fabric works well.
Before sowing or storing seed for sowing later, some seed mustbe cleaned to remove material such as fleshy fruit and seed husks.The following table identifies the best ways to clean seeds fromdifferent species and an explanation of abbreviations used is given:
FS= friction, sieveSFSD= soak, friction, sieve, dryFSS= friction, sand, sieve
Soak: Soak the seeds in water for 2-3 days.Friction: Rub the seeds together to break husks.Sieve: Sieve the seeds to remove any fleshy or dry material.Dry: Spread seeds in a warm place to dry to prevent fungal growth.Sand: Mixing with sand will help seperate sticky seeds.
52
Seed that has been collected and cleaned can be stored in dryconditions (airtight containers) at 4.5°C for future use.
Use clean plastic or wooden trays or pots that allow for drainage.Fill the container with seed raising mix and firm lightly. Spread seedevenly and not too densely on the surface of the mix. Cover witha fine layer of pumice sand. Fine seeds will scatter more easily ifmixed with sand. Water well using a spray bottle or a watering canand cover the container with glass or enclose in a plastic bag toreduce moisture loss. Place in a warm location sheltered from windand strong sunlight. Keep the seed mix moist and ventilated, andremove the cover once germination begins.
When the seedlings are a few centimetres high transplant into smallpots or trays. Transplant again when the seedlings are larger andthe roots need more space. Larger pots or containers such as oldmilk cartons with holes for drainage are ideal. Plants are ready forplanting out once they reach at least 50cm in height. They willneed to be larger for more cold sensitive species.
Seed sowing tips
Mechanical: Breaking the seed coat with a knife.
Cold treatment: Placing moist seeds in the fridge (4°C) for a specified length of time. This simulates the
natural conditions over winter before seeds germinate in spring.
Treatment of seeds can speed up germination in some species. Themain types of seed treatments are:
Fresh is best. Seed should be sown as soon as possible aftercollection.Cleaning seed is not usually necessary unless you are going tostore it.Some seeds need to be soaked for several days to kill bugs. Suchspecies include swamp maire, tawa and lacebark.

To maintain the genetic diversity, plants used for restoration ofnatural vegetation should be propagated from seed, or from cuttingstaken from a large number of individual plants.

The following are weeds that you need toconsider when restoring a gully. Some areclassified pest plants under the BiosecurityAct and the Waikato Regional PestManagement Strategy. Information is givenfor both physical and chemical control ofthese weeds: for specific information onchemical application, including herbiciderates, visit the weed search atwww.weedbusters.org.nz. Where possibleremove weeds by physically removing thevegetation. If herbicide application is needed,choose a method that allows herbicide tobe directly applied to the weeds (e.g. cutand stump painting, boring holes in trunkand filling with herbicide), using overallspraying as a last resort when other optionsare not viable.
For further information contact your localBiosecurity Pest Plant Contractor withEnvironment Waikato (Ph: 0800BIOSECURITY).
