The park is opened 24 hours with out any restrictions.

Situated in the northern end of Chiswick, west

London and 10km for the centre of London.

Location:

Local planning

Authorities:

Majority of the site lies in the Borough of

Hounslow, along the northern edge of the site lies

in the London Borough of Ealing.

Approximately 2.5Ha

The London Borough of Hounslow owns the

free for the whole site including the Entrance

Yard.

Since 1985, the Borough has granted a li-

cence to London Wildlife Trust to manage

the site.

Area:

Land ownership:

Status: Site of Metropolitan Importance for Nature

Conservation adopted in the L. B. Hounslow UDP (1996) and Ealing UDP (1995).

Boundary: The site is bounded along two sides by railway lines; the District line runs along the southern boundary,

whilst the North London Line (Silverlink) runs along the north-west side. Part of the north-eastern boundaryis made up by the entrance yard, which has a frontage onto Bollo Lane; the remainder of the north-eastern

boundary abuts onto commercial buildings and a scrap metal yard on Bollo Lane.

The north-west boundary has recently been re-aligned, following demolition of an old brick bridge over the

North London line

Location

fg.1

Gunnersbury Triangle Nature reserve is

a small area of semi-natural secondary

woodland about 10km from the centre

of London.

The majority of the woodland and

its associated wildlife have become

established by natural succession.

The London Wildlife Trust has

managed the site since 1985, underlicence from the landowners, the

London Borough of Hounslow, who

designated the site as a

formal Local Nature Reserve status

in 1987 (and the L. B. Ealing similarly

designated the section that lies within

Ealing in 1991).

But it is the presence of a number of

locally uncommon species, are that

the site is recognized as a Site of

Metropolitan Importance for Nature

Conservation.

Currently the site is regularly used byschool parties and is open to the public

a weekday and one weekend.

the reserve is run usually by one

seasonal warden and a volunteer, and

this is between May through to October

of each year due to the cut down of

funds.

whilst the overgrown junglequality

of this area is part of the its appeal,

tis has to be balanced against public

safety, where boughs of the willow over

hang the path.

Despite the reserve being opened 24

hours, the limited facilities on the site

suggests the reserve is not to be viewed

as a local park, however the reserve ac-

commodates a full day event when the

park warden is available.The facilities also act as a deterrent to

troublesome teenagers or rough sleepers

by positioning the chair far apart and

allow some of the facilities to be available

during the time the warden is managing

the park which is only two days during the

weekdays.

Approximately 80% of

the site is covered

by recent secondary,semi-natural woodland

and scrub; the remain-

ing 20% is made up of

rough neutral grass-

land, acidic grass-

land, ruderal com-

munities, wetland

vegetation and a pond.

These communities have

grown up largely by

natural succession,

since the abandonmentof allotments on the

site used in the Sec-

ond World War.

Although the site

contains no nationally

rare species, a number

of locally uncommon

species are present

Fig.4

The species are di-

vides into 6 differentcommunities:

Grasses, Sedges &

Rushes

Ferns and Fern Allies

Mosses

Fungi and Micro-fungi

LiverwortsLichens

These communities are

managed by the park

warden, who is on the

site from early spring

to early winter.

The seed source become

established into the

site from other local

park and gardens,such

as Kew gardens whichis to the south west

of the site.

The trainagle is also

know for as the best

sites in the former

Middlesex for ferns,

including broad buck-

ler-fern, male-fern

and uncommon species1

The London wildlife trust manage

the site as it is leased by the Bor-

ough of Hounslow (LBH). The roleof the nature reserve in the local

community has evolved of the yearsbut the reserve has aim to achieve

the three main objectives and aims

which are unchanged since the lastmanagement plan of 1989, as fol-

lows;

To recognise the site as1.

an important example of

naturally-colonised wood-

land in an urban area, support-ing a range of locally uncommon

species.Thisisreectedbothinthe decision of the Public Inquiry

in favour of nature conservation

and, more recently, in the sitesdesignation as a Site of Metro-

politan Importance for Nature

Conservation.

2. To be valued as a place

where local people canamble peacefully,

It plays a valuable role3.

in providing a local

service in environmental

education

Analysis of the three aims:

Ecological - to manage the

nature reserve to conserve its natu-

ral biodiversity, and to conserve its

matrix of woodland, wetland and

grassland habitats through appropri-ate management.

Educational - to provide an edu-

cation service for local schools, col-

leges and the wider community.

Community - to enable access for

the local community and to preservethe feeling of naturalness, and rural

quality of the site, which is a large

part of its appeal.

(Based on existing objectives andaims of Gunnersbury triangle man-

agement plan)

The above objectives are all to dif-ferent extent achieved, and are

managed to a workable standard,

however management of these aimsare not frequently and consistently

carried out.In the above statements there is nomention of how human interven-

tion may be managed at any level

both visitors and wardens. There isalso no mention of how the reserve

intents to improve its publicity ofthe reserve which would enable the

warden to extend their stay and thus

carry out small management activi-

ties such as path clearance to im-

prove the access for the local com-munity this could be expressed to

replace:Community -equal opportunity of

access to site for less able bodies

as well as mothers with children andthe elderly.

The site in its current state is unsuit-

able for the requirement of thesecategory of people.

The management plan also make no

mention of the management of thepond wildlife. This is a crucial point

as the pond life adds to the diversityand being the main activity of the

site, This objective could be express

as an extent to the Community aimas:

To maintain pond life through ap-propriate management plan and to

provide education of the diversity ofwildlife present.

Another crucial point the current

management has not mention is theprotection of the trees and the wild-

life in the site. Human induce effectssuch as trampling being the most

damaging impact.

The Objective could have outline as

follows

To manage the foot fall and poten-tial damage to tree by enable partial

interaction.

Site Description Of Pond

The pond was dug in 1986 as

an economical move to attract

more visiting schools to the

site as well as to diversify

the potential the site has for

wildlife habitat. Activities

such as pond dipping have proven

to be very popular.

The pool is fed from the

natural water table, with the

result that the water level

uctuates seasonally. Most of

the vegetation has colonised

naturally, although some plants

have been introduced .The water is about 1.3m deep at

its deepest point (the south-

east side), but much shallower

elsewhere. In general there is

a gentle slope from the margins

towards the island in the centre.

It has no liner, and relies on

the natural water table. Some

marginal and submerged plants

were introduced in the rst year

(including the yellow ag iris,

purple loosestrife, cuckoo ower

and brooklime) but a majority

of the vegetation has colonised

naturally. A boardwalk and pond

dipping platform were installed

in 1992 with the help of a grant

from Barclays Bank and English

Nature. Additional shallow bays

have been added to the original

pond at various stages.

The water often becomes covered with duck-

weed, which represents a signicant man-

agement issue. In the past the water fern,

Azolla, has also been a serious problem.

Owing to its woodland setting, the pond re-

ceives a great deal of willow down (from

willow catkins) and has a tendency to de-velop oily lms.

Current management plan of the pond area

The pond was made to provide a focus

for school parties. An island was

left to provide nesting habitat forwildfowl. Management has included

cutting back the willows on the

island (annually or every second

year) to control shading of the water

and provide dense nesting cover for

mallard. Overhanging trees have also

been cut back to improve light levels

and reduce leaf litter in the water. In

some years duckweed has been a severe

problem; this has been cleared by hand

netting. The pond oor was partially

de-silted, by hand digging, in winter1997-8. However, water level remained

low throughout 1999,

Objectives

To maintain the pond principally as1.

an educational resource, recognising

that it is also valued as a gathering

point and sitting out area by general

visitors.

To promote diversity of aquatic life.2.

To encourage a diversity of submerged3.

and marginal vegetation, minimising

dominance of excessively large areas

by invasive species.To control tendency to eutrophication4.

and silting up, which results from

willow catkins, leaves etc falling

into the water.

To maintain the pond in a visually5.

attractive condition as an important

landscape feature.

The site has a wealth

of wildlife and tree

species set along side

the urban fabric that

enclosing it .

The site is also

recognised as one

of the few areas of

naturally colonised

woodland within the

inner suburbs of West

London.

In terms of diversity

the site displays a

considerable variety

of species for its

size and location.

The reserve doessupport a number of

plant and bird species

that are uncommon in a

region (west London).

These include narrow-

leaved hawkweed,

prickly buckler fern

and crested buckler-

fern and amongst

the birds locally

uncommon nesting

species include

blackcap, sparrowhawk,

whitethroat and lesser

whitethroat.

Despite the rarity

and uniqueness of the

site, there are a

number of issues that

might build up to make

the site unmanageableif left in its current

state.

The site currently

feels over hang with

short and twisted tree

branches, blurred

footpaths, drowningpond life and an

uneasy feeling if

venturing alone.

The idea of achieving

natural wildness and

seclusion on the site

has some what been

achieved here and

this is one of the

unique factors that

differentiates this

site from others.

However the site

has issues of rough

sleepers who use the

sites as a enclave and

drug use. Although

this has not posed any

threats to visitors to

the site, the reserve

wardens often has toclean and maintain

the representation of

the reserve as a safe

space for the locally

community to visit.

The current

management plan iswell planned however

I feel as there is a

shortage of staff to

carry out the work and

the maintenance of the

tree and shrubs to be

poorly managed.

The main conict, held by the Society of

Gunnersbury Triangle to the proposed improvement

to the site may be the aesthetics of the reserve,

who fell alterations may change the characteristic

and uniqueness of the site Improvements such as the

access for the disabled and mothers with buggies as

well as improvements to managed the sprawl of weeds

would make the site more commercialised and nature

would seem like it is conned to allocated areas2.

The Society would want to keep the reserve to feel

PROPOSAL FOR A MANAGEMENT PLAN

AIM: To manage and promote the site as a regionally valuable nature reserve, whichwillbeofeducationalandcommunitybenet.

OBJECTIVE: THE SITE HAS A NUMBER OF ISSUES THAT NEEDS TO BE ADDRESSES THESE INCLUDED:

Improving The Pruning Of Trees And Shrubs1.

Management Of Visitor Foot Fall And Pressure2.

Making A Better Advertising Campaign Of The Site3.

PROPOSAL

1 Proposal : Improving The Pruning Of Trees And Shrubs

This is the a simple diagram of

pruning.

This should would benet the site by

reducing the dierent layers of shades

and allowing more light and air to

circulate in the site.

:Improving the pruning of trees and shrubs

The shrub and trees are slightly over grown in

the summers causing a overcast and a sense ofuneasy to venture alone.

Pruning of the trees and the shrubs is vitally

important to allow the diversity of species to

ourish.

Currently there is a carpet of ivy under

the Silver Birch woodland compartment, and

much more densely in the Willow woodland

compartment.

Proposal : Making A Better Adverising Campaign Of The Site

The reserve is well

advertised on the

internet search

engineer but these

are out date and xed

information of the

site. the site are

also not regularly

updated

A more immediate

information about

the site can be

advertised on the

sites visitors board

as well as the train

station where anaverage of +/-2000

people pass everyday

also writing into

schools to invite

individual parents or

the school for day

visits can be also

implemented.

To managed these site

would need regular

updates about changes

to the site as well

as open public

discussion on issues

this would greatly

help the social

awareness of the site

Professional and Public Participation

Management plans

being carried out on

site in August 2009

where the fences in

the entrance yard

and the woodland

scrub in the north

area were being

renewed. The fences

began to form

splitters since their

were last renewed

back in 2006.

Despite the large

number of coppices

silver birch trunks

lying around the site

these could not be

used because small

vertebrate species

have began to inhabit

it.

When the management
