Fire Group Veg Groups Threatened Fauna Guidelines & Considerations A · 24 · 26 · 45 · 48 · 49 Barking owls require a home range between 600 – 1000 ha in size , where disturbance is limited to <25% of any of the vegetation group. Black-chinned honeyeaters do not persist in remnants less than 200 ha in size. Frequent and high intensity fires are undesirable. Vegetation corridors need to be protected in order to prevent declines in populations. Vegetation communities subjected to frequent fire are likely to be impacted in the long term as regeneration will be prevented. The felling of hollow bearing trees during 'mopping up' activities potentially decreases nest hollow availability. Least likely period of vulnerability to fire is between January and May. Where possible; · Fire should be contained to small areas. · Protect areas of habitat from fire, which consumes the canopy & or tall, large & hollow bearing trees. This is especially relevant in mature forests with limited disturbance. · Avoid felling large trees during incidents and planned fires (including mop up and maintenance). · Vegetation management guidelines should be managed at maximum fire intervals (>60 years apart). · Prescribed burns should be small. Long-term mosaic burns, where stands of shrubs are maintained, are more suitable in protecting species habitat and <25% of any individual vegetation community is targeted for treatment. B Streams & Riparian Areas These are areas effecting streams & dams or where species can be found within soil or under debris. Fire and soil disturbance can result in the loss of important species, which have significant roles within the ecology of the reserve and form a intricate part of the food chain. Increased erosion and run-off into streams and waterways, sedimentation and eutrophication, potentially impacts on these species. High intensity fire can remove riparian vegetation, reducing the filtering benefits of vegetation. Loss of nutrient from the site can effect water quality and may lead to algal blooms. Frequent prescribed burning is expected to have severe impacts on these habitats. Where possible; · Minimise the potential for frequent and or high intensity fires. · If prescribed burns are deemed necessary, keep fire at least 50m from streams & riparian areas. · Avoid the use of fire suppression chemicals within 50m of streams & riparian areas. · Avoid soil disturbance within 50m of streams & riparian areas. MAPS 1 & 2: FIRE HISTORY Ignitions There are no recorded ignitions within the reserve. Prescribed burns No prescribed burns have been implemented within the reserve by NPWS since the land was transferred in 2001. There have been no known prescribed burns applied during previous land management operations. Wildfire There are no records from the previous land management agency, either written or mapped, for the reserve. Neighbours can not recall observing fire within the reserve during their period of land management, where some have indicated the potential of >60 years without fire. Fire Frequency There are no indications that there has been a fire in the last 30-40 years, grass trees over 2 m tall show full skirts that have not been burnt for a long time. The frequency and interval between fire has important implications relevant to biodiversity and fire management. MAP 9: FUEL LANDSCAPE Recorded Fine Surface & Aerial Fuels (Recorded December 2005) T/ha Notes Minimum Fuels (including bark) 4.0 Vegetation Groups 45 – Moderate landscape fuels (NDVI) & high bushfire behaviour model. Maximum Fuels (including bark) 10.0 Vegetation Group 26 – Moderate landscape fuels (NDVI) & high bushfire behaviour model. The highest modelled fuels in this reserve do not exceed 15t/ha and occurs in <2 % of the reserve. Average Fuels (including bark) 7.0 Much of the reserve fuels modelled appears to fall within the 7 t/ha range. Management Notes The reserve fuel landscape modelling results provide a guide to potential available fuels across the landscape. Fuel landscape modelling is specific to this reserve and map view area. The information should not be used for comparing reserves across the broader area managed by the NPWS South West Slopes Region. High fuels recorded on this reserve were determined using the Overall Fuel Hazard Guide (3 rd Edition Dept of Natural Resources and Environment, 1999) at 4 sites ( n = 20). Conducted in December 2005, the highest fuel loads were 10 t/ha. The base line data for the fuel landscape map was extrapolated from NDVI (Vegetation Index) relationships from LANDSAT Imagery (2004) and visual fuel sampling data to calculate the potential vegetation density across the landscape. To improve the understanding of this relationship, the LANDSAT Imagery should be taken at a similar time as fuel assessments. Approximately 90% of the reserve fine surface fuels and aerial fuels measured between 2 to 5 t/ha. The fuel ratings become exaggerated when bark hazards are added during the visual assessment process. As the reserve has not been burnt for over 60 years, the fibrous stringy barks add significantly to the overall hazard. The high to very high bark hazard adds 2-5t/ha to each sample site. The data indicates, across the landscape, fuel loads generally conform to levels prescribed for strategic fuel management zones (8-15t/ha for 60-80% of zone). The sampled sites and modelled area indicate the Downfall Nature Reserve has a low to moderate bushfire risk. Four fuel monitoring sites, with photographic references, have been established in the reserve to monitor landscape fuel and vegetation conditions. These conditions and vegetation structure will change over time and the established fuel sites will, if monitored regularly, provide data to update fuel landscape maps and review fire risk and management options. MAP 8: BUSHFIRE MANAGEMENT ZONES Management Zone Definition Management Guidelines Asset (APZ) Life, property and commercial assets in high Bushfire Behaviour Potential risk areas on DEC estate. · Assets should be evaluated annually to measure potential hazards and or increased threats. · Works program to follow Risk Assessment (Life and Property) Guidelines. Fuel (FMA) Fuel Monitoring Areas are localities for monitoring fine surface fuel, grasses, shrubs, dead and down material and ecological health. · Monitor regularly to quantify changes in the fuel landscape, which may indicate an increase in risk. · Monitor to improve knowledge ecological responses and health and identify undesirable changes in vegetation communities. · Use areas to establish SFMZ’s where appropriate. Strategic (SFMZ) Strategic Fuel Management Zones are areas used to target ‘potential’ risks of high fuels, high fire intensity, increased rate of spread, spotting or to consolidate reserve APZ’s. The zone is not a commitment to execute prescribed burns in the target area, within the life of the plan. · The implementation of fuel management programs should comply with BFCC guidelines and should be conducted in areas identified in this strategy as a SFMZ. · Implementing prescribed burns or other vegetation manipulation program should only occur where more than 80% of the zone exceeds 15 t/ha (BFCC). · Any program must include monitoring before and after prescribed burns to determine effectiveness of the program on fuels and the ecological impacts. Heritage 1 (HMZ1) Areas of high priority natural and cultural conservation value. It identifies areas of ‘recorded’ cultural and natural assets. This zone is important for the protection of cultural heritage and the conservation of some species habitat to prevent declining numbers or extinctions. · Heritage areas should be assessed annually to determine potential hazard, threats to cultural heritage, and thresholds for TSC and vegetation communities. · Prescribed fire may be applied in these areas if appropriate for ecological purposes or protection of cultural heritage. · Implement recovery plan guidelines (where they exist). · Manage during incidents according to HMZ1 guidelines. Heritage 2 (HMZ2) This zone identifies areas of significance for natural and cultural features across the broader landscape. This generally means ‘parts of the reserve that have not been surveyed and or have no records of significant features or threatened species’. · These heritage zones should be monitored to determine threats to biodiversity and managed in accordance with conservation policy and principles. · Prescribed fire may be applied in these areas if appropriate for ecological purposes or protection of cultural heritage. · Manage during incidents according to HMZ2 guidelines. RESOURCE INFORMATON Downfall Nature Reserve (496 ha) was gazetted on 1 st January 2001. For the purposes of the Fire Management Strategy, Downfall Nature Reserve will be referred to as the “Reserve’, unless otherwise stated. The Reserve straddles a ridgeline that stretches from Humula to Tumbarumba. The reserve is approximately 26kms south-west of Batlow, NSW. The reserve is similar to Courabyra Nature Reserve, 16kms to the south south-west, being an island of native vegetation supporting an array of endangered species and habitat in a landscape dominated by pine plantations. Threatened species include squirrel gliders, brown tree creepers, diamond firetails, barking owls and turquoise parrots. Access to the west of the reserve is through private land, via Canaarvan Trail off Downfall Road or via State Forest trails to the south. There is no running water or dams within the reserve. Umbango Creek may not hold water during dry periods.

Other assets (including private property or other lands adjacent to the park) · Property assets may be damaged by fire escaping the park. · Vineyards, orchards and plantations may be affected by fire escaping the park · Vineyards and orchards may also be affected by smoke from fires. · Maintain access trails and firebreaks within the park that will assist in fire fighting efforts. · Participate in fire management proposals through RFS Zone Bush Fire Management Committee meetings. · During the fire season rapidly respond to all unplanned fires to minimise potential spread to private lands. · Vineyard and orchid neighbours should be consulted when developing prescribed burns to ensure commercial crops are not damaged by smoke. MAP 4: VEGETATION THRESHOLD ANALYSIS Threshold Vegetation Group % of Reserve Interpretation & Management Guidelines Overburnt N/A 0 If identified, two consecutive fires have been recorded too close together and the area is overburnt. · Additional fire in this area would lead to adverse fire regimes and may threaten community biodiversity. Vulnerable N/A 0 If identified, would be overburnt if the area burns before the end of 2006. · Fire should be avoided for this year and until another analysis of thresholds is modelled to reassess threats. Recently burnt N/A 0 If identified, the time since fire would be less than the threshold intervals. Fire this year would push this vegetation into the vulnerable class. · Fire should be avoided for this year, but could be assessed for proposed burning or other program in the future. Underburnt N/A 0 May require fire after 2006 for Asset protection, strategic or biodiversity reasons. · Planned fire may be introduced for fuel reduction burning for asset and strategic protection programs, ecological purposes and unplanned fire events may be allowed to burn if - The vegetation community demonstrates a loss of biodiversity - conditions are suitable - the intensity meets vegetation, flora and fauna community requirements - >50% of any vegetation community group in any threshold across the reserve is classed as Ok, Almost Underburnt and Underburnt. Almost Underburnt N/A 0 Planned fire may be introduced for fuel reduction burning for asset or strategic protection programs after 2006. · Unplanned fire events may be allowed to burn if - The vegetation community demonstrates a loss of biodiversity - conditions are suitable - the intensity meets vegetation, flora and fauna community requirements - >50% of any vegetation community group in any threshold across the reserve is classed as Ok, almost underburnt and underburnt. · This area will fall into the underburnt category by the end of 2007 if it remains unaffected by fire, but would fall into Recently Burnt if burnt in 2006. OK 24, 26, 45, 48, 49 100 Areas which thresholds have been assigned to, which don’t fall into one of the above categories. Fire is neither required or to be avoided. · Fire should only be applied in areas if a loss of biodiversity is demonstrated. · Where possible, >50% of any vegetation community group in any threshold across the reserve is classed as Ok, Almost Underburnt and Underburnt. Unknown/ No Regime Assigned N/A 0 The fire history is too short to determine whether it is underburnt or over burnt. Areas that do not have a threshold assigned to them or there is missing data, limiting the modelling capabilities in DEC GIS. Note: The threshold analysis is derived from vegetation community thresholds and recorded fire history (including fire frequency and intervals). All vegetation communities should be monitored and planned fire should only be applied if a loss of biodiversity is demonstrated. In the event of fire in this reserve, the analysis would have to be performed again to establish new threshold values.

Barking owls require a home range between 600 – 1000 ha in size , where disturbance is limited to <25%of any of the vegetation group. Black-chinned honeyeaters do not persist in remnants less than 200 ha insize. Frequent and high intensity fires are undesirable. Vegetation corridors need to be protected in orderto prevent declines in populations. Vegetation communities subjected to frequent fire are likely to beimpacted in the long term as regeneration will be prevented. The felling of hollow bearing trees during'mopping up' activities potentially decreases nest hollow availability. Least likely period of vulnerability tofire is between January and May.Where possible;· Fire should be contained to small areas.· Protect areas of habitat from fire, which consumes the canopy & or tall, large & hollow bearing trees.

This is especially relevant in mature forests with limited disturbance.· Avoid felling large trees during incidents and planned fires (including mop up and maintenance).· Vegetation management guidelines should be managed at maximum fire intervals (>60 years apart).· Prescribed burns should be small. Long-term mosaic burns, where stands of shrubs are maintained,

are more suitable in protecting species habitat and <25% of any individual vegetation community istargeted for treatment.

BStreams&RiparianAreas

These are areas effecting streams & dams or where species can be found within soil or under debris. Fireand soil disturbance can result in the loss of important species, which have significant roles within theecology of the reserve and form a intricate part of the food chain. Increased erosion and run-off intostreams and waterways, sedimentation and eutrophication, potentially impacts on these species. Highintensity fire can remove riparian vegetation, reducing the filtering benefits of vegetation. Loss of nutrientfrom the site can effect water quality and may lead to algal blooms. Frequent prescribed burning isexpected to have severe impacts on these habitats.Where possible;· Minimise the potential for frequent and or high intensity fires.· If prescribed burns are deemed necessary, keep fire at least 50m from streams & riparian areas.· Avoid the use of fire suppression chemicals within 50m of streams & riparian areas.· Avoid soil disturbance within 50m of streams & riparian areas.

MAPS 1 & 2: FIRE HISTORYIgnitions There are no recorded ignitions within the reserve.

Prescribedburns No prescribed burns have been implemented within the reserve by NPWS since the land was transferred in 2001.There have been no known prescribed burns applied during previous land management operations.

Wildfire There are no records from the previous land management agency, either written or mapped, for the reserve.Neighbours can not recall observing fire within the reserve during their period of land management, where somehave indicated the potential of >60 years without fire.

FireFrequencyThere are no indications that there has been a fire in the last 30-40 years, grass trees over 2 m tall show full skirtsthat have not been burnt for a long time. The frequency and interval between fire has important implicationsrelevant to biodiversity and fire management.

MAP 9: FUEL LANDSCAPERecorded Fine Surface & Aerial Fuels(Recorded December 2005) T/ha NotesMinimum Fuels (including bark) 4.0 Vegetation Groups 45 – Moderate landscape fuels (NDVI) & high bushfire

behaviour model.Maximum Fuels (including bark) 10.0 Vegetation Group 26 – Moderate landscape fuels (NDVI) & high bushfire

behaviour model. The highest modelled fuels in this reserve do notexceed 15t/ha and occurs in <2 % of the reserve.

Average Fuels (including bark) 7.0 Much of the reserve fuels modelled appears to fall within the 7 t/ha range.Management NotesThe reserve fuel landscape modelling results provide a guide to potential available fuels across the landscape. Fuel landscapemodelling is specific to this reserve and map view area. The information should not be used for comparing reserves across thebroader area managed by the NPWS South West Slopes Region. High fuels recorded on this reserve were determined using theOverall Fuel Hazard Guide (3rd Edition Dept of Natural Resources and Environment, 1999) at 4 sites ( n = 20). Conducted inDecember 2005, the highest fuel loads were 10 t/ha. The base line data for the fuel landscape map was extrapolated from NDVI(Vegetation Index) relationships from LANDSAT Imagery (2004) and visual fuel sampling data to calculate the potential vegetationdensity across the landscape. To improve the understanding of this relationship, the LANDSAT Imagery should be taken at a similartime as fuel assessments.Approximately 90% of the reserve fine surface fuels and aerial fuels measured between 2 to 5 t/ha. The fuel ratings becomeexaggerated when bark hazards are added during the visual assessment process. As the reserve has not been burnt for over 60years, the fibrous stringy barks add significantly to the overall hazard. The high to very high bark hazard adds 2-5t/ha to each samplesite. The data indicates, across the landscape, fuel loads generally conform to levels prescribed for strategic fuel managementzones (8-15t/ha for 60-80% of zone). The sampled sites and modelled area indicate the Downfall Nature Reserve has a low tomoderate bushfire risk.Four fuel monitoring sites, with photographic references, have been established in the reserve to monitor landscape fuel andvegetation conditions. These conditions and vegetation structure will change over time and the established fuel sites will, ifmonitored regularly, provide data to update fuel landscape maps and review fire risk and management options.

MAP 8: BUSHFIRE MANAGEMENT ZONESManagementZone Definition Management Guidelines

Asset(APZ)Life, property and commercial assets in highBushfire Behaviour Potential risk areas on DECestate.

· Assets should be evaluated annually to measure potentialhazards and or increased threats.

· Works program to follow Risk Assessment (Life andProperty) Guidelines.

Fuel(FMA)Fuel Monitoring Areas are localities formonitoring fine surface fuel, grasses, shrubs,dead and down material and ecological health.

· Monitor regularly to quantify changes in the fuel landscape,which may indicate an increase in risk.

· Monitor to improve knowledge ecological responses andhealth and identify undesirable changes in vegetationcommunities.

· Use areas to establish SFMZ’s where appropriate.

Strategic(SFMZ)

Strategic Fuel Management Zones are areasused to target ‘potential’ risks of high fuels,high fire intensity, increased rate of spread,spotting or to consolidate reserve APZ’s. Thezone is not a commitment to executeprescribed burns in the target area, within thelife of the plan.

· The implementation of fuel management programs shouldcomply with BFCC guidelines and should be conducted inareas identified in this strategy as a SFMZ.

· Implementing prescribed burns or other vegetationmanipulation program should only occur where more than80% of the zone exceeds 15 t/ha (BFCC).

· Any program must include monitoring before and afterprescribed burns to determine effectiveness of the programon fuels and the ecological impacts.

Heritage 1(HMZ1)

Areas of high priority natural and culturalconservation value. It identifies areas of‘recorded’ cultural and natural assets. Thiszone is important for the protection of culturalheritage and the conservation of some specieshabitat to prevent declining numbers orextinctions.

· Heritage areas should be assessed annually to determinepotential hazard, threats to cultural heritage, andthresholds for TSC and vegetation communities.

· Prescribed fire may be applied in these areas if appropriatefor ecological purposes or protection of cultural heritage.

· Implement recovery plan guidelines (where they exist).· Manage during incidents according to HMZ1 guidelines.

Heritage 2(HMZ2)This zone identifies areas of significance fornatural and cultural features across the broaderlandscape. This generally means ‘parts of thereserve that have not been surveyed and orhave no records of significant features orthreatened species’.

· These heritage zones should be monitored to determinethreats to biodiversity and managed in accordance withconservation policy and principles.

· Prescribed fire may be applied in these areas if appropriatefor ecological purposes or protection of cultural heritage.

· Manage during incidents according to HMZ2 guidelines.

RESOURCE INFORMATONDownfall Nature Reserve (496 ha) was gazetted on 1st January 2001. For the purposes of the Fire Management Strategy, DownfallNature Reserve will be referred to as the “Reserve’, unless otherwise stated.The Reserve straddles a ridgeline that stretches from Humula to Tumbarumba. The reserve is approximately 26kms south-west ofBatlow, NSW. The reserve is similar to Courabyra Nature Reserve, 16kms to the south south-west, being an island of nativevegetation supporting an array of endangered species and habitat in a landscape dominated by pine plantations. Threatened speciesinclude squirrel gliders, brown tree creepers, diamond firetails, barking owls and turquoise parrots.Access to the west of the reserve is through private land, via Canaarvan Trail off Downfall Road or via State Forest trails to thesouth. There is no running water or dams within the reserve. Umbango Creek may not hold water during dry periods.Department ofEnvironmentandConservation

MAP 4: VEGETATION THRESHOLD ANALYSISThreshold VegetationGroup % ofReserve Interpretation & Management Guidelines

Overburnt N/A 0If identified, two consecutive fires have been recorded too close together and thearea is overburnt.· Additional fire in this area would lead to adverse fire regimes and may threaten

community biodiversity.

Vulnerable N/A 0If identified, would be overburnt if the area burns before the end of 2006.· Fire should be avoided for this year and until another analysis of thresholds is

modelled to reassess threats.

Recently burnt N/A 0If identified, the time since fire would be less than the threshold intervals. Fire thisyear would push this vegetation into the vulnerable class.· Fire should be avoided for this year, but could be assessed for proposed burning or

other program in the future.

Underburnt N/A 0

May require fire after 2006 for Asset protection, strategic or biodiversity reasons.· Planned fire may be introduced for fuel reduction burning for asset and strategic

protection programs, ecological purposes and unplanned fire events may be allowedto burn if- The vegetation community demonstrates a loss of biodiversity- conditions are suitable- the intensity meets vegetation, flora and fauna community requirements- >50% of any vegetation community group in any threshold across the

reserve is classed as Ok, Almost Underburnt and Underburnt.

- The vegetation community demonstrates a loss of biodiversity- conditions are suitable- the intensity meets vegetation, flora and fauna community requirements- >50% of any vegetation community group in any threshold across the

reserve is classed as Ok, almost underburnt and underburnt.· This area will fall into the underburnt category by the end of 2007 if it remains

unaffected by fire, but would fall into Recently Burnt if burnt in 2006.

OK 24, 26, 45,48, 49 100

Areas which thresholds have been assigned to, which don’t fall into one of the abovecategories. Fire is neither required or to be avoided.· Fire should only be applied in areas if a loss of biodiversity is demonstrated.· Where possible, >50% of any vegetation community group in any threshold across

the reserve is classed as Ok, Almost Underburnt and Underburnt.Unknown/ NoRegimeAssigned N/A 0

The fire history is too short to determine whether it is underburnt or over burnt.Areas that do not have a threshold assigned to them or there is missing data, limitingthe modelling capabilities in DEC GIS.

Note: The threshold analysis is derived from vegetation community thresholds and recorded fire history (including fire frequency andintervals). All vegetation communities should be monitored and planned fire should only be applied if a loss of biodiversity isdemonstrated. In the event of fire in this reserve, the analysis would have to be performed again to establish new threshold values.
