Vegetation profiles and management recommendations


Vegetation extent information and species lists contained in the vegetation profiles are based on analysis from the National Vegetation Information System (NVIS), including analysis of Major Vegetation Subgroups and NVIS Level V descriptions. Please see http://www.environment.gov.au/node/18930 for more information.

The management recommendations have been drawn from EPBC Act Recovery Plans, EPBC Act Ecological Communities Listing Advice and other sources. The recommendations are indicative only. Systematic reviews of management literature, consultation processes and improved Natural Resource Management program monitoring and evaluation will support development of a comprehensive set of management recommendations over time.

Ensure only authorised vehicle access for operational purposes. Otherwise, restrict access to pedestrians only and ban trail bike and BMX riding within remnants.

Avoid changes to groundwater levels and water quality by maintaining and replanting native vegetation in lands adjacent


to remnants.

Exclude stock.

Minimise spray drift from adjacent agricultural lands.

Minimise ground and surface water extraction.


Undertake revegetation where there is no evidence of regeneration. Ensure seed and tubestock are locally sourced and attempt to replicate the vegetation structure and diversity of local, high quality remnants on similar soils and aspect.

Fire intervals should be a minimum of ten years apart. Use mosaic burning techniques, applied in a variety of seasons and intensities. Retain a range of vegetation age classes throughout
the mosaic.

Ensure that fire regimes take account of the lifecycles of obligate seeders with long juvenile periods. Fire should not occur more frequently than twice the juvenile life stage of the slowest


maturing species.

Areas that have been recently burnt should be monitored


for weeds.

Manage Phytophthora outbreaks as this affects food sources for wildlife, particularly honey possums and other small marsupials.

Many species are pollinated


by marsupials.

Manage Weeds including Victorian tea-tree, Watsonia, Bulbillifera, African Lovegrass
and Veltgrass.

Phosphorus negatively impacts on the regeneration capacity of native vegetation and encourages


proliferation
of weeds.

Actively manage cats, rabbits and foxes.

Undertake fox and rabbit management simultaneously to avoid foxes switching to predation on native species, or increases in rabbit populations.

Manage native herbivores to prevent
overgrazing.


Maintain strict hygiene protocols to avoid spreading Phytophthora by vehicle tyres, earthmoving
machinery
and boots.

Treat dieback with phosphite in early Summer, and repeat 4–5 weeks later. Sites should be treated for a wide area around


an infected site.

Remove all parts of badly affected plants, including as much of the root system


as possible.

Manage public access to control


the spread
of dieback.

Encourage uptake of conservation agreements and covenants on private land. See: http://www.dpaw.wa.gov.au for information on covenants and private land conservation.

Ban firewood


harvesting.

Protect
paddock


trees.

Fence, and exclude stock from remnants.

Maintain native vegetation remnants and paddock trees as this provides protection against dryland salinity.

Fence paddock trees. If no saplings appear after fencing and stock exclusion, replant paddock trees with tubestock from locally sourced seed.

Use shade cloth to construct artificial paddock shade and prevent stock camping under trees.

Minimise ground and surface water extraction.


Overstorey eucalypt species may not regenerate if sites have been previously grazed. Sites that have retained mosses and lichens are more likely to regenerate naturally.

Undertake revegetation where no natural regeneration occurs. Ensure seed and tubestock are locally sourced and attempt to replicate the structure and diversity of local, high quality remnants on similar soils and aspect.

Monitor and actively manage weed species in rehabilitation sites.


Reduce the incidence and extent of wildfire by undertaking mosaic burning and maintaining diversity of vegetation age classes in unburnt patches.

Maintain existing fire-breaks with a minimum of soil disturbance, using herbicides or mowing wherever possible.



Add coarse woody debris (such as untreated railway sleepers) into sites where fallen timber has been removed.

Maintain and protect hollow-bearing trees. If few or no mature hollow bearing trees are present within remnants, provide nesting boxes for mammals and birds. Monitor regularly for invasive species.

Ensure fencing is wildlife fencing. No electric fencing and no barbed wire.

See http://www.dpaw.wa.gov.au/get-involved/wildlife-rehabilitation-and-courses for more information.



Maintain strict hygiene protocols to avoid weed spread.

Avoid adverse impacts of chemicals or other mechanisms to manage weeds on native vegetation.



Actively manage cats, rabbits and foxes.

Undertake fox and rabbit management simultaneously to avoid foxes switching to predation on native species, or increases in rabbit populations.

Manage native herbivores to prevent overgrazing.

Create buffer zones and fence remnants.

Protect groundwater levels and water quality through maintaining and replanting native vegetation in adjacent lands.



Exclude stock where possible.

Use rotational grazing if sites must be grazed.

Protect soils from wind and water erosion by maintaining native ground cover.


Undertake revegetation where no natural regeneration occurs. Ensure seed and tubestock are locally sourced and attempt to replicate the structure and diversity of local, high quality remnants on similar soils and aspect.

Develop and implement appropriate fire management plans. Please seek advice from your local NRM organisation on appropriate regimes.

Protect remnants from clearing.

Protect from bore water extraction. Falling water tables are a key threat to the health of forest systems in Western Australia.

Protect hollow-bearing trees.

Protect standing dead trees and fallen timber.

Buffer remnants adjacent to agricultural lands with native vegetation.


Minimise spray drift from adjacent agricultural lands.

Maintain native vegetation remnants and paddock trees as this provides protection against dryland salinity.

Fence paddock trees and exclude stock. If no saplings appear after fencing and stock exclusion, then replant with tubestock from locally sourced seed.


If remnants show little evidence of regeneration, revegetate with locally sourced seed.

The ALCOA bauxite mine rehabilitation sites provide excellent examples of Jarrah Forest rehabilitation. See http://www.alcoa.com/australia/en/info_page/mining_rehab.asp

For more information on rehabilitating forest sites, please contact your local Natural Resource Management region.


Too frequent and intense fires can impact negatively on plants that have long juvenile phases or are slow to set seed.

Ensure remnants are monitored closely for weeds after planned fire or wildfire.



If fallen timber has been removed from remnants, replace with coarse woody debris (such as untreated railway sleepers). Fallen timber provides habitat for wildlife.

Maintain and protect mature trees as it can take 150-180 years for tree hollows to develop. Hollows provide shelter and breeding habitat for mammals and birds.

If few or no mature hollow bearing trees are present within remnants, provide nesting boxes. Monitor regularly for invasive birds and feral honey bees.

Ensure fencing is wildlife fencing – no electric fencing, and no barbed wire.

See http://www.dpaw.wa.gov.au/get-involved/wildlife-rehabilitation-and-courses for more information on wildlife rehabilitation.


Manage Bridal Creeper and Blackberry.

Actively manage foxes, cats, rabbits and pigs.

Undertake fox and rabbit management simultaneously to avoid foxes switching to predation on native species, or rabbit population increases.
