Birds
and flora of the grassy woodlands have received a high profile due to
recent research and conservation efforts. It is important when making
management recommendations based on this research that the other less
conspicuous grassland fauna such as reptiles and invertebrates are also
considered.
Management for one species may actually conflict with management for
another species. In management of threatened species in grassy sites in
the Southern Tablelands, we have been faced with just such dilemmas of
conflicting management needs.
For example:
- Shrubs planted to enhance a site for woodland birds may be a problem
for its reptiles and invertebrates, as well as the other flora that
depends on an open grassy ground layer. There will be a temptation to
exclude fire, grazing, slashing or other methods of biomass control
while the shrubs are establishing, but these may be essential for other
grassland plants and animals.
- Managing an isolated site by burning a large proportion of the site
will kill individual reptiles and invertebrates and may cause local
extinctions. On the other hand, not controlling biomass (grass buildup)
can also cause problems. Patch burning, in which small areas of the
site are burnt in a mosaic is probably best if burning is to be used.
- Allowing regrowth of trees in a site that currently has few trees
may reduce the site's attractiveness as habitat for specialised grassland
reptiles.
- At one site fenced off to stop grazing because of a salinity problem,
kangaroo grass is starting to take over from the wallaby grasses which
are used as food plants by caterpillars of the endangered Golden Sun
Moth.
A general rule of grassy ecosystem management is that if a certain
management regime has been applied for a long time, and this management
has meant the retention of a range of species (both fauna and flora) at
a site, then this management should be continued at least until better
information is available.

Designing management regimes to accommodate different threatened species
may mean one or more of the following:
- Reduce the area proposed to be burnt/slashed/grazed to small patches,
rather than large areas or the entire site.
- Aim to retain the site's structural diversity, not just the species
that are present
- Plant shrubs only in areas where this will not reduce habitat for
reptiles and invertebrates.
- Allow tree recruitment only over parts of a site to allow for structural
and floristic diversity and habitat diversity for reptiles and invertebrates.
- Fence off only areas directly affected by salinity, not the entire
site (although, remember that salinity has the habit of spreading over
time!), so that biomass control and reduction of competition by controlled
grazing can continue.
- For sites with a history of grazing, reduce grazing to times or periods
that allow more sensitivity to the retention of a range of species,
rather than eliminating grazing altogether.
If a threatened species is likely to occur on the site consult a Threatened
Species Officer from NPWS or other specialist for advice about obligations
under the Threatened Species Conservation Act, 1995, such as the
need to obtain a licence to undertake actions.
Actions include any management works undertaken at the site, or trapping
or other survey work that may be necessary to ascetain the presence if
the species.
