Natural Resource Management
 Sector Issues - Case Study
» A shift towards the xeric end of the continuum (with both
local declines in the trees that tolerate moister soil conditions
and an increase in some species that tolerate drier soil
conditions).
» A general loss of condition of tree species, although this has
been offset by the establishment of seedlings on some sites.
» Loss of some wetland species and communities.
» Recent loss of some drier site species.
» Dynamic nature of communities in both temporal and spatial
context.
» Rate of decline and rate of changes.

 Sector Issues - Lessons Learnt
» The structure and composition of vegetation on the Gnangara
Mound reflects underlying determining factors such as
landforms, soils, climate and surface soil moisture
availability.
» As the site becomes drier in a regional context the overstorey
becomes more open - so if recent annual rainfall trends
continue, it is likely that:
the overstorey will become more open
 there will be a continuing shift towards species that tolerate
drier site conditions
 loss of species and vegetation communities that tolerate wetter
and moister sites

Natural Resource Management
 Priorities
» Do we really place sufficient value on these natural
resources?
» Do we understand implications of potential changes?
Degree and rate of change - positives and negatives
 Major gaps in understanding
 At a landscape level - changes will occur

» Do we understand the implications for Industries dependent
on these values? (Wildflowers, Beekeepers, Forestry, Water
Catchments, Tourism, Ecosystem Services)
» Do we understand the implications for wider community social consequences of changing landscapes

 Needs
» Increase value of natural resources?
» Overcome structural problems in funding and human resources in NRM
(Federal, State and Regional groups).
» Increase skills and capacity of NRM teams and researchers.
» Underpin research organisations with long-term commitment (rather than
short term), including adequate resources, succession planning (as studies
take many years).
» Increase research into studying implications of change
 Degree and rate of change - positives and negatives - integrate
component into research programs
 Integrate databases to maximise return for effort
» Undertake a major review of implications for Industries dependent on these
natural resource values? (Wildflowers, Beekeepers, Forestry, Water
Production, Tourism, Ecosystem Services)
