Data Gaps Notes
Avon Wheatbelt 1 (AW1)
Ecological and life history data

Critical to identifying priorities and appropriate management responses in the fragmented and largely cleared landscape of the subregion.

Data on various population demographic parameters, resource requirements and landscape variables are required to model population viability for a range of species with different life history strategies.

Measures of various habitat and landscape variables.

Document the floristic variation within and between vegetation sub-associations, particularly for management purposes.

The assumption that vegetation characteristics can be used as habitat surrogates for fauna needs to be investigated more thoroughly.

A knowledge of fire regimes and histories for reserves and areas of remnant vegetation, and data on the effects of fire on flora and fauna based on their life history attributes.

Investigate the validity of using birds as indicators for all fauna.

Investigate the validity of vegetation as a habitat surrogates for all fauna.

Investigate what constitutes a viable population (Lambeck, 1998) and an understanding of metapopulation dynamics for various flora and fauna species in a fragmented landscape.

Surveys of birds, small terrestrial mammals, reptiles and select invertebrate groups across the landscape.

The continued use of the focal species approach for biodiversity conservation planning across the subregion requires further research.

systematic vegetation survey and mapping of all vegetation remnants to the sub-association level.

A standardised database and GIS application is also essential for data querying and management.

Require equivalent scale mapping of soil-landscape units.
