There are no data to provide a regional context on life-history (including population-trend) of most species, including introduced/pest species.

There few data on habitat requirements of virtually all invertebrate species, most ephemeral plants, persisting CWR mammals, and uncommon vertebrate- and plant-species.

This has provided valuable information on Threatened Ecological Communities. However floristics in the northern half has not been well surveyed and analysis is required throughout.

there has been plot based floristic survey of the southern half of the subregion only

No quantitative data on the affect of exotic predators, weed colonisation, fragmentation, fire, mineral-extraction.

. There is not uniform coverage of survey and while there is some existing survey of invertebrate across sub-region most of this has not been sorted identified or analysed yet.

Most reserves don?t have long-term survey data on species p/a even for vertebrates.

systematic fauna survey data is mainly confined to vertebrates and selected invertebrate taxa.

Existing vegetation mapping (Beard) does not cover most southern ? of subregion.

Few reserves have detailed vegetation mapping available.

No regolith mapping available.

Vegetation map resolution is 1:250 000 at best.
