Diversification of income sources on dryland mallee farmland will become increasingly important if drought frequency increases and cropping success becomes more of a gamble.

Positive effects of extension of areas of native vegetation include:

EnviroNova is currently conducting trials of revegetation techniques in dryland mallee areas with a particular view of establishing a carbon income stream for landholders.

We also have a trial site developing an innovative biodiverse revegetation system in the higher rainfall Adelaide hills.

Conservation of remnant native vegetation.

Australian farmlands and peri-metropolitan areas have been extensively cleared. For example less than 10% of native vegetation remains in the Mt Lofty Ranges adjacent to Adelaide.

Conservation of remaining native vegetation is important because re-vegetation can't replace complexity built up over very long time periods.

In fact, extension of native vegetation through natural seeding by widening roadside vegetation areas or fencing off corners of paddocks is as important as artificial revegetation programs.

Once existing blocks of Native vegetation have been properly conserved, they can be linked by revegetation. As climate change progresses and bird, mammal, reptile & invertebrate species will require more extensive migration corridors to survive.

Restriction of grazing pressure on native vegetation is important. Grants for heritage listing and fencing to exclude stock can be accompanied by grants from increasingly popular "bush tender" biodiversity management programs.

The aim is profitable farmer and indigenous custodian management of biodiversity.
