What you can do to make Australia great.
The Australian landscape is very very old . Its soils are most commonly shocking old degraded things that set like concrete in summer , and turn to soup in winter : In SW Victoria some deep sands would grow mainly insects until the soil processes were modified. Now some of these deficit rich soils are some of the most productive in Australia Most landscapes have been exposed to extremes of weathering, wetting and drying and our vegetation is a bit mono cultural and predictable because of burning and these drivers
Trees sustainability can for example be improved on many of our old soils ( always check your type ) The one below is called sodic because the sand clay mix is dispersed by sodium salts.
By mixing the million year ago soupy layers with other layers or carefully removing some of the soupy stuff you can improve the sustainability and health of most plants on your patch . You have to make sure you save some topsoil and deal with the increased erosion risk created - like using lime or gypsum or structural controls.
Hilling up is helpful in the same vein for improving soils, but our soils are so dispersable that you must consider scale and slope even with landscapes with a fall of more than 2% ( check your erodibility risk - a must in Australia )
Once you do this you will find plants of all kinds can build up rather than lose their organic matter . They won't do this if their roots are always dying off because the rain keeps them wet .
