Since Wirrapunga is grassy woodland, the woods are extremely important. Wirrapunga is basically a stringybark habitat. Both the brown stringybark (Eucalyptus baxteri) and the messmate or yellow stringybark (Eucalyptus obliqua). As I cleaned out the woody weeds, including the introduced pinus radiata, I needed to encourage a suitable concentration of trees to take their place. The density of the trees is extremely important.
The idea is to look at a mature forest. In my case that was a mature stringybark forest, and try to emulate the amount of light hitting the ground with your tree planting. This means that you need your trees to be much closer when they are young than when they grow older. I try to get the spacing right for when they are about ten years old.
To plant the trees I simply collect some seed from as near as possible. In my case this meant actually collecting them from Wirrapunga since I was fortunate to have a few mature stringies on Wirrapunga. I then cleared a small area at each place I wanted a tree to grow and sprinkled a few seeds on the spot and left the rest to nature. I then had to keep an eye on them and weed out any competition until they were large enough to manage on their own.
I did have one particularly bad area of woody weeds on my lower boundary. This was about 0.2 of a hectare and was where a previous garden had been located. Since this area was nothing but introduced plants, I heavily seeded this with stringy seeds.
The tree species at Wirrapunga are as follows:
| Genus | Species | Common Name |
| Eucalyptus Eucalyptus Eucalyptus Eucalyptus Eucalyptus Eucalyptus Eucalyptus Acacia Allocasuarina |
baxteri cosmophylla fasciculosa leucoxylon obliqua dalrympleana viminalis melanoxylon verticillata |
