Lastly, it is hard to tell the size of the trees that are producing the bush tucker in the photos. The document you sent to Adam says that bush tucker producing trees can grow from 10-45 metres tall. This was surprising. The photo makes it look as if bush tucker is obtained from small bushes (small, like a strawberry plant for eg.).
This will have an impact on the height of the nursery, if you want big trees growing inside of it.
