When developing this I used models which I sadly cannot share. So you have to model them yourself or download them from the internet. (I'll add this to the readme) I can recommend TurboSquid and cgtrader for good quality models.
One thing to keep in mind when making the .usd files for the trees is that the script expects 0, 0, 0 to be the location where the tree should intersect the ground plane.
