scale in nature assets

The nature assets look very nice and thanks for the effort - but:
1- certain trees leafs are missing alphas (Sycamore, Willow etc…)
2- their is no consistent scale (tiny palms, giant willows)

Can you guys do something about it?

I went ahead and resized the Terrain Assets to common tree sizes at mature age (although bamboos don’t have limits and Banyans can grow gigantic and are usually multi trunk), also added colliders and tree physics material and fixed thin tree material assignment.
