Re satellite. At Sentinel resolution (10-20m) not much, maybe enough to distinguish plantation from natural forest spectrally. At Planet (3m) and below you can start to see large individual trees. It's very difficult to accurately measure biodiversity from space. Drone imagery might get you species visually but until we have widespread hyperspectral (see ESA CHIME) 12-13 bands is what most people work with.
