If you have RGB images, you could use EGI=2*G-B-R and a threshold to
segment plants (if they dont overlap in the image), then count it.

But since the plants in your images overlap and other areas are green,
too, this might be difficult (you need to find something to segment
trees based on other features, e.g. to segment the "star"
structure/centers of the trees).
