Area calculation for trees

I have a project where trees, shrubs and groundcovers will be used. While the area coverage of shrubs and groundcovers is relatively easy to calculate, trees are a bit more tricky. Quite a bit of the trees in the landscape plan are native/adapted and several units of each will be used. How can I calculate the area coverage of trees? Is it by canopy spread? Pot size in liters (then convert to sq. meters? Also, can non-native but adapted species of vegetation be used as long as they are non-invasive?

Muhammed, adapted vegetation is fine for this credit. I would suggest double-checking the LEED definition of adaptive.Regarding the site area, I would look at the landscaped area. If there is a tree with a canopy over pavement, then counting the pavement would not fit with the credit intent. However, counting the canopy if it is over other vegetated or landscaped space would be valid.
