I'm confused of how the vegetation/plants will be measured. If you have an open and vegetated space compliant to the requirement, and your vegetated space is composed of grass/lawn, planters, trees, etc. how will you measure the planters  and trees considering that grasses is not counted as vegetated, is it by how big the trunk of the trees or how big the shade on the trees? I know I was too technical but I'm really confused how to treat it as a way we can comply the credit requirements.

Thank you in advance.
