A forest with larger trees and more extensive root systems will have a stronger effect than a forest with smaller trees with less extensive root systems.

Different tree species can also be more or less effective at functioning as a buffer. "Thirsty" trees typically do a better job of taking up water when it's wet and continuing to release water when it's dry. (Unfortunately, many new tree plantings favor more drought-resistant trees because they are easier to grow in clearcut fields, which are drier than forests.)

So, because I don't know much about this region specifically, these are my two questions:

Has there been a change in tree biomass in the region?

Has there been a change in the tree species makeup of the region?
