Because of our initial study, we hypothesized that the trees in the urban watersheds, because of all this leakage, probably wouldn't be as sensitive to climate changes such as droughts. When there's a drought, the trees don't grow as fast, so they grow skinnier rings. So we can use trees as sort of an indicator of past droughts.
The trees in the urban watershed were much less sensitive to drought than the rural watershed trees. It's actually a positive consequence to the bad news of water loss.
