water tables and trees

[Boilerplater]

I’ve noticed the same thing in Appalachian mountain areas and even lower coastal plain areas where grade changes and the construction of basements likely affected the level of the water table.  When trees are mature and have spent most of their life with a source of water at a level where they’ve put most of their roots, they’re not going to make it when that water level is suddenly changed.  Have you checked the journal of the International Society of Arboriculture?  Hopefully they have an online search tool for the back issues.  I think its highly likely that a study as you describe has been done.  For years I worked in an office where they had a subscription, and these were the kinds of issues they would cover.  Seemed like any issue affecting tree health was covered.
