The Valley as a Natural Laboratory

Unique geographic,climatic & ecological qualities make the Hudson Valley a natural laboratory for studying the effects of climate & forested ecosystems.

Nearly 60% of the tree species found east of the Mississippi River and 89.9% of NYS trees can be found within the valley. The valley's high tree diversity is a result of these uniques attributes.

Despite >300 yrs of complex & intense land-use, pockets of old- & old 2nd growth forests can be used to reconstruct climate histories and natural long-term variations.

Understanding natural patterns & dynamics of forested ecosystems may help anticipate the impacts of future anthropogenic changes.
