Hudson Valley

Drought, Climate Change & Humans:
25 Years of Tree-Ring Research

 

The tree-ring lab has studied forested ecosystems in the Hudson Valley (HV) for more than 25 years. The first two studies included a study of long-term drought, the first of its kind in the eastern US.

Since then the lab has developed a network of sites in the valley comprised of several species that have been used to study climate and tree growth at the regional and continental scale.

Several old-growth eastern hemlock stand have been sampled to study the influence of climate across its entire range of distribution.

The Hudson Valley lies at an important biome transition zone between the oak-hickory, northern hardwood and boreal forest types.

It has nearly 10 boreal and more than 20 southern temperate tree species living near or at a range limit. Its position at a large-scale ecotone makes it rich in biodiversity.

The biodiversity plus unique geographic & ecological qualities make it a natural laboratory for studying the effects of climate change on forested ecosystems.
