Invasive pests and pathogens threaten the health of Northeastern forests. Cary Institute ecologist Gary Lovett has spent his career investigating the impact that species like the hemlock woolly adelgid and beech bark disease have on Catskill Mountain ecosystems.
In Ballard Park in Ridgefield, there are some lovely, thick-trunked, big-canopied beech trees, perfect for providing shade on a summer's day. They are old trees and despite their beauty, they're not healthy. They have beech bark disease.
Many of us have experienced a restorative walk in the woods. But does associating with trees really make us any healthier? After investigating the loss of some 100 million ash trees in the Eastern and Midwestern United States, Forest Service researcher Geoffrey Donovan and his colleagues suspect that the answer is yes.
Woodland pools are temporary wetlands that provide important habitat to forest wildlife. They also help mitigate floods. While land development is a major threat to woodland pools, there are also subtle changes that undermine their health.
Bubbling brooks and streams are a scenic and much loved feature of forest ecosystems, but long-term data at Hubbard Brook Experimental Forest suggests that more productive forests might carry considerably less water.
Following an exhaustive review of more than fifty years of long term data on environmental conditions at the Hubbard Brook Experimental Forest in the White Mountains of New Hampshire, the results are clear: spring is advancing and fall is retreating.
While walking through the woods in the Hudson Valley, it is common to stumble upon the remnants of stone walls. Now mossy and overgrown, they date back to a time when agriculture dominated the landscape.
