By now the lesson is clear: Burning coal and petroleum produces carbon dioxide, the heat-trapping gas that contributes to the warming of our globe. That alone is enough reason to believe fossil fuels are not a sustainable basis for society long-term.
Ecologist Jerry Jenkins has been documenting the flora and fauna of the Northern Forest for the past 45 years. This visually-rich lecture distills his findings, with a focus on inspiring conservation and informing environmental education.
The Harvard Forest, in collaboration with the Cary Institute of Ecosystem Studies, has launched a new Science Policy Exchange project on forest pests and pathogens. This project addresses growing concerns about damage to trees, forests, and local economies caused by introduced insects.
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.
On the rugged roadway approaching Fray Jorge National Park in north-central Chile, you are surrounded by desert. This area receives less than six inches of rain a year, and the dry terrain is more suggestive of the badlands of the American Southwest than of the lush landscapes of the Amazon.
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.
