New Brunswick environmental group finds success selling carbon offsets
Community Forests International, a Sackville-based forestry and environmental group, has been making about $70,000 per year on their 71 hectare woodlot by selling carbon offsets to five Canadian companies. These companies are paying CFI to manage this land sustainably.
New NASA probe will study Earth's forests
An instrument being developed for the International Space Station will provide a unique, three-dimensional view of Earth's forests, helping to fill in missing information about their role in the carbon cycle.
For trees, an earlier spring than ever
Every spring, as the weather warms, trees in forests up and down the east coast explode in a bright green display of life as leaves fill their branches, and every fall, those same leaves provide one of nature's great color displays of vivid yellow, orange and red.
Old trees grow faster, store more carbon
For most species, the biggest trees increase their growth rates and sequester more carbon as they age, scientists now say.
Former clearcuts can be future carbon sinks
Managing forests for carbon storage can significantly reduce temperatures over the coming century, according to Dale Prest.

Earthworms and forest soils
Vermont scientists ponder the good, the bad and the ugly about earthworms.
Death of a spruce tree
Scientists study black spruce growth, death and carbon storage in the boreal forest.
Carbon markets can have negative impacts, too
The development of carbon markets could result in food supply problems and degraded ecosystems unless the schemes are based on more than just paying landowners for planting trees.

Red spruce recovers
In the 1970s, red spruce was the forest equivalent of a canary in the coal mine, signaling that acid rain was damaging forests and that some species, especially red spruce, were particularly sensitive to this human induced damage. In the course of studying the lingering effects of acid rain and whether trees stored less carbon as a result of winter injury, U.S. Forest Service and University of Vermont scientists came up with a surprising result -- three decades later, the canary is feeling much better.
