Letter signed by 65 research scientists sent to U.S. senators working on the Energy Policy Modernization Act. The Senate has accepted an amendment to the act which would legally designate forest biomass to be "carbon neutral."
There is very cool science going on at Hubbard Brook. Scientists from Cary and other research institutions created an experimental ice storm that will improve understanding of short- and long-term effects of ice on northern forests.
A team of scientists in New Hampshire succeeded this week in capturing one of nature's most destructive forces - ice - and corralling it in two large research plots on the Hubbard Brook Experimental Forest.
Hemlock is a "foundation" tree species in eastern forests and its presence defines the properties of a unique ecosystem that is presently declining due to the introduction and spread of an invasive insect, the hemlock woolly adelgid.
We measure key aspects of forest productivity, species composition and nutrient cycling in the mixed-oak forest at Cary. This long-term monitoring allows us to track trends in the forest ecosystem resulting from air pollution and other stresses.
In forests dominated by mast-producing trees,consumers are confronted with the sporadic production of abundant resources. Animals, such as the white-footed mouse and eastern chipmunk, rely on these pulsed resources.
Stabilizing a deer population requires a balance between annual recruitment and mortality. For a population reduction, mortality must exceed recruitment. Using hunting as our primary management tool, our hunters are required to focus their efforts on culling females as well as males.
Presently, hunter observations are used as the technique to assess if Cary controlled hunts are stabilizing local deer numbers. Night spotlight counts of deer have been used to index trends in abundance in the past. The observations of deer by bow hunters, has yielded data that have correlated very well with spotlighting numbers with the observation data easier and less expensive to obtain.
Since 1983, Mr. Winchcombe has been monitoring the intensity of deer browsing on the major tree species on the Cary Institute's grounds. Browsing intensity varies annually, with over-winter browsing linked to total winter snowfall amounts. Browsing studies help govern deer management strategies, with heavy browsing highlighting the need to further reduce local deer numbers.
