In the eastern US, adult trees adapt and acclimate to local climate

Trees growing in temperate forests in the eastern US show strong adaptation or acclimation to local climate. So reports a new study that analyzed more than 23,000 tree cores to investigate how adult trees respond to changes in climatic conditions.

Thanks to climate change and wetter weather, forest soils are absorbing less methane

Farming, energy production, and landfills produce methane, a potent greenhouse gas. Forests can remove methane from the atmosphere through the activity of soil bacteria. But increasing precipitation – a symptom of climate change – is making it harder for forest soils to trap greenhouse gases, creating a feedback loop that exacerbates global warming.

Stopping the importation of forest pests

What can be done to prevent the importation of forest pests? Cary Institute forest ecologist Gary Lovett talks about changes to the US Farm Bill and actions that would build on current policy proposals to prevent new forest pests from arriving in the US.

Imported forest pests: What are the impacts and who pays?

Imported pests threaten forest health, local economies, and the benefits trees provide to cities and communities.

Tree-SMART Trade

Growing reliance on both trees and trade makes imported forest pests the most pressing forest health issue in the US today. Five high-priority policy actions that build on proven prevention measures can reduce the arrival and establishment of new forest pests.

Effects of Invasive Hemlock Woolly Adelgid on Northeastern Forests

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.

Base Cation Depletion: Organic Matter Quality & Microbial Processes

We are analyzing how changes in soil base status can influence microbial physiology, organic matter quality, and microbial activity in northern hardwood forests at Hubbard Brook.

Ecosystem Effects of Exotic Forest Pests

Over the last century, forests of the eastern U.S. have been plagued by a series of devastating introductions of exotic pests.

Long-Term Monitoring of the Forest Ecosystem at Cary

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.

Pulsed Resources and Consumer Communities in Terrestrial Systems

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.

Buell-Small Succession Study

Post-agricultural plant community succession is being studied in permanent plots in central New Jersey.

Effects of Beech Bark Disease on Catskill forests

This project is focused on the consequences of the invasion of the beech bark disease (BBD) in northern hardwood forests, which dominate the uplands of the northeastern U.S. and southeastern Canada.

Catskill Mountain Ecosystems

This project is primarily focused on understanding the ecology and nutrient cycling of Catskill forests and the responses of the forests to stresses such as air pollution and introduced pests.

Controlled Focused Hunting

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.

Monitoring Trends in Deer Abundance

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.

Monitoring Deer Browsing

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.

Snow Depth & Soil Freezing as a Regulator of Microbial Processes

In the northern hardwood forests in New Hampshire we are analyzing how soil freezing events cause root and microbial mortality, which can lead to increased rates of N and P mineralization and loss.
