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.

Urban Plant Diversity

It's spring and a young man's fancy may turn to.......gardening. Of course, it is tempting to find ornamental plants that no one else has in the neighborhood, so a significant fraction of the nursery trade focuses on exotics—species that do not occur locally.

Stop importing forest pests

Recent news of the discovery of the emerald ash borer in Franklin County and the hemlock woolly adelgid near Lake George crystallizes the threat that imported forest pests pose to the Adirondacks. The emerald ash borer, a small green beetle from Asia, is poised to wipe out all of the ash trees in the region — and potentially North America.

Tree-SMART Trade

Growing reliance on both trees and trade makes imported forest pests the most pressing, and under-appreciated, 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.

Effects of Gypsy Moth on Nitrogen Cycling

The gypsy moth was introduced to North America from Europe in 1869 and has become a major defoliator of eastern hardwood forests.

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.

Zebra Mussels and the Hudson River

Zebra mussels appeared in the Hudson in 1991 and fundamentally transformed the ecosystem. The zebra mussel invasion is linked to losses of native mussels and changes in the fish community.

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.

Exotic Earthworms & Northern Temperate Forests

Earthworms effect microbial nitrogen cycling and ecosystem nitrogen retention. Earthworm invasion of north temperate forests will have large consequences for nutrient retention and uptake in these ecosystems.
