Getting smarter about imported forest pests

Podcast

Cary forest ecologist Dr. Gary Lovett answers questions about costly and destructive forest pests and pathogens and the preventive measures that both government and individuals can and must take in the face of this environmental pressure.

The 'slow motion crisis' that's facing US forests

The U.S. is subject to the introduction of 2.5 new invasive insects into its forests ever year, according to a comprehensive analysis of this problem by Gary Lovett of the Cary Institute of Ecosystem Studies and a group of 15 colleagues. And that number is just for insects — it doesn't count diseases, such as sudden oak death.

NY's AG leads coalition against bill to strip state authority on ship discharges

Podcast

New York's Eric Schneiderman and 10 other attorneys general have sent a letter to U.S. Senate leaders. The letter urges opposition to a bill that would eliminate states' authority to protect waterways from ships' polluted discharges, making it easier for non-native species to invade the Hudson River and Great Lakes.

Study: Invasive bugs found in fallen trees years after storm

They may be down but they're not out: Damaging insects can emerge from fallen trees and logs for several years after a major storm, according to a U.S. Forest Service study that reinforces longstanding warnings against moving firewood from place to place.

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.
