Dr. Lovett's research is primarily focused on how perturbations such as air pollution, introduced pests and pathogens, and climate change affect forest ecosystems. His main field projects are in the Catskill Mountains and Hudson Valley of New York State and the Hubbard Brook Experimental Forest in New Hampshire.
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.
Our research is focused on identifying the major controls on nitrate export from the Catskill watersheds. These watersheds provide 90% of the drinking water for New York City residents, making the results of our research relevant to land managers as well as ecologists.
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.
Air pollutants are deposited not only in rain and snow, but also as gases, particles, and fog droplets. Measuring the deposition of all of these forms is difficult, especially in mountainous terrain, where deposition rates are strongly influenced by elevation and characteristics of the forest canopy. Knowing the rates and patterns of deposition is critical to evaluating ecosystem response to the pollutants
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.
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.
Air pollutants such as sulfur, nitrogen, ozone and mercury have serious direct and indirect effects on organisms in our region. A synthesis of research findings, written by the Cary Institute and the Nature Conservancy, reports that no major ecosystem types in the Northeast are free of air pollution effects.
The gypsy moth was introduced to North America from Europe in 1869 and has become a major defoliator of eastern hardwood forests.
Carbon released from terrestrial ecosystems is an important source of organic matter in most streams, lakes and rivers. In the Hudson River there has been a doubling in concentration of dissolved organic carbon over the past 15 years.
At the Cary Institute we monitor biological organisms in a variety of programs. One of those programs uses phenology, the study of the timing of seasonal changes and life cycle events.
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.
Each year, more than 25 million shipping containers enter the U.S. All too often, highly destructive forest pests are lurking among their imported goods. Wood boring insects arrive as stowaways in wood packaging, such as pallets and crates.
Efforts to prevent new pests are not keeping pace with escalating trade and must be strengthened if we are to slow the loss of our nation's trees. Dr. Gary Lovett describes the threat and the steps that can be taken to save our forests.
Forest ecologist Gary Lovett discusses the economic and ecological impacts of forest pests and the possible policy implements that may reduce the threat.
Debate about the Trans-Pacific Partnership overlooks an unintended consequence of increased trade with Asia – the assault on America's trees.

Most of us are familiar with ammonia as an irritating gas that is emitted from window-cleaning fluids. It is a great way to cut through grease that has condensed on glass.
Woodland pools are temporary wetlands that provide important habitat to forest wildlife. They also help mitigate floods. While land development is a major threat to woodland pools, there are also subtle changes that undermine their health.
In the Northeast, one of the first signs of spring is the unmistakable calling of the spring peeper. While this small frog weighs only a few grams, its mating call is louder than that of many songbirds ten times its size.
Though not in the news as much as it once was, acid rain remains a problem. Power plants, factories, and vehicles give off sulfur and nitrogen oxide emissions, which react in the atmosphere to form sulfuric and nitric acids. These acids are then deposited back onto the landscape in rain, snow, fog, or particles.
Cary Institute’s Gary Lovett discusses how several invasive species are ravaging regional forests.
