Dr. Lovett's research is primarily focused on how perturbations such as air pollution, introduced pests and pathogens, and insect defoliators affect forest nutrient cycling. 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.
Due to their proximity to the New York-New Jersey metropolitan region, the Catskills receive high rates of atmospheric nitrogen deposition. Our research is focused on identifying the major controls on nitrate export from these forested watersheds. The Catskill 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.
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.
