Grant history of an LTER site
The Hubbard Brook (HBR) Experimental Forest LTER project began in 1988, drawing on a history of forest ecosystem research that began in the 1950s, and has the continuing overall goal of improving understanding of the structure and function of Northern Forest ecosystems and their responses to environmental change and disturbance. This project will advance the… Read more »
The Hubbard Brook (HBR) Long-Term Ecological Research (LTER) project is an interdisciplinary research program focused on improving the understanding and management of Northern Forest ecosystems. These important natural resources that contribute ecosystem services such as carbon storage, nutrient cycling, water and air purification, and wildlife habitat are impacted by natural and man-made disturbances. Those disturbances… Read more »
The need for long-term research on forest ecosystems has accelerated markedly in recent years. Traditional interests in provision of wood products and clean water have expanded to include climate mitigation, biodiversity conservation, and ecological and social resilience. Forests are complex ecosystems, dominated by long-lived organisms, and are highly connected to adjacent ecosystems at many scales…. Read more »
The Harvard Forest in central Massachusetts has been an active research facility for the study of forest ecosystems since 1907. The central theme of this project is a comparison, in the context of Long-Term Ecological Research (LTER), of historically important physical disturbances and recent and projected chemical disturbances in terms of their effect on forest… Read more »
Harvard Forest Temperate forests, such as those that dominate the eastern United States, are critically important ecosystems at regional to global scales. They harbor a diversity of species and habitats, provide essential resources, offer important amenities to densely populated regions, and comprise key elements in global carbon budgets. Understanding the structure, function and patterns of… Read more »
The Harvard Forest LTER (HFR) investigates forest response to natural and human disturbance and environmental change over broad spatial and temporal scales. Involving many researchers and students from a dozen institutions, HFR embraces the biological, physical, and social sciences to address fundamental and applied questions for dynamic ecosystems. Its work on the ecological effects of… Read more »
The Harvard Forest LTER program is a two decade-strong, integrated research and educational program investigating forest responses to human and environmental change across the New England region. HFR engages more than 30 researchers, 200 graduate and undergraduate students, and dozens of institutions in research that incorporates social, biological, and physical sciences. Scientists conduct this work… Read more »
For thirty years the Harvard Forest Long Term Ecological Research (LTER) program has been dedicated to understanding New England’s forests. The heart of the program is a group of scientists and students who do experiments and measure the many ways that forests change over time. They are especially interested in how forests are linked to… Read more »
9411975 Foster Forest ecosystems worldwide are changing in response to direct and indirect human activities. These present a significant challenge requiring interpretation of the driving variables across wide temporal and spatial scales. These dynamics also present an opportunity to evaluate the mechanisms regulating ecosystem responses. Harvard Forest LTER I assessed temperate forest response to human… Read more »
This research project will examine the general hypothesis that desertification has altered a previous, relatively uniform distribution of water and nitrogen by increasing their spatial and temporal heterogeneity, leading to changes in community composition and biogeochemical processes in Chihuahuan Desert ecosystems. The Jornada Experimental Ranch (southern New Mexico), with a 75-year history of rangeland research,… Read more »
