Stemming from previous research efforts for the National Park Service and U.S. Environmental Protection Agency, E&S has expanded investigations into effects of expected increased air temperature on more than 1,000 understory plant species characteristic of vegetation communities within National Parks. Previously developed statistical models for each species were used in this project to model the …

E&S recently developed a white paper documenting an exploratory analysis of drivers of tree growth and survival responses to climate-related variables and aspects of air pollution, among other drivers, with colleagues at EPA and partner Universities. The study utilized US Forest Service Forest Inventory and Analysis (FIA) data for more than 1,000,000 individual trees; with …

E&S has completed a research project for the National Park Service to apply niche models from a database of more than 1,500 statistical models previously developed by E&S to evaluate expected future changes in understory vegetation occurrence in response to air pollution and climate change across eight NPS units: Acadia NP, Glacier NP, Grand Teton …

E&S has initiated a project for the U.S. Environmental Protection Agency to advance statistical model development related to the response of tree growth and survival to air pollution, climate change, and forest disturbance. Working collaboratively with project partners, a primary objective of this research is to generate critical loads of atmospheric N and S deposition …
