E&S recently developed a white paper documenting an exploratory analysis of drivers of tree growth and survival responses…

The European VSD+PROPS model was applied to estimate changes in understory vegetation in response to changes in climate and atmospheric nitrogen deposition at three forested sites in the eastern United States.

Minimally disturbed lakes were determined from available GIS data (e.g. land use, roads, aerial photography) for comparative use in EPA’s national survey of lake health. A series of maps was generated for each candidate reference lake and analyzed for evidence of disturbance.

E&S Environmental Chemistry, Inc. was contracted by the U.S. EPA to draft a synthesis report on ecological effects of atmospheric deposition of oxides of sulfur (S) and nitrogen (N).

E&S Environmental Chemistry, Inc., working together with the U.S. Environmental Protection Agency (EPA) and under the direction of the USDA Forest Service (USFS), is assisting the USFS in the development of a decision-support system (DSS) for critical loads (CL) of atmospheric sulfur (S) deposition in the southeastern United States.

Land management and natural resource public policy decision-making in the United States increasingly relies on two resource damage/recovery paradigms: ecosystem service (ES) and critical load (CL).
