What are the ecological effects of moderately high and prolonged concentrations of nitrogen deposition on an ecosystem?
There are many sources of nitrogen which eventually get deposited out of the atmosphere and onto the land/surface. Typically higher levels of nitrogen compounds are emitted near urban and roadway locations, raising the levels of nitrogen deposited on the nearby landscape. **What are the ecological effects of moderately high (at least double background) and prolonged concentrations (10+ years) of nitrogen deposition on an ecosystem?** Please be specific about which type of ecosystem your comments are intended.
