Notes : This paper
discusses the current status of forested, wetland, freshwater and
coastal ecosystems; the combined impacts of habitat alteration,
pollution and non-native invasive species on those systems; how
climatic changes could interact with existing stresses; potential
management strategies, and crucial research gaps. Changes in
climate and climate variability would significantly affect natural
ecosystems, and may pose additional threats to the
already-stressed ecosystems of the Mid-Atlantic Region (MAR).
Fragmentation of the MAR's forests may hinder the migration of
some species. Urban development and wetland losses leave the MAR's
rivers and streams and near-shore areas vulnerable to damages if
the frequency and intensity of storms increase. Inputs of
sediments, nutrients and toxic chemicals to streams, lakes and
estuaries might increase if precipitation increases. Accelerated
sea-level rise could accelerate the loss of coastal wetlands.
Estuaries are sensitive to changes in temperature, salinity and
nutrient loads, and could be adversely affected by projected
climatic changes. Populations of rare, native species could
decline, while problems with non-native invasive species, such as
kudzu and gypsy moths, might increase. The best strategies to
protect ecosystems from climatic changes may be those that reduce
other stresses, thus increasing resilience to a variety of
stresses. Societal priorities for ecosystem protection need to be
articulated, and research is needed into the values of ecosystems,
ecosystem functioning, human impacts, long-term ecological
monitoring, and management options to provide a basis for
selecting effective measures.
