Nearshore glri 10

  1. 1. Nearshore and Non-Point Source Pollution funded by the Great Lakes Restoration Initiative Progress toward restoring the Great Lakes has been significantly undermined by the effects of non-native aquatic, wetland, and terrestrial invasive species. More than 180 aquatic nuisance species (ANS) now exist in the Great Lakes. The most invasive of these - including the well known zebra mussel - reproduce and spread, ultimately degrading habitat, out-competing native species, and short-circuiting food webs. Without forecasting the arrival and bioeconomic impact of nonindigenous species, natural resource management cannot cost effectively respond to current invasions or prevent future invasions.Indicating Land Use and Improving Coastal andAgricultural Tipping Points Human Health and Beach ForecastingCommunities need to know at what point theecosystem will take a turn for the worse.
