Great Lakes National Program Office Environmental Indicators

Biological Indicators

The health of organisms in the Great Lakes food web is critical to the health of the Great Lakes ecosystem.

Results from GLNPO's Biological Open Water Surveillance Program of the Laurentian Great Lakes 1999
The monitoring effort is focused on whole lake responses to changes in loadings of anthropogenic substances, so sampling is largely restricted to the relatively homogeneous offshore waters of each lake.

Benthic Community Health
Evaluating the health of the organisms that inhabit the bottom sediments of the Great Lakes and form an essential part of the food chain.

Biological Program - Species List
The Great Lakes National Program Office's Biology program has compiled lists of phytoplankton, zooplankton, and benthos species that have been found by the program in the Great Lakes, including both past and present species.
