Great Lakes Environmental Indicators
This site contains documentation and datasets related to the Great Lakes Environmental Indicators project. GLEI I ran from 2000-2005 and GLEI II from 2010-2015. The overall goals of GLEI were to:
- quantify anthropogenic stress in watersheds across the Great Lakes basin
- develop biotic indicators of stress across a series of taxa: amphibians, birds, diatoms, invertebrates, fish, and vegetation
- identify potential mechanistic indicators between stressors and their effects
- define what constitutes reference and degraded coastal ecosystems
- deliver guidelines on the use of indicators to management agencies and stakeholders, including scale of application, sensitivity, ease of collection, analysis and communication, and cost effectiveness.
Data included on this site comprise GIS layers on watersheds and segmentsheds, as well as biological and water quality data from GLEI sample sites.
The final report for GLEI can be found here: https://issuu.com/naturalresourcesresearchinstitute/docs/glei_ii_final_report
