  1. MINNESOTA: DEVELOPING WETLAND BIOCRITERIA By: Michelle Parascando, AnetaGruchala, Marina Fernandes, Jason Patel, & Mike Wenk

  2. Notes • Purpose: To in the tools to assess wetland condition by studying vegetation and invertebrates in wetlands across a range of human disturbance. To develop two separate indexes of biological integrity for Minnesota depressional wetlands. • Assemblages: Macroinvertebrates and Vascular plants

  3. Project Descriptions • *Minnesota has been developing its wetland biological assessment programs since 1992.* • 1992- Small depressional reference wetland study >The initial research studied the quantity and quality of macroinvertebrates. (Macroinvertebrates of high quality wetlands.) • 1995- Expanded small depressional wetland study >Data was collected on a larger set of depressional wetlands for both macroinvertebrates and vegetation.

  4. Project Descriptions • 1999-Large depressional wetland study >Large depressional wetlands had been studied. Human disturbance has also been studied and how it affected the wetlands. • 2001-Statistical assessment of wetland monitoring methods >Nine wetlands had been studied to test the methods for invertebrate and vegetation IBIs with statistical procedures. • 2002-Citizen training • >A final guide for biological monitoring of wetlands by citizens will be produced by MPCA in 2002.

  5. Study Design • Wetlands had been studied for both macroinvertebrates and for vegetation. Macroinvertebrates: Animals without backbones. Vegetation: Plant-life • Human Disturbances had played a major role on the wetlands. (Stormwater and agricultural influences)

  6. Sampling • During sampling, macroinvertebrates had been studied by using the Dipnet and the activity trap method. • The Dipnetting method caught the greatest richness of inverterbrates while the activity trap captured the active swimmers and night-active predators. • Wetlands show clear patterns and show predictable reactions to human disturbances.
