Water quality condition monitoring — Long-term wetland monitoring

Since 1995, the Biological Monitoring Unit has been revisiting a small set of depressional wetlands. All of these sites are located within relatively stable land use settings—broadly categorized as urban, agricultural, or natural. Information gained from these sites is used to help determine whether any large-scale factors such as changes in climate patterns or atmospheric deposition are affecting the condition of Minnesota’s wetlands. These sites are monitored over time using plant and macroinvertebrate IBIs to look for trends in the indicators. If indicators exhibit a similar pattern (increasing or decreasing) from year to year across the long term monitoring sites — then regional-scale factors in addition to any site specific factors may be influencing the condition of these sites.

For more information on the purpose and rationale for long term monitoring of wetlands in Minnesota see the following fact sheet:

Monitoring sites

A total of 18 long term depressional wetland monitoring sites have been established throughout the state. Six sites are located within each of Minnesota’s three major ecoregions and these are monitored approximately every three years. Within each ecoregion sites have been located in areas representative of least-disturbed conditions (= natural) as well as agricultural and urban settings. These sites are semi-permanent to permanently inundated depressional wetlands that have a fringe of emergent vegetation as well as floating-leaved and submerged aquatic plant communities (i.e., marshes).

For more information about depressional wetland assessment methods and sampling protocols please visit the wetland monitoring and assessment page.
