Has a New Pathway for Increased Mercury in Fish Been Found?

There is growing evidence that zebra mussels may be affecting the level of mercury in fish tissue by altering contaminant cycling in inland lakes. While the mechanism of this increase needs to be further studied, it likely means that fish consumption advisories will increase for those lakes invaded by zebra mussels.

Prairie Pothole Wetlands: Small Basins, Big Impact

The benefits of prairie wetlands extend far beyond wildlife. These wetlands filter pollutants and excess nutrients from agricultural and urban runoff, trap sediment, recharge groundwater, and store floodwater.

The Importance of Fish for Native Freshwater Mussel Reproduction

To reproduce, freshwater mussels rely on fish to carry their young into new areas and disperse them when they are old enough. By conserving suitable fish habitat, it also allows us to indirectly conserve mussels by providing necessary resources for mussels to reproduce.

The Importance of Wetlands in Winter

Drive by a wetland in the dead of winter and it may look like a shut-down ecosystem, patiently waiting for spring to return. But that is simply not the case. While winter may present its own challenges, life goes on and wetlands play an important role.

The Importance of Riparian Areas

Riparian areas occur along streams, rivers, wetlands, lakes, and shorelines and can be considered the last line of defense before pollutants enter a body of water. Learn about the many benefits these areas offer and the programs available to support their conservation.
