Wetlands and Aquatic Species

Wetlands are ecologically unique areas vital to the environmental and economic health of New England and New York State. They provide habitat essential to our fish and wildlife populations.

Some of our most popular recreational activities like canoeing and fishing, occur in wetlands. Wetlands provide open space, an important but increasingly scarce commodity in the Northeast.

Wetlands also purify water through the uptake and control of sediment and pollutants, protect lives and property by controlling floods, and buffer coastal areas from storm damage and erosion. Wetlands help to maintain stream and river flows during dry periods, thereby replenishing water supplies and maintaining aquatic habitat.

A threat to our wetlands and other aquatic ecosystems come from non-native plants, fish, and other organisms are a growing presence in the waters of New England and New York State. Whether introduced accidentally or intentionally, their sudden entry into complex, intricately interwoven ecosystems leads to unpredictable results. Those that cause harm are called aquatic nuisance species.

NEIWPCC’s New England Biological Assessment of Wetlands Workgroup coordinates with its national counterpart and many partners to monitor and assess the health of the region’s wetlands.

A separate workgroup is concerned with harmful algal blooms, which are potentially toxic and can foul water bodies and change ecosystems.

NEIWPCC works with our member states and other organizations to help study and preserve these vital areas.

Lakes Bioassessment

The New England Lakes and Ponds project report, circa 2010, evaluates the overall health of the region’s lakes and ponds.
