Healthy Illinois Wetlands Support a Healthier Mississippi River

Illinois lawmakers have a possibility to cut back flood threat, shield water high quality, and preserve important wildlife habitat by restoring and defending wetlands. 

Many wetlands in Illinois have been misplaced over time, affecting the birds and communities that depend on them. The Wetlands Protections Act would create a complete state allowing program that, aside from exempt actions like regular farming actions, would require permission previous to modifying or filling wetlands. This might assist keep away from impacts to the 72% of Illinois’s 981,000 acres of remaining wetlands which are liable to improvement or drainage. The state could be compensated for any impacts which are unavoidable; these funds may then be used for future restoration actions. 

Passage of the Wetlands Safety Act could possibly be a part of a broader effort to extend state wetland protections and restoration efforts. For instance, in Wisconsin, the state legislature licensed an illustration mission to check pure flood threat discount practices, comparable to wetland restoration tasks, to mitigate flood impacts in flood-prone areas of Ashland County, WI. The mission proved to be so profitable that the Wisconsin legislature adopted it up with the creation of a Pre-Disaster Flood Resilience Grant Program. Illinois may observe the identical formulation to create its personal pre-disaster flood resilience grant program to assist voluntary wetland development and restoration tasks throughout the state.  

With the dangers of additional wetland loss resulting in better hurt to hen and human communities in Illinois and downstream on the Mississippi River, efforts to guard and broaden wetlands are extra essential and pressing than ever. Illinois and different states missing complete wetland protections ought to take steps now to set up packages and safeguards to preserve these vital habitats. 

The Mississippi River was traditionally characterised as a wealthy mosaic of braided channels, islands, lakes, and wetlands supporting various plant and animal communities. For the reason that 19^th century, tens of millions of acres of wetlands have been misplaced all through the ten states of the mainstem Mississippi River, in addition to the river’s 1.2 million sq. mile basin. As European settlers moved westward throughout the USA, they reworked a lot of the Mississippi River Basin from forests, wetlands, and prairies to row crops, pastures, and cities. Many wetlands have been drained or plowed beneath for agricultural manufacturing, streams and rivers have been straightened to enhance navigation and planting and harvesting effectivity, and the rise in impervious surfaces like roads and rooftops decreased water infiltration throughout the panorama, growing overland runoff.  

Corn Belt states have skilled a few of the largest losses of pre-settlement wetlands within the nation. Illinois, Indiana, Iowa, Missouri, and Ohio have misplaced greater than 85 p.c of their historic wetlands. These states now make investments tens of millions of {dollars} every year to stop air pollution, particularly nutrient and fertilizer air pollution, from coming into waterways that finally circulation to the Mississippi River and Gulf of Mexico. Wetlands present pure filtration that removes these contaminants, bettering and defending water high quality.  

Wetlands are additionally nature’s sponges. Only one acre of wetland, one foot deep, can retailer as much as 1.5 million gallons of water. By storing and slowly releasing water, wetlands cut back streambank erosion, recharge groundwater, and cut back flood injury. In contrast to conventional flood mitigation constructions, like levees and floodwalls, wetlands would not have costly repairs and restore prices following a flood occasion. A recent study discovered that each $1 invested in wetlands restoration in Ohio returned $8 to the general public.  

Along with defending water high quality and lowering flood impacts, wetlands present important habitat for birds. Roughly one-third of North American hen species, together with Bald Eagle, Nice Blue Heron, and Brown Pelican, use wetlands for meals, shelter, or breeding. Wetland-dependent birds within the Mississippi Flyway embrace cranes, grebes, herons, kingfishers, loons, owls, perching birds, pelicans, shorebirds, falcons, and waterfowl. They use wetlands for breeding and nesting, in addition to for relaxation stops throughout lengthy migratory journeys.  

Sadly, many of those vital habitats, particularly remoted wetlands, are liable to being misplaced as a result of they don’t seem to be protected. States have the regulatory authority and duty to guard wetlands. They will outline wetland protections and implement packages to assist wetland conservation and restoration. Illinois can do that in the course of the present state legislative session, beginning with the passage of the Wetlands Safety Act.
