BENEFITS OF INDIANA WETLANDS:  BENEFITS OF INDIANA WETLANDS Division of Fish & Wildlife Indiana Department of Natural Resources In the early 1800s, one-quarter of Indiana was covered by wetlands (5.6 million acres):  In the early 1800s, one-quarter of Indiana was covered by wetlands (5.6 million acres) After 150 years of land use conversion (4 generations), around 13 percent remained. :  After 150 years of land use conversion (4 generations), around 13 percent remained. WETLAND HABITAT PROTECTS RECREATIONAL AND COMMERCIAL FISHING IN INDIANA:  WETLAND HABITAT PROTECTS RECREATIONAL AND COMMERCIAL FISHING IN INDIANA Support of fisheries for 874,000 recreational anglers, who spent $519 million in 2001. 75 charter fishing guide businesses. 502 inland commercial fishing licenses and 1,782 net tags were sold annually yielding at harvest of 165,360 pounds of fish. Northern pike spawning sites are located in shallow flooded marshes associated with lakes and inlet streams. FISHING GENERATES INCOME FOR MISHAWAKA / SOUTH BEND:  FISHING GENERATES INCOME FOR MISHAWAKA / SOUTH BEND The St. Joseph River in South Bend and Mishawaka provides a unique trout and salmon fishery—and provides access to fish for medical research. Developed through a $15 million interstate effort that annually generates about $6 million in income to local communities. WETLAND HABITAT PROVIDES RECREATIONAL WATERFOWL HUNTING:  WETLAND HABITAT PROVIDES RECREATIONAL WATERFOWL HUNTING Supporting waterfowl for 19,000 licensed duck hunters and 2,500 fur trappers, who spent over $3 million in 2001. The Grand Kankakee Marsh was one of the largest freshwater wetland complexes in the US with 500,000 acres of prime waterfowl habitat. The North American Waterfowl Management Plan calls for Indiana to restore more than 47,000 acres of production habitat and 19,000 acres of migration habitat over the next 15 years. RARE WETLAND HABITATS HARBOR ENDANGERED SPECIES:  RARE WETLAND HABITATS HARBOR ENDANGERED SPECIES Over 60 rare and endangered species in Indiana are dependent on wetlands for some or all of their lifecycle. EPHEMERAL, OR SEASONAL, WETLANDS SUPPORT AMPHIBIANS AND REPTILES:  EPHEMERAL, OR SEASONAL, WETLANDS SUPPORT AMPHIBIANS AND REPTILES Ephemeral, or seasonal, wetlands are one of the most important and threatened habitats for amphibians and reptiles in the Midwest. A 2-acre ephemeral wetland pond at Lime Lake, Steuben County, is located in a former pasture, isolated from the larger lake by a gravel ridge. It is the only known location for Blanding’s turtles in the immediate vicinity. DUNE AND SWALE WETLANDS:  DUNE AND SWALE WETLANDS Complexes are located in NW Indiana. Sand ridges separate linear wetland swales, some of which are seasonally ponded. These wetlands are connected by subsurface water, which easily moves through the sandy substrate. Numerous rare species occur in this globally rare natural community. BOG WETLANDS:  BOG WETLANDS Bogs primarily occur in NW and NE Indiana Isolated wetlands that are very diverse in plant and animal life. They are also extremely rare in Indiana. Some are as small as one-quarter (0.25) acre in size. FENS AND SEEP WETLANDS:  FENS AND SEEP WETLANDS Largely restricted to the part of Indiana that was formerly glaciated, frequently on the central till plain. Sometimes all that remain of a formerly forested watershed. Harbor numerous rare species, including unique dragonflies which can only survive in a fishless habitat. KARST (SINKHOLE) WETLANDS:  KARST (SINKHOLE) WETLANDS These wetlands are located in the Karst Region (primarily found in five south-central counties). Rare nationally, typically less than 1 acre in size. Occur when sinkholes become plugged and fill with water. Deeper depressions harbor sinkhole ponds; shallow depressions produce “sinkhole swamps.” Many unusual and uncommon species occur in these wetlands. High quality examples are extremely rare, as most of the karst wetlands have been modified for use as livestock watering ponds. EPHEMERAL WETLANDS AND MANY RARE TYPES ARE NOT REPLACEABLE:  EPHEMERAL WETLANDS AND MANY RARE TYPES ARE NOT REPLACEABLE Location, location, location - Unique positions in the landscape provide the hydrology, soils, slope, sunlight, climate, and water chemistry that sustains rare types of wetlands. Ephemeral wetlands can sometimes be successfully restored with attention to detailed ecological requirements and availability of an amenable location. They have not been successfully created from scratch. WETLANDS PROTECT LIFE AND PROPERTY:  WETLANDS PROTECT LIFE AND PROPERTY Sediment filtration and protection of drainage ways. Flood control and water storage. Groundwater recharge. Slide15:  WETLANDS ARE VITAL FOR WATER QUALITY Natural removal of chemical pollutants including excess fertilizer and waste materials from lakes and streams. Natural wetland principles are used to create wetlands that treat nitrates, bacteria, and other contaminants. BY THE 1970s, LAKES AND RIVERS WERE MUDDY AND FULL OF ALGAE:  BY THE 1970s, LAKES AND RIVERS WERE MUDDY AND FULL OF ALGAE Murky water due to suspended silt and high phosphorus levels characterized Indiana lakes. Runoff of sediments and nutrients were contaminating lakes and reducing their worth for fish, wildlife, recreation, and property values. Many species of fish cannot tolerate muddy water with high nutrient loads. PRIVATE LANDS ASSISTANCE:  PRIVATE LANDS ASSISTANCE Most remaining wetlands are on privately owned land (80% in agricultural areas). Your tax dollars at work! Several agencies cooperate with the public to establish sound wetland conservation policy and restoration programs in Indiana. Federal: Natural Resources Conservation Service (NRCS) US Fish and Wildlife Service US Environmental Protection Agency State: Department of Natural Resources Department of Environmental Management Office of the Commissioner of Agriculture Soil and Water Conservation Districts Slide18:  AGRICULTURE AND WETLANDS Agricultural production depends on a healthy environment. Farmers participate in wetland conservation programs with state and federal assistance. INDIANA FARMERS PRODUCE DUCKS:  INDIANA FARMERS PRODUCE DUCKS Farmers allow land to flood between crop seasons, providing wetland areas for wildlife. Over 30,000 acres enrolled in federal habitat conservation programs such as the Wetland Reserve Program (WRP). INDIANA FARMERS PRODUCE FISH:  INDIANA FARMERS PRODUCE FISH In regions where half the farmland was in conservation tillage, lake water clarity was over 8 ft compared to only 3.5 ft in regions with lower use of conservation practices. Over 1,660 landowners use federal EQIP funds to protect water quality in farmed areas. Slide21:  In 10 years, over 35 wetlands reconstructed at inlets to remove sediments, nutrients, and other contaminants from downstream lakes. - Lake Wawasee - Tippecanoe - Koontz Lake - Gilbert Lake - Juday Creek - Shipshewana - Bruce Lake - Flint Lake, etc. LAKE RESIDENTS RESTORE WETLANDS WITH IDNR LARE FUNDS Lake Maxinkuckee Wetlands LOCAL GROUPS: DUCKS UNLIMITED:  LOCAL GROUPS: DUCKS UNLIMITED National DU officers live in Marshall County! Statewide achievements: -- 91 projects -- 5,811 wetlands acres -- $1.9 million invested -- 683 upland acres LaPorte: Bernacchi Marsh, 165 acres - $73,000 Lake: Hog Marsh, 620 acres - $100,000 Goose Lake Wetlands, 520 acres Steuben: Cedar Lake, 530 acres - $130,000 Crane Marsh, 22 acres - $20,500 Marshall: Heins Marsh, 45 acres - $19,300 Starke: Round Lake - $20,000 Turkey Foot Wetlands, 102 acres LaGrange: Pigeon River - $80,000 Slide23:  LOCAL GOVERNMENT PROJECTS County surveyors in St. Joseph and Steuben counties are restoring wetlands and streamside vegetation to reduce flooding and the need for removal of sediments from drainage ways. Federally endangered mussels in the Tippecanoe River need wetland filters. Slide24:  Facilitated by DJ Case & Assoc of Mishawaka. Statewide plan completed in 1996. Adopt-A-Wetland and Public Outreach guides. Support for 35 local wetland land trusts. Pilot wetland classification and mapping. Meetings and conferences for agency, industry, and environmental representatives. INDIANA WETLANDS CONSERVATION PLAN BY THE 1990s, WATER QUALITY HAD IMPROVED SIGNIFICANTLY:  BY THE 1990s, WATER QUALITY HAD IMPROVED SIGNIFICANTLY Monitoring by IDEM shows a tight relationship between lake water quality and regions of the state where farmers have improved their soil and water conservation practices. Over 75 percent of the lakes in some Indiana regions have improved in water quality within the last 20 years. BILLBOARD ALONG THE HIGHWAY…:  BILLBOARD ALONG THE HIGHWAY… PROTECT YOUR INVESTMENT!:  PROTECT YOUR INVESTMENT! Gains of the past 30 years since the signing of the Clean Water Act. Better scientific understanding of wetland functions and values. Increasing emphasis on recreation and quality of life in the “new economy.” Demand for and value of waterfront property provides local revenue.
