Area History
Historical Prologue of Our Region – Southwest Wisconsin
Before Euro-American settlement the Landscape was dramatically affected by Native American culture and their activities. Native Americans occupied western Wisconsin since the last glacial period, utilizing the abundant food resources of the area, cultivating crops on the fertile floodplains, and building settlements on higher landforms. Fires were set by Native Americans to aid in hunting and to provide habitat for the game they desired and plants they used. These fires prevented forests from expanding and kept the landscape in prairie, oak savanna, and open oak woodland. A map of southwestern Wisconsin published by Chandler in 1829 states that “not more than a tenth is covered by timber in detached groves, the remainder being prairies” (Schorger 1954). When European settlers arrived in the early to mid-1800s, fires were stopped and forests quickly expanded. By 1854, Daniels (1854) stated only one third of southwestern Wisconsin was prairie. He attributed this rapid change from prairie to timber to the cessation of fires and rapid growth of young trees on the open prairie.
Land Use Impacts
Historical impacts – (excerpted and paraphrased from the: “State of the Bad Axe-La Crosse Basin Report” 2002). There have been dramatic changes in the land use and land cover in this Landscape. Settlers plowed the prairies on the ridge tops and valleys for farmland, cut trees on the steep slopes for building homes and barns, and grazed the slopes with cows. The Landscape went from a primarily open structure of prairies and oak savanna at the time of Euro-American settlement to the current patchwork of agricultural fields on the ridges and valleys and second growth forests on the steeper slopes and other places that could not be tilled. Less than 0.1% of the prairies and oak savannas remain today.
During and after settlement most of the area was farmed resulting in large-scale soil erosion and flash flood events. Crop fields were mostly rectangular on this highly dissected landscape, and plowing was often done up and down slopes. Steep wooded slopes that couldn’t be farmed were grazed by cows compacting the soil and removing the under story plants that prevented runoff. Millions of tons of topsoil moved from hilltops and hillsides to valley floors. An average of 12 to 15 feet of topsoil was deposited in the valley floors in the Bad Axe-La Crosse Basin, burying roads and bridges. Deep gullies were common where water washed away the soil. By the 1930s, after nearly eighty years of cultivation and grazing, virtually every rainstorm resulted in flash floods. By this time, farming in the Bad Axe - La Crosse River Basin developed into a frustrating venture with every new rainstorm washing away valuable crops, pasture and soil. The once crystal clear streams which held brook trout were now shallow, wide, warm and full of silt. The tons of sediment that reached the valley floor buried many springs and seeps, causing many perennially flowing streams to become intermittent, flowing only after rainstorms. Streams became braided meanders with their channel lost to the massive amounts of sediment now in the valley. In-stream fish habitat was lost, and the cold water brook trout were replaced by warmwater species such as suckers, carp, chubs and other minnows.
In 1934, the Federal Soil Erosion Service launched the Coon Valley Erosion Project in the Coon Creek Watershed. Men from the newly founded Civilian Conservation Corp (C.C.C.) planted trees, fenced livestock off of steep slopes, reconfigured fields to follow the hills’ contours, planted grassed waterways, and stabilized gullies. Efforts to restore streams were also attempted by adding wood and rock deflectors to force floodwaters away from streambanks toward the stream's center, and planting vegetation on streambanks. These land management practices were successfully adopted and most are still in use today.
Even after the various conservation measures, the Landscape was degraded, and flash floods continued to damage land and property in the basin. From the 1940s to the 1960s, farms on marginal land in the basin did not succeed, and the land reverted back to more natural conditions. In the 1970s, many farming operations went deeply into debt, overvalued land prices fell, and interest rates remained high. In the early to mid 1980s, many producers were forced to financially dissolve their farms. Large amounts of farmland were purchased by hobby farmers who were not interested in raising livestock or growing crops as their source of income, and these farms reverted to natural vegetation.
The Food Security Act of 1985 required compliance with farm specific conservation plans in order to receive any kind of government subsidy. From 1983 to 1988, land under conservation tillage in the area increased over 700%. The Conservation Reserve Program (CRP) was an incentive to remove highly erodible land from crop rotation and replace it with perennial vegetative cover.
Conditions have improved with these conservation actions. Infiltration of rain and snowmelt into the soil has reduced runoff. Conservation practices such as contour farming have reduced soil erosion. CRP has taken highly erodible land out of crop production. Streams are recovering, many once again becoming narrow, deep, and cold. The Landscape still has the highest percentage of southern forest types in the state and has many rare and significant features. However, the landscape is dramatically altered from its original condition; for example, millions of tons of soil were permanently relocated from hilltops and hillsides to other areas such as the valley floor
Current impact - Current disturbances in the Landscape are largely due to human activities, primarily agriculture, timber production and harvest, and cessation of fire. Human disturbance also includes the long-term conversion of land to houses, roads, agriculture, impoundments, and utility corridors.
In Freeman Township, the frequent use of “prescribed” fire continued long after it stopped in many other areas of western Wisconsin. Farmers understood its value for keeping brush out of pastures, stimulating and increasing the nutritional value of pasture plants, and in some cases “just to get rid of the rattlesnakes”. Evidence of this is commonly found in the form of fire scars on the uphill side of trees in many areas of the township. Fred Hogan of Lansing IA remembers “the river bluffs on the Wisconsin side of the river burning every year” (Fred Hogan personal communication) as a young man. Jake Sandry of DeSoto stated “the river bluffs always got burned, sometimes being lit by the Native Americans that lived just south of town” (Jake Sandry-personal communication). The fires set by locals up into the 1960’s helped maintain some of the rarest habitat in the United States; prairie and oak savanna, and helped to give our township the unique opportunity to restore and maintain these types that is nearly unmatched.
