Wind Cave National Park in South Dakota
At the Fund, we work to protect America’s favorite places and in 2011 we protected more than 5,500 acres at Wind Cave National Park in South Dakota. Considered a sacred place by the Lakota, Wind Cave is one of the world's longest and most complex caves and is home to one of America’s most ecologically-significant bison herds. The park now features more than 30,000 acres of mixed-grass prairie and ponderosa pine forest that provides important habitat and an amazing outdoor experience for visitors.





This iconic region has long sustained both wildlife and thriving communities but sprawl and land sales increasingly threaten this rare landscape. The Fund has, since 1985, joined with public agencies, private land trusts and landowners to safeguard nearly 360,000 acres of recreation areas, wetlands, working forests and wilderness in the Upper Midwest.
Since 2001, we’ve helped the Milwaukee Metropolitan Sewerage District fight flooding by managing “Greenseams,” a program that has protected more than 2,000 acres of key lands containing water-absorbent (hydric) soils. More than a million people live and work in the Milwaukee metro area—many in flood prone neighborhoods. As a long-term approach to flood management, Greenseams is an innovative program that uses land conservation as a tool to safeguard the community and its water supply.
The Fund is helping to implement the Ann Arbor Greenbelt Initiative, a far-reaching project designed to protect and link city parks, natural areas and working farms throughout the city, while curbing the growth and effects of sprawl.
