Over seventy years ago, Dorothy and Gordon Kummer of Milwaukee purchased some rural acreage southwest of Rhinelander, Wisconsin, and began a remarkable legacy of stewardship and conservation education that continues today.
They called this land “Treehaven”, and under their care and supervision, the Kummers planted nearly 140,000 trees on the property, ultimately creating one of the nation’s finest examples of sustainable forest management by a private landowner. Following Gordon Kummer’s death, Dorothy remarried a Milwaukee school science teacher named Jacque Vallier, also an avid conservationist.


The Valliers eventually donated the land to the University of Wisconsin-Stevens Point, which helped mold Treehaven into the premier natural resources education and conference facility it is today.
