Ottawa National Forest

Survey Work 2012-2014, 2016

Rare and invasive plant surveys were conducted on the Ottawa National Forest in Michigan's Upper Peninsula during the field seasons of 2012, 2013, the spring of 2014, and in 2016.

In 2012, we surveyed 10,000+ acres worth of stands in Ontonagon County, finding many new rare and invasive plant sites. In 2013 through the spring of 2014, we surveyed 15,000+ acres in Gogebic County, again with success in finding rare and invasive plants. In 2016 we surveyed around 5,000 acres in Baraga and Houghton counties.
