On June 4, the community and Rockline Industries worked together to clear invasive buckthorn from GLC's Grasshopper Hill Preserve. Common Buckthorn is a common (no pun intended) woody invasive species in Wisconsin that outcompetes native vegetation for resources, and can completely degrade habitat. At Grasshopper Hill, the buckthorn created thick walls all the way up to the edge of the trail in some areas! While there is a lot more to do, the volunteers worked hard to cut and treat as much buckthorn as they could. We even found a few smaller native trees underneath, which now have room to grow!
