Removal of Buckthorn, An Invasive Species:

Buckthorn is an invasive species that has taken over much of Sanctuary Woods remnant oak savanna and interrupted the regeneration cycle of the old-growth forest. In 2019 Milwaukee County Parks helped facilitate three buckthorn remediation projects in a section of Sanctuary Woods. Several Boy Scouts formed the core-group, and was joined by dozens interested community members. See the good work started in 2019 here:

In 2020, a Boy Scout Eagle project will focus on further buckthorn remediation.  Hoppe Tree Service has generously agreed to partner with Friends of County Grounds Park in a more extensive remediation project.  We appreciate their partership to improve this special place, support our community, and support our youth.
