“Many rare habitats on museum preserves are now free of invasive plant species, due to the expert weed control performed by Crowleys. One of the most spectacular restoration efforts, performed by Crowleys at the Museum’s Singer Lake Bog in 2001, completely removed more than an acre of canary grass. In addition to restoring a population of the State Threatened kelled bur-reed and another rare plant, never before seen in Summit County, silver sedge, emerged from the dead canary grass thatch one year after Crowleys sprayed the canary grass. Many stands of canary grass were present along the two miles of shoreline within the Singer Lake Basin when the Museum began contracting Crowleys in 2001. Canary grass and many other invasive plants such as tree of heaven and hybrid cattail are nearly absent from the Singer Lake Bog today. Crowleys removed an outbreak of garlic mustard, at the Museum’s Grand River Terraces Preserve in 2001 and 2002. Because the garlic mustard was stopped before it entered the forests at the Grand River Terraces, the entire 880-acre preserve, is essentially free of garlic mustard at this time.”

“Crowley’s Weedman has become an integral part of our company. Their
knowledge and commitment to environmental stewardship – coupled with their
outstanding service, has been a tremendous asset to Best Sand Corporation in
our efforts to rid our plant of phragmites and other invasive species.
Crowley’s has helped us to develop both short-term and long-term plans – and
has provided valuable education in non-herbicidal methods to control
phragmites growth.”
