Weed Warrior Charles

Weed Warrior Charles spends a lot of time removing invasive plants. After a career working to preserve the local ecology, Charles chose to spend his retirement also working to preserve the local ecology. Whether it is oriental bittersweet, garlic mustard, mile-a-minute, barberry or anything in between, Charles has educated himself and others to know the invasives of the northern region parks, especially, Little Bennett Regional Park.
