The Washington County Conservation Board is having their annual Marr Park Night Prairie Burn. Topics to be discussed include the role of fire in the prairie ecosystem, and the tools and methods involved during a controlled burn. Naturalist Pam Holz says it’s a management tool for maintaining prairies. She says it burns off dead grasses, woody and cool season invasive plants, and leaves room for the new growth of spring. Holz also says seed production will be increase as a result. The public is invited to the burn Monday, April 5th, at 7pm at Marr Park.
