Outreach Publications

The Wildland Weed Management project has developed factsheets and bulletins providing information on elements of habitat management, specific recommendations for invasive plant species control, and guidance on the use of herbicides in wildland settings.

Invasive Species QuickSheets

QuickSheets are two-page documents developed with PA DCNR-State Parks to provide specific control recommendations for the most common invasive plant species in natural areas. The audience for these sheets is natural resource professionals, who would have access to the equipment and materials described.
