Sinnemahoning Invasive Plan Management Area (SIPMA)

The Cameron County Conservation District entered into a Memorandum of Understanding (MOU) with and continued to support the Sinnemahoning Invasive Plant Management Area (SIPMA) and their efforts to control invasive plants in Cameron and neighboring Counties. Conservation District staff serve on the advisory committee, which includes many private landowners, PA Game Commission, PA Department of Conservation & Natural Resources (DCNR), Conservation Districts, PA Department of Agriculture, PennDOT, Western Pennsylvania Conservancy, US Forest Service, PA Fish & Boat Commission, and many other state and federal agencies as well as various timber management companies. SIPMA is lead by the program coordinator, Tanya Meyer.

The battle with invasive species is ongoing, and we are fortunate to have organizations, such as SIPMA, that are bringing awareness to the public and actively involved in removal of invasive species and re-establishment of native plants. For more information on SIPMA please visit
