3 Endangered Animals Found in PA Indiana Bat (Myotis sodalis) Pollution of the waters and deforestation to opening caves resulted in decreasing the main food source of the Indiana bat, mayflies. Also, gates were put up in caves to keep people out but disturbed the bats only habitat. Delmarva Fox Squirrel (Sciurus niger cinereus) Timber harvests continue to threat the Delmarva Fox Squirrel’s habitat. Eastern Puma (Puma concolor couguar) The Eastern puma is endangered due to hunting and trapping this species. Endangered Plants found in PA Virginia Spiraea Virginia Spiraea (Spiraea virginiana) Road construction, unmanaged recreational use of river corridors, industrial development, lack of watershed management, and uncontrolled development of river corridors all play a part in endangering this plant species. Northeastern Bulrush Northeastern Bulrush (Scirpus ancistrochaetus) This plant species depends on wetlands for its survival. Water pollution, excavation, and when dry, by off-road vehicle use will prevent the Northeastern Bulrush to die down leading it to a spot on the endangered list of plant species. 5 Of The Most Common Ways Invasive Species Come into our Country • Pet trade • Ships- can carry organisms living in water • Wood products- insects are able to get inside wood • Ornamental plant- some may escape into the wild and become invasive • Human transport 3 Invasive Animals in PA Zebra Mussel (Dreissena polymorpha) The Zebra Mussel is native to the Black Sea. What are some problems the Zebra mussel causes? It causes threat to biodiversity by causing turf wars which will lead to the loss of native mussels, disrupt food chains, and decrease biodiversity in our watersheds. Secondly, they cause health risks by passing on contaminates up the food chain. Lastly, they will cause economic costs by clogging intake pipes in facilities that provide water and power to local communities. This mussel will count down the population of pearly mussels. 3 Invasive Animals in PA Rusty crayfish (Orconectes rusticus) The rusty crayfish is native to the Ohio River Basin. The crayfish causes problems like displacing native crayfish with their aggressive personalities. They also will destroy aquatic plant beds and affect habitat like reduction in fish production. The rusty crayfish works as a scavenger and also provides food for large fish, raccoons, turtles and herons. 3 Invasive Animals in PA 2 Invasive Plants found in PA Kudzu (Pueraria lobata) The kudzu is a plant native to Asia. Its niche is to reproduce. The kudzu causes problems like covering them under a blanket of leaves causing them to degrade and die. 2 Invasive Plants found in PA Amur Maple (Acer ginnala) The Amur maple native to Japan, Korea and China. The Amur causes problems like maple will cause other surrounding plants from growing. Its niche is to provide shelter, shade and beauty.
