DESCRIPTION
Invasive, Endangered, and Reintroduced Species of Pennsylvania By: Colleen Smith. What is an endangered species? An endangered species is a group of organisms who run the risk of becoming extinct. 5 Most Common Reasons for Endangerment: Habitat Destruction Introduction of Exotic Species - PowerPoint PPT PresentationTRANSCRIPT
3 Endangered Animals Found in PA
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.
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.
Endangered Plants found in PAVirginia 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 (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 PAZebra 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 PARusty 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.

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 PAAmur 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.
