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.

The kudzu causes
problems like
covering them under
a blanket of leaves
causing them to
degrade and die.
2 Invasive Plants found in PA

(Acer ginnala)
The Amur maple native to
Japan, Korea and China. The

maple will cause other
surrounding plants from
growing. Its niche is to
provide shelter, shade and
