SPECIES OF PENNSYLVANIA
ENDANGERED SPECIES• An animal or plant species that has very
few organisms and can become extinct. • Usually happens because of habitat
destruction, introduction of exotic species, unregulated illegal hunting, competition, and disease.
WHAT CAN WE DO TO PREVENT ENDANGERMENT?One thing we can do is stop using pesticides like DDT in
foreign countries. The Endangered Species Act protects fish, plants, and other wildlife. We can also create more National Parks and nature reserves.
ENDANGERED ANIMALS IN PENNSYLVANIA
The Rough Pigtoe is endangered because of the loss of its habitat due to dams and the overflow of water.
Indiana Bats are endangered because there aren’t enough caves. Other things that cause them to be endangered are pesticides and a disease called White Nose Syndrome.
The Eastern Puma is endangered because of hunting, loss of habitat, and a shortage of food and prey.
ENDANGERED PLANTS IN PENNSYLVANIA
The Small Whorled Pogonia is endangered because of urban development, which is destroying their habitats.
The Northeastern Bulrush is endangered because of habitat modification and destruction.
SPECIESNative: A plant or animal that normally lives and thrives in an
ecosystem.
Introduced: A species that does not usually live in an area but is brought there by humans.
Invasive: A Species of plants or animals that is non-native to the environment, whose introduction may cause economic or environmental harm.
INVASIVE SPECIES AND THEIR ENVIRONMENT
Most Invasive Species get to a new environment because of humans. Some are get here naturally.
• To help pest control• Released from captivity• Ballast water released from ships• Ornamental Purposes• Used for hunting and fishing game
How They Affect The Environment• displace native species• alter ecosystem processes• reduce native wildlife habitat• reduce forest health and productivity
NORTHERN SNAKEHEADScientific Name: Channa Argus• This fish is native to China, Korea, and Russia and is used in
rice farming as a source of food to the farmers and as a predator for pests.
• It can move from location to location on land and survive if buried in mud.
• It can wipe our a small pond or stream ecosystem. • It eats a variety of native fish, and they have no natural
predators.
ROUND GOBYScientific Name: Neogobius Melanostomus• This fish is native to the Black and Caspian Seas in Europe. • Can hunt in total darkness which makes it easy for it to find
prey without it finding them. • Can survive long, awful winter conditions and hot summer
conditions. • It is a very aggressive bottom feeder which means it
competes with other native fish and wipes out other bottom feeders.
DOMESTIC DOVEScientific Name: Columbia LiviaThis bird is native to many different parts of Europe. • Source of food all over the world. • Lives near buildings and farms• It carries Exotic Newcastle Disease which can be spread
and endanger human health• Droppings do much damage such as kill vegetation and
food sources. They also destroy and damage buildings
AMUR MAPLE
Scientific Name: Acer Ginnala This tree is native to Russia and China.• Very tolerant to many different environmental factors. • Is used as an ornamental tree during summer time. • It displaces native vegetation and outcompetes native flora
because of it’s environmental tolerance and beauty.
CHOCOLATE VINEScientific Name: Akebia QuinataThis Vine is native to Japan• can be used to treat cancer and fungi infections• threat to native flora because it is very dense and can
outgrow native plants• Produces small edible fruits
REINTRODUCED AND EXTIRPATED SPECIES
Reintroduced: a release of species from captivity or other areas where the species can survive back into the wild.
Extirpated: a species that no longer exists in the wild in a certain area but can be found elsewhere.
REINTRODUCED SPECIES IN PENNSYLVANIA
ROCKY MOUNTAIN ELK They released 177 Elk from South Dakota and Wyoming into Pennsylvania because of the low elk population in the state. They then became known as the Rocky Mountain Elk.
