Invasive, Endangered and Reintroduced Species of PA

By Nate Morgus

Endangered Species

• An endangered species is a species that is close to becoming extinct because it’s numbers are decreasing.

The most common threats to endangered species that lead them to be endangered are:•Habitat destruction•Over hunting•Pollution•Introduced (invasive) species•Disease

Prevention

• You can do some simple everyday things to help prevent endangered species.

Some of the best ways to help out are:•Recycle •Use less energy•Use products that are environmentally friendly•Help out to protect environments and ecosystems

Indiana Bat

Indiana bats are endangered for several reasons. The main ones being:• Hibernation disturbances• Starvation during winter

American Bittern

The American Bittern is endangered due to:• Loss of habitat • Destruction of breeding areas

Peregrine Falcon

Peregrine falcons are threatened because:• The pesticide

DDT

Bog Blue Grass

Bog blue grass is threatened by• Their habitats

being drained for agricultural or recreational purposes• Animal grazing• Overgrowth

Canada Spikesedge

Canada Spikesedge is threatened mostly in Pennsylvania due to habitat destruction.

Invasive species…

• Invasive species are species brought in to an area from somewhere else that take over an ecosystem or habitat.

• Native species are species that are native to a specific are and are not introduced.

• Introduced species are species that are taken out of their natural living area to a different area

How are invasive species are moved around ?

• Invasive species are brought in to area most commonly by humans

• Habitat restoration• Pest control • Fish stocking• Recreational activities

Invasive species negatively impact our environment

• Invasive species threaten native species• Decrease biodiversity• Alter the genes of species to make them more

susceptible to disease by interbreeding

Wild Boar• Sus scrofa Linnaeus• Wild boars are native to Eurasia • In their natural habitat wild boars

are predators but don’t usually eat meat.

• In their introduced habitat they are considered dangerous pests.

• The biggest problems with these boars are they can be viscous predators and have been known to attack animals such as dogs.

European Starling• Sturnus vulgaris• European starlings are

native to Europe• In their natural habitat

starlings are pest birds that roost where ever they can

• In their introduced habitat there is little to no difference

• Their droppings can have toxins that can kill fully matured trees

Emerald Ash Bore • Agrilus planipennis Fairmaire

• It is native to Asia

• In Asia and in America, they have killed tens of millions of trees.

• They are considered a pest wherever they are found.

• They will bore in to fully matured trees and lay their eggs in them and the young will eat the trees.

• These logs are often cut down and moved to other areas spreading this pest.

Reintroduced Species

• Any species that was at once gone from an area but was later brought back by humans or some other way are called reintroduced species.

Gray Wolf

• The gray wolf (Canis Lupus) was once extinct from Yellowstone National Park

• For 70 years there were no wolves in the entire park

• But in 1996 the first wolves were released in to the park thanks to biologists

• Now the gray wolf population is healthy in the park.
