 Climate Change
 Disease
Prevent Endangerment by:



Learning more about the Species
Being aware of possible environmental
problems
Creating Conservation groups or clubs
Indiana Bat

Reasons that Endangered: Cave Commercialism and
Improper Gating, Loss of Habitat, Insect pesticides,
Environmental Contaminates

Commercialism of Beaches, Dams flooding nesting
areas and making them too dry, Sensitivity to humans
causes them to abandon their nests, eggs being crushed
by humans, animals preying on the eggs

wetland habitats

alteration, only 3 populations in PA
Definitions
Native: Species that has been in an area for a
long time
Introduced: Species which is brought into a new
area
Invasive: A species whose introduction causes
environmental harm
5 most common ways invasive species come into the U.S. :
1. foreign ballast water
2. hidden in wood packing material
3. hidden in other vegetation via the nursery trade
4. hidden aboard ships
5. hitchhiking on other species
Negative effects on the environment:

shrubs and under-story trees, provides shade, shelter, and beauty
Problems it causes: out-competes native flowers, prevents
surrounding plants from growing, displaces native plant species
Definitions
Reintroduced Species: a species that is
reinstated into an area in which it was
established before but became extinct
Extirpated Species: a species that becomes
extinct from a particular area

At one time, elk were extinct in North America. In 19131927 elk were introduced to Pennsylvania and several
