
Definition: A species whose numbers are so
small that the species is at risk of extinction
5 Most Common Reasons for Endangerment
Overexploitation
Habitat destruction
Introduction of exotic species
Disease
Pollution
Indiana Bat:
The indiana bat population was killed mostly by
(WNS) White nose syndrome.
With WNS
Without WNS
Bog Turtle:
The bog turtle is endangered because of
habitat loss.

Piping Plover:
The piping plover is endangered because
of habitat destruction.

Northeastern Bulrush:
The plant is endangered because of
habitat alterations and destruction.

Small Whorled Pogonia:


Native Species: are species that have evolved in our
area and in similar habitats and were growing here
before the first European contacts with North
America.
Introduced Species: a species that humans have
placed into an ecosystem or community in which it
does not naturally occur.
Invasive Species: non-native to the ecosystem
under consideration and whose introduction causes
or is likely to cause economic or environmental
harm or harm to human health.


Colonists brought over animals
Brought over for biocontrol
Used as a pets
Unintentionally brought in
Carried by ships





Negative Impacts:
invading natural ecosystems and displacing
the native flora
Causes decreased biodiversity
May have competition with native species for
food
Invasive plants require the use of herbicides
for control measures, and may harm other
species

Origin: Asia
Niche: To reproduce
Problems: Kills and degrades other plants by
smothering them under a solid blanket of
leaves.

Reintroduced Species: Reintroducing wild
animals and plant species to their natural
habitat.
Extirpated Species: A species that has
become extinct in a given area.

Elk
Why: Unregulated hunting
When: Between 1913 and 1926
How: public support and participation
enabled the elk to stay protected
