 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. Without WNS With 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: The plant is endangered because of habitat destruction.

 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

 Zebra Mussel  Scientific name: Dreissena polymorpha  Originated: Asia  Niche: To dig holes in rocks for homes. (for both)  Problems: No predators and live in pipes so they become blocked

 Asian Tiger Beetle  Scientific Name: Aedes albopictus  Originated: Southeast Asia  Niche: Adults are predatory insects, and larvae sedentary predators  Problems: Eat blood of larger species

 Sea Lamprey  Scientific Name: Petromyzon marinus  Origin: Atlantic Ocean and Lake Ontario  Niche: A parasite (for both)  Problems: Kills many fish

 Norway Maple  Scientific Name: Acer Platanoides  Origin: Europe  Niche: Reproduce winged fruits (samaras) that are taken away in the wind to disperse  Problems: Population increases fast, because seeds have a small amount of requirements to germinate.

 Kudzu  Scientific Name: Pueraria lobata  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
