By: Chadd Cummings 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 Endangered SpeciesEndangered Specie images Bog Turtle Wildlife Service Defintions of invasive, native, and introduced Invasive species and plants Definition Elk
