Endangered Species Segment Endangered species-any species of plant, animal, or other organism that is at risk of extinction because of a sudden rapid decrease in its population or a loss of its critical habitat. Reasons for extinction-Taking animals for profit, Hunting and trapping, Over harvesting, Introducing species, Destruction of habitat. Prevent extinction-Preserve habitats. PA endangered animal species- Eastern Puma:endangered due to hunting and destruction of habitat. Bald Eagle: endangered due to pesticides. Lynx:endangered due to hunting for fur and destruction of habitat. PA endangered plant species- Virginia Spiraea:endangered due to habitat loss because of alterations of stream flow patterns and other threats. Northeastern Bulrush:endangered due to destroyed/degraded habitat.

Invasive Species Segment Native Species-A species that occurs naturally with respect to s particular area, rather than a result by humans. Invasive Species-Animals, plants, and other organisms that are newly introduced into an area from another part of the world. Invasive species cause problems in their new environment Introduced Species-A species that humans have placed in an ecosystem or community, in which it does not occur naturally. Ways Invasive Species get into US-natural pathways, Human induced pathways, Intentional Introductions, Unintentional introductions, Animal induced introductions.

Invasive Species Segment (cont) Invasive Animal Species in PA- Asian Tiger Beetle:(Aedes albopictus)(Originated in Southeast Asia)(Feeds on blood of larger mammals)(Aggressive biters who occasionally caries diseases) Emerald Ash Borer:(Agrilus planipennis)(Larvae causes ash trees to die)(It feeds on ash trees)(Too many ash trees are dying)(originated from eastern Russia/northern China) Sirex Wood Wasp:(Sirex noctilio fabricius)(originated from europe and most of Asia)(Feeds on pine species of trees)(too many pine trees are dying)

Invasive Species Segment (cont) Invasive Plant Species in PA- Kudzu:(Pueraria lobata)(Originated from northern Asia)(Creates more kudzu)(overgrown in forest) Five-leaf Akebia:(Akebia quinata)(originated from central China to Korea and Japan)(Creates more Five-leaf Akebia)(overgrown in forests)

Invasive Species Pictures Sirex Wood Wasp Asian Tiger Mosquito Emerald Ash Borer Kudzu Five-leaf Akebia

Reintroduced/Extirpated Species Segment Reintroduced Species-A species released into the wild formerly inhabited by said species but has disappeared for a specific reason. Extirpated Species-A species that no longer exists in a certain country or area, but can be found else in the world. (extinct in a specific area) Reintroduced Species in PA-Beaver The Beaver has been extirpated in PA since about 1903. They were reintroduced in about 1917.
