  1. Species of Pennsylvania By Mackenzie Rodgers

  2. Endangered Species • Definition:a plant or animal species existing in such small numbers that it is in danger of becoming extinct, especially such a species placed in jeopardy as a result of human activity. • 5 Most Common Reasons For Endangerment: • Overexploitation • Introduction of Exotic Species • Habitat Destruction • Competition • Disease

  3. Prevention of Endangerment • Protect habitat • Recycle and buy sustainable products • Minimize use of herbicides and pesticides

  4. Endangered Animals in Pennsylvania • Eastern Puma: (Puma concolorcouguar) • Indiana Bat: (Myotissodalis) • Short-Eared Owl: (Asioflammeus)

  5. Endangered Plants in Pennsylvania • Northeastern Bulrush: (Scirpusancistrochaetus) The Bulrush is endangered because their habitat is threatened by water level, pollution, and excavation. • Virginia Spiraea: (Spiraeavirginiana) Endangered because it is at risk to alterations of stream-flow patterns, road construction, and industrial expansion

  6. Native, Introduced, and Invasive Species • Native Species: that normally lives and thrives in a particular ecosystem. This can include any species that developed with the surrounding habitat, and can be assisted by or affected by a new species. • Introduced Species: a species that does not occur naturally in a given area, though has been introduced to it • Invasive Species: a species that does not naturally occur in a specific area and whose introduction does or is likely to cause economic or environmental harm or harm to human health.

  7. Common Ways Invasive Species Enter Our Country • Soil brought in with plants • Abandoned pets • Water discharged from ships • Peoples’ clothing • Imported goods

  8. Ways They Effect Our Environment • Reduce native wildlife habitat • Reduce forest health • Change ecosystem processes • Relocate native species

  9. Invasive Animals In Pennsylvania • Brown Marmorated Stink Bug:(Halyomorphahalys)is native to China, Japan, Korea and Taiwan. It was accidentally introduced into the United States, with the first specimen being collected in September 1998.The brown marmoratedstink bug is considered to be an agricultural pest and by2010-11has become a season-long pest in U.S. orchards. • Asian Tiger Mosquito:(AedesAlbopictus) It is native to the tropical and subtropical areas of Southeast Asia; however, in the past couple of decades this species has invaded many countries throughout the world through the transport of goods and increasing international travel. This mosquito has become a significant pest in many communities because it closely associates with humans (rather than living in wetlands), and typically flies and feeds in the daytime in addition to at dusk and dawn. • Emerald Ash Borer:(Agrilusplanipennis) is a green beetle native to Asia. In North America the borer is an invasive species, highly destructive to ash trees in its introduced range

  10. Invasive Plants In Pennsylvania • Kudzu:(Puerarialobata)It is a climbing, coiling, and trailing vine native to southern Japan and southeast China. It is a weed that climbs over trees or shrubs and grows so rapidly that it kills them by heavy shading • Princess Tree:(Paulowniatomentosa) it is native to central and western China, but invasive in the US. It grows to 10–25 m tall, with large heart-shaped to five-lobed leaves 15–40 cm across, arranged in opposite pairs on the stem. On young growth, the leaves may be in whorls of three and be much bigger than the leaves on more mature growth

  11. Reintroduced Species • The act of introducing something again, especially the release of animals from captivity into the wild

  12. Extirpated Species • A species that has been destroyed or removed completely from a particular area, region, or habitat. The species, however, may exist elsewhere, e.g., in a zoo or aquarium

  13. Reintroduced To Pennsylvania • Elk:(CervusCanadensis) • Why:The elk were over hunted, last one shot in 1867 • When:1913-1926 • How: the Pennsylvania Game Commission released 177 elk from South Dakota and Wyoming into state forest lands in Pennsylvania. The introduced Rocky Mountain Elk (Cervuselaphusnelsoni) is not the same subspecies as the original Eastern Elk (Cervuselaphuscanadensis), which is thought to be extinct. However, both are of the same species and share ecological niches
