Endangered Species What is biodiversity? Why is biodiversity important? What are the five major threats to biodiversity? Treaties and legislations What efforts are being made to slow the loss of biodiversity? Endangered Species Teacher Packet • Background information • List of Endangered Species at Woodland Park Zoo • List of Species Survival Plans at Woodland Park • • • • • Zoo List of Species of Concern in Washington Vocabulary Resources Activities Plant and Animal Fact Sheets What does it mean to be endangered? a species that is in danger of extinction if nothing is done to prevent it Biodiversity What is biodiversity? Biological diversity or biodiversity: • diversity of species • diversity of genes within species • diversity of ecosystems on the planet Why is biodiversity important? • • • • • • Aesthetic value of biodiversity Moral responsibility to protect biodiversity Species interrelationships: the web of life Medicinal value of genetic diversity Agricultural value of genetic diversity Ecosystem health maintained by biodiversity Threats to Biodiversity Threats to biodiversity Scientists agree that the following five factors are the major problems contributing to the current loss of biodiversity: 1. habitat destruction 2. introduced species 3. pollution 4. overexploitation 5. population growth Habitat Destruction • Demand for land: agriculture, development, extraction of natural resources development includes roads, buildings, homes extraction of natural resources includes mining, logging, hydroelectric power (dams) • Habitat destruction can result in habitat fragmentation populations isolated from one another inability to access resources to fulfill basic needs Habitat fragmentation Pygmy rabbit: a species affected by loss of sagebrush steppe habitat in eastern Washington Washington Dept. of Fish and Wildlife Lion-tailed macaque: a species affected by habitat fragmentation in the Ghat Mountains of India Ghat Mountains Photo by Gerry Ellis Introduced Species • Introduced species have been moved from their native habitats to new habitats - usually by humans, accidentally or intentionally. • Some introduced species become invasive in their new habitats = successfully reproduce and spread Introduced Species • Invasive species can have a multitude of impacts: prey on or outcompete native species ecosystem impacts (change hydrology, encourage fire) agricultural/natural resource losses (pests, diseases) • Invasive species, once established, are very difficult to eradicate = prevention of invasions is key Western pond turtle: populations have declined, in large part due to predation by introduced bullfrogs Photo by Kate Slavens Pollution: air, land and water • Industrial • Agricultural • Household • Noise, light and heat pollution • Global climate change Biomagnification Overexploitation • Unsustainable trade live animals/plants pet trade parts/products medicinal use, adornment, decoration • Unsustainable hunting and harvesting of animals and plants for food Human population growth • Threats are all intensified by the rapid growth of human populations • However, it is not population growth alone that has these impacts: (population) (consumption) (impact) Lifestyle Choices Endangered Species Treaties and Laws IUCN • • • (World Conservation Union) Mission: “to influence, encourage and assist societies throughout the world to conserve the integrity and diversity of nature and to ensure that any use of natural resources is equitable and ecologically sustainable.” The IUCN Red List uses a set of criteria to evaluate the extinction risk of species and subspecies. The overall aim of the Red List is to convey the urgency and scale of conservation problems to the public and policy makers, and to motivate the global community to try to reduce species extinctions. www.iucn.org CITES Convention on International Trade in Endangered Species of Wild Fauna and Flora An international agreement, drafted by IUCN (World Conservation Union) which aims at regulating wildlife trade. Perhaps the most effective conservation treaty in existence, with 150 countries participating. CITES Appendix I Commercial trade prohibited. Appendix II Commercial trade permitted under special circumstances. Trade highly regulated. Appendix III Commercial trade permitted but regulated. Species specific to a region. This is what CITES regulates: U.S. Fish and Wildlife Service Endangered Species Act • Provides a means whereby the ecosystems upon which endangered species and threatened species depend may be conserved. Endangered Species = any species which is in danger of extinction throughout all or a significant portion of its range Threatened Species = any species which is likely to become an endangered species within the foreseeable future Washington Department of Fish and Wildlife • Maintains a Species of Concern list (includes endangered, threatened, sensitive and candidates for listing) Washington Natural Heritage Program of the Department of Natural Resources • Produces a list of “Endangered, Threatened, and Sensitive Vascular Plants of Washington with Working Lists of Rare Non-Vascular Species” Woodland Park Zoo’s working definitions: • Endangered = refers to a species that is listed as endangered on the IUCN Red List, as endangered on the USFWS Endangered Species List, or on Appendix I to CITES • Endangered in Washington state = refers to a species that is listed as endangered by the WDFW (animals) or the Washington Natural Heritage Program (plants) Conservation of Biodiversity Conservation: What is being done for endangered species? Association of Zoos & Aquariums (AZA) Programs • AZA, established in 1972, aids North American zoos through the coordination of conservation, education, scientific study and recreation • AZA accredits North American zoos to ensure that they meet certain standards Conservation Action Partnerships (CAPs) • Regional programs developed for the purpose of coordinating conservation efforts in a particular country. Example: Madagascar CAP Taxon Advisory Groups (TAGs) Programs focusing on the conservation needs of entire taxa, or groups of related species. Example: Felid TAG Species Survival Plans (SSPs) Programs that ensure the survival of selected species. SSPs focus on habitat preservation, maintenance of healthy captive populations, scientific research, and public education. In some situations efforts are made to reintroduce species into the wild.
