Invasive: European Starling (Sturnus vulgaris Linnaeus)• Native to Europe, introduced to the
United States in 1890 in an effort to bring all birds mentioned in Shakespeare’s works to the U.S.
• Identifying characteristics include an iridescent gloss on black feathers and cream-colored tips on feathers. • Because they are generalists, the starlings were able to thrive wherever they were introduced. They can eat a variety of organisms and have are able to drive out any competition.• Courses of action for removal include habitat modification to remove possible nesting sites, poisoning, shooting, and trapping.
Keystone: Coyote (Canis latrans)• Opportunists who are able to
survive in a variety of habitats in the United States including grasslands, deserts, mountainous areas, farmlands, and metropolitan areas.
• Resembles a German shepherd dog, have long, bushy tails that drag to the ground, and long, narrow muzzles.
• The coyote regulates small predator populations by preying on them. As a result, the prey of these small predators are able to survive, thus maintaining a balance in the food web.
• Coyote populations are threatened by humans who fear their proximity to developments. Most are killed by humans after attacking a human. Coyote attacks can be prevented by not feeding the coyote and building fences that coyotes cannot jump or climb.
Indicator: Spotted Owl (Strix occidentalis)• Live primarily in old-growth
forests in the Pacific Northwest, including California.
• Large, have a round head with no ear tufts, and dark eyes.
• These species indicate the existence of an old-growth forest. As old-growth forests are removed due to human development and timber harvesting, the spotted owl population has declined.
• The identification of old-growth forests should be employed by timber and developing companies. Laws to protect these forests should be enacted to prevent their removal.
Extinct: Tecopa Pupfish (Cyprinodon nevadensis calidae)
• Native and exclusive to hot springs of Mojave Desert. Declared extinct in 2010.
• Dorsal fin is closer to the tail than the head, and can either have very small for no fins at all.
• Extinct after natural habitat was destroyed by developers.
Endangered: Large-flowered Fiddleneck (Amsinckia grandiflora)
• Plant that is native to California. It produces very few seeds and has a low tolerance to environmental changes. Only three populations still exist.
• Has bright orange flowers.• Reasons for status include
agriculture, invasive species, human development, and grazing.
• Reserve established to protect species.
Threatened: Eastern Prairie Fringed Orchid (Platanthera leucophaea)
• Grows in open prairies in Ohio, Illinois, Iowa, Wisconsin, Maine, Michigan, and Virginia.
• Leafy stem with a creamy white three-fringed flower cluster.
• Status due to land cleared for agriculture.
• Courses of action for protection include habitat protection and careful monitoring of populations.
