Wolverine- Endangered. The largest and least known terrestrial member of the Mustelidae family. The wolverine is a cross between a skunk and a black bear Native to California. http://www.allaboutwildlife.com/endangered-species/californias-endangered-animals/6037 http://bss.sfsu.edu/holzman/courses/fall00projects/wolverine.html Trappers hunted wolverines for their fur in North America. In the past, their fur was used to line parkas, but this is less common today and the animals are protected in many areas.

Quagga- (extinct since 1883) Half horse, half zebra. The quagga had been hunted to extinction for meat, hides, and to preserve feed for domesticated stock. The last wild quagga was probably shot in the late 1870s, and the last specimen in captivity died on August 12, 1883 at the Artis Magistra zoo in Amsterdam. Were located in South Africa. http://www.oddee.com/item_88742.aspx http://www.petermaas.nl/extinct/speciesinfo/quagga.htm quagga descended from a population of plains zebras that was isolated some time ago

Lichens- Indicator species. Lichens absorb water and minerals from rainwater and directly from the atmosphere, over their entire surface area. This makes them extremely sensitive to atmospheric pollution. There are usually very few lichens around industrial centers and towns. http://www.countrysideinfo.co.uk/fungi/lichens.htm http://www.fia.fs.fed.us/library/fact-sheets/p3-factsheets/lichen.pdf epiphytic lichens provide a clear indication of potential air quality impacts on total forest productivity. Different lichen species vary in their tolerance to pollution and therefore make very good biological indicators of levels of atmospheric pollution.

Cane Toad. They turned out to be failures at controlling beetles. Fast reproducing and spreading themselves. About 3,000 cane toads were released in the sugarcane plantations of north Queensland in 1935 Their effects on Australia's ecology include the depletion of native species that die eating cane toads; the poisoning of pets and humans; depletion of native fauna preyed on by cane toads; and reduced prey populations for native insectivores, such as skinks. They are considered pests, and the government is asking residents to help collect and dispose of them. http://animals.nationalgeographic.com/animals/amphibians/cane-toad/ http://www.honoluluzoo.org/cane_toad.htm
