Endangered Species: TIGERS
Bulletin Board Resources for CFs by the Office of Sustainability
Simply cut and paste! Tips for a More Sustainable Bulletin Board:
• Use newspaper for a background instead of butcher paper OR use the backside of the butcher paper from your last bulletin board • Print on used paper that is still good on one side • Recycle all scrap paper when you are done!

Species to Watch: TIGERS QUICK FACTS
!"#$%&'&$((((((((((((((((((((((((((((((((((((((((((((((((((((((((((((((((((($
A species is not classified as extinct until several years after it has last been spotted. Several “endangered” species could therefore actually be extinct already.
!"#$%&'&$(((((((((((((((((((((((((((((((((((((((((((((((((((((((((((((((((((! ! Since 1600, more than 700 species of plants and animals have gone extinct. This is only counting the plants and animals that we know EXIST.
!"#$%&'&$(((((((((((((((((((((((((((((((((((((((((((((((((((((((((((((((((((!
There are about 400 animals in the United States who are listed as endangered, and about 160 that are threatened.
!"#$%&'&$((((((((((((((((((((((((((((((((((((((((((((((((((((((((((((((((((($
Worldwide, there are about 500 animals listed as endangered and 440 listed as threatened.
!"#$%&'&$((((((((((((((((((((((((((((((((((((((((((((((((((((((((((((((((((($
Scientist have named and classified 1.7 million species. It is estimated that 10 to 100 million species actually exist. $
!"#$%&'&$((((((((((((((((((((((((((((((((((((((((((((((((((((((((((((((((((($
30 different species can disappear if just one plant species goes extinct.
!"#$%&'&$((((((((((((((((((((((((((((((((((((((((((((((((((((((((((((((((((($
The current rate of extinction is 100 to 1,000 times higher than the expected natural rate.
!"#$%&'&$((((((((((((((((((((((((((((((((((((((((((((((((((((((((((((((((((($
The number one cause of extinction is habitat loss. Other causes include overexploitation, the introduction of an exotic species, and pollution.
!"#$%&'&$((((((((((((((((((((((((((((((((((((((((((((((((((((((((((((((((((($
In the last hundred years, tiger numbers have declined by 95 percent. There are possibly as few as 3,200 tigers left in the wild.
!"#$%&'&$((((((((((((((((((((((((((((((((((((((((((((((((((((((((((((((((((($
The Bali, Javan, and Caspian tigers have already gone extinct.

!"#$%&'&$((((((((((((((((((((((((((((((((((((((((((((((((((((((((((((((((((($ Amur (Siberian) Tiger Scientific name: Panthera tigris altaica IUCN Listing: Endangered Habitat: Coniferous, scrub oak and birch woodlands Location: Primarily eastern Russia, with a few found in northeastern China Interesting Fact: In the 1940s the Amur tiger was on the brink of extinction, with no more than 40 tigers remaining in the wild. Thanks to vigorous anti-poaching and other conservation efforts by the Russians with support from many partners, including WWF, the Amur tiger population recovered and has remained stable throughout the last decade.

Bengal (Indian) Tiger Scientific name: Panthera tigris tigris IUCN Listing: Endangered Habitat: Dry and wet deciduous forests, grassland and temperate forests, mangrove forests Location: Bangladesh, Bhutan, China, India, Myanmar and Nepal. India is home to the largest population. Interesting Fact: Some Bengal tigers are cream or white in color instead of orange, due to a recessive gene for this coloration. These "white" tigers are rarely found in the wild.

Indochinese Tiger Scientific name: Panthera tigris corbetti IUCN Listing: Endangered Habitat: Remote forests in hilly to mountainous terrain, much of which lies along the borders between countries Location: Widely dispersed throughout six countries: Thailand, Cambodia, China, Lao PDR, Myanmar, and Vietnam. Interesting Fact: Access to the areas where Indochinese tigers live is often restricted, and biologists have only recently been granted limited permits for field surveys. As a result, relatively little is known about the status of these tigers in the wild.

Malayan Tiger Scientific name: Panthera tigris jacksoni IUCN Listing: Endangered Habitat: Tropical and subtropical moist broadleaf forests Location: Southern tip of Thailand and Peninsular Malaysia Interesting Fact: The Malayan tiger was only identified as being a separate subspecies from the Indochinese tiger in 2004. It is very similar to the Indochinese tiger, but is smaller in size.

South China Tiger Scientific name: Panthera tigris amoyensis IUCN Listing: Critically Endangered Habitat: Montane sub-tropical evergreen forest Location: Central and eastern China Interesting Fact: It is estimated that the South China tiger is functionally extinct. Currently 47 South China tigers live in 18 zoos, all in China. If there are any South China tigers in the wild, these few individuals would be found in southeast China, close to provincial borders.

Sumatran Tiger Scientific name: Panthera tigris sumatrae IUCN Listing: Critically Endangered Habitat: Montane forests, the remaining blocks of the island's lowland forest, peat swamps, and freshwater swamp forests Location: Exclusively on the Indonesian island of Sumatra Interesting Fact: Sumatran tigers are protected by law in Indonesia, with tough provisions for jail time and steep fines. Despite increased efforts in tiger conservation, including law enforcement and anti-poaching capacity, a substantial market remains in Sumatra for tiger parts and products.

WORLD WILDLIFE FUND The World Wildlife Fund (WWF) is a global conservation organization that has set the goal of doubling the number of tigers in the wild by 2022, the next year that the Year of the Tiger will be celebrated. The WWF’s primary goal is to protect tiger habitat, as the loss of which is one of the primary reasons tigers are at the risk of extinction.
