(22-23高二下·江苏无锡·期中)Deciduous forests (落叶林) are home to many wild animals. The development and expansion of human presence in the forests has caused many of their native species to become endangered.
Giant Panda
The giant panda, one of the most recognizable endangered species, is a large, docile species of bear native to the deciduous forest of eastern China Myanmar and Vietnam because of its limited diet--the panda’s main source of food is bamboo--the species is limited in its habitat to areas where bamboo is available. Now the species only can be found today in 20small patches of forest at the western edge of its historic range.
Gray and red wolves
The gray wolf, which once ranged from the East Coast of America to the west, and south to Mexico, now has a population of only 5,000 in the lower 48 states, mostly in the Rocky Mountains. The smaller red wolf, native to the southeastern United States, was declared extinct in the wild in 1980, though conservation efforts have reintroduced small captive populations to the wild in California.
Red-Crowned crane
The red -crowned crane is native to Japan, Korea and eastern China. Agricultural expansion and deforestation in these areas have removed a great deal of the marshes and forests that are the crane’s primary habitats. For a time, the crane was thought to have completely disappeared from Japan, but the recent discovery of cranes in Japanese marshlands has restarted conservation efforts. Today, around 2,500 cranes live in the wild, including 1,000 in Japan.
European Mink
Native to Europe, the European mink ranges from France in the west to Finland in the north, Russia in the cast and the Balkans in the south. Destruction of the mink habitat and use of the species for fur have caused dramatic drops in the species’ population, which has been reduced by 85 percent since the mid-19th century.
