  Beijing Municipality has 20 nature reserves that have a total area of 1,339.7 km (517.3 sq mi). The mountains to the west and north of the city are home to a number of protected wildlife species including leopard, leopard cat, wolf, red fox, wild boar, masked palm civet, raccoon dog, hog badger, Siberian weasel, Amur hedgehog, roe deer, and mandarin rat snake. The Beijing Aquatic Wildlife Rescue and Conservation Center protects the Chinese giant salamander, Amur stickleback and mandarin duck on the Huaijiu and Huaisha Rivers in Huairou District. The Beijing Milu Park south of the city is home to one of the largest herds of Père David's deer, now extinct in the wild. The Beijing barbastelle, a species of vesper bat discovered in caves of Fangshan District in 2001 and identified as a distinct species in 2007, is endemic to Beijing. The mountains of Fangshan are also habitat for the more common Beijing mouse-eared bat, large myotis, greater horseshoe bat and Rickett's big-footed bat.
  
  Each year, Beijing hosts 200–300 species of migratory birds including the common crane, black-headed gull, swan, mallard, common cuckoo and the endangered yellow-breasted bunting. In May 2016, Common cuckoos nesting in the wetlands of Cuihu (Haidian), Hanshiqiao (Shunyi), Yeyahu (Yanqing) were tagged and have been traced to far as India, Kenya and Mozambique. In the fall of 2016, the Beijing Forest Police undertook a month-long campaign to crack down on illegal hunting and trapping of migratory birds for sale in local bird markets. Over 1,000 rescued birds of protected species including streptopelia, Eurasian siskin, crested myna, coal tit and great tit were handed to the Beijing Wildlife Protection and Rescue Center for repatriation to the wild.
  
  The city flowers are the Chinese rose and chrysanthemum. The city trees are the Chinese arborvitae, an evergreen in the cypress family and the pagoda tree, also called the Chinese scholar tree, a deciduous tree of the family Fabaceae. The oldest scholar tree in the city was planted in what is now Beihai Park during the Tang dynasty.
