context_page_description: Prisurski Nature Reserve is a Russian zapovednik in the northern Volga Uplands of the East European Plain. It protects for study an area of forest-steppe and mixed forest, with sections in different parts of Chuvashia. The largest sector is the Alatyrski Nature Reserve, located in the valley of the Sura River, and two small steppe sections to the southeast. The reserve is situated in the Alatyr, Chuvash Republic District of the Chuvash Republic. It was set aside as a reserve in 1995 to protect the largest and least disturbed area of southern taiga lowland forest in Chuvashia, as well as steppe habitat at the northern edge of its range. A particular concern was protecting habitat of the muskrat and seasonal waterfowl. The reserve covers an area of 9,150 ha.
context_section_description: In the Alatyrski site, the floral communities are northern deciduous forests (66% of the ground), with smaller conifer forests of Scots pine and spruce (33% of the territory).  The age structure of the trees (as of 2013) was 24% young, 53% middle-aged, 10% maturing, and 13% mature and beyond.  Scientists on the reserve have recorded 722 species of flowering plants.
  The animal life of the reserve is representative of mixed deciduous forests and meadow steppes.  The reserve is known in particular for the population of Bobak marmots on the Batyrevski tract.  Scientists on the reserve have recorded 44 species of mammals, and 175 species of birds.
