Uzbekistan operates 10 state nature reserves, nine national parks, and three biosphere reserves recognized by UNESCO, protecting approximately 4.8 percent of the country's 448,978 square kilometers. The network expanded significantly after independence in 1991, when Soviet-era designations were reorganized under the State Committee for Ecology and Environmental Protection, later restructured into the Ministry of Ecology, Environmental Protection and Climate Change in 2019. These protected areas span five distinct ecological zones: the Western Tian Shan mountains in the northeast, the Pamir-Alai foothills in the southeast, the Kyzylkum Desert covering central regions, tugai riparian forests along the Amu Darya and Syr Darya rivers, and the Ustyurt Plateau in the west.
Ugam-Chatkal National Park encompasses 574,600 hectares across the Tashkent and Namangan regions in the Western Tian Shan range. Established in 1990 through the merger of the Chatkal Biosphere Reserve (created 1947) and Ugam Ridge territories, the park protects elevation gradients from 1,100 meters to 4,299 meters at Bashkyzylsay Peak. The UNESCO World Heritage designation "Western Tien Shan" inscribed in 2016 includes portions of this park alongside sites in Kazakhstan and Kyrgyzstan. Juniper forests of Juniperus seravschanica cover mid-elevation slopes between 1,800 and 2,800 meters. Wild walnut groves of Juglans regia concentrate in Okhangaron and Pskem valleys. The park harbors 43 mammal species including Menzbier's marmot, endemic to this mountain range with a global population under 5,000 individuals. Snow leopards pass through at densities estimated at one individual per 100 square kilometers based on camera trap data from 2018-2020. The Chatkal River system contains the endangered Aral trout, though populations declined 90 percent since 1960 due to upstream damming. Access requires permits from the park administration in Tashkent, issued within three working days. The Chimgan and Beldersay ski areas operate on the park's western boundary with separate commercial concessions.
Zaamin National Park covers 24,130 hectares in the Jizzakh Region at elevations between 1,760 and 4,060 meters on the northern slopes of the Turkestan Range. Declared in 1926 as Zaamin Nature Reserve, it received national park status in 1976, making it Uzbekistan's oldest continuously protected area. Juniper forests here reach ages exceeding 600 years according to dendrochronological sampling conducted by the Institute of Botany in 2015. The dominant species Juniperus seravschanica grows at 0.8 millimeters diameter per year, with some specimens measuring 12 meters in circumference. Apple, almond, and barberry species create understory diversity. The park recorded 47 mammal species, 160 bird species including golden eagles and bearded vultures, and 700 plant species, 30 of which are endemic to the western Pamir-Alai system. Suffa Observatory, operated by the Ulugh Beg Astronomical Institute, functions at 2,600 meters elevation within park boundaries under a 1983 agreement allowing scientific infrastructure. The Sharifbay and Guralash canyons provide hiking routes of 8 and 12 kilometers respectively. Park headquarters in Zaamin town issues entry permits valid for single or multiple days, with fees set at 20,000 som for foreign visitors as of 2024.
The Nuratau-Kyzylkum Biosphere Reserve spans 537,300 hectares across the Navoi and Jizzakh regions, designated by UNESCO in 2010. It comprises three core zones: the Nuratau Range mountains covering 22,000 hectares, the Kyzylkum Desert transitional zone of 140,000 hectares, and Aydar-Arnasay Lakes System of 375,300 hectares. The Nuratau Mountains rise abruptly from the desert floor to 2,169 meters at Hayatbashi Peak, creating a sky island effect with relict populations isolated since the last glacial maximum 20,000 years ago. Wild rams of the severtzovi subspecies, numbering approximately 3,500 individuals based on 2020 counts, inhabit rocky slopes above 1,400 meters. The Sevinch petroglyphs near Sentob document Bronze Age presence dating to 1500 BCE. Six rural communities—Asraf, Hayat, Sentob, Uhum, Yangikent, and Farish—participate in the buffer zone under community-based natural resource management protocols established in 2007 with technical assistance from the German development agency GIZ. Residents operate 14 guesthouses providing overnight accommodation and serve as guides for hiking routes to Farkhad waterfall and Fazilman cave. Aydar Lake, formed accidentally in 1969 when flood waters from the Syr Darya overtopped irrigation canals, now covers 3,000 square kilometers and supports commercial fishing yielding 500 tons annually, primarily carp and pike-perch. Yurt camps operate along the lake's southern shore from April through October.
Surkhan State Nature Reserve protects 24,551 hectares of the Hissar Range foothills in the Surkhan Darya Region near the Tajikistan border. Established in 1986, the reserve's lowest point at 300 meters elevation along the Sangardak River represents the warmest area in Uzbekistan, recording 47 degrees Celsius in July 2019. Pistachio woodlands of Pistacia vera cover 8,000 hectares, with trees yielding nuts commercially harvested in buffer zones under permit. The Kobadian Plain transitional zone hosts striped hyenas, the only population confirmed in Central Asia through camera trap evidence published in 2017. Central Asian cobra populations persist in rocky gullies below 1,000 meters. Archaeological surveys documented 120 Buddhist and pre-Islamic sites including Fayaz-Tepe monastery active from the 1st century BCE to the 3rd century CE. The reserve prohibits public entry to core zones, permitting only researchers with approval from the Uzbek Academy of Sciences. The adjacent Zarautsoy Gorge outside reserve boundaries allows hiking access.
Badai-Tugai State Nature Reserve encompasses 6,467 hectares of tugai riparian forest along the Amu Darya River in the Republic of Karakalpakstan, created in 1971. Tugai ecosystems, formed by periodic flooding that deposits nutrients while maintaining water tables near the surface, once covered 600,000 hectares in the Amu Darya delta. Diversion for cotton irrigation reduced this to approximately 30,000 hectares by 1990, making Badai-Tugai one of the largest remaining fragments. The dominant tree Populus pruinosa grows in dense stands mixed with willow, oleaster, and tamarisk species. Bukhara deer, extinct in Uzbekistan by 1920, were reintroduced from Tajikistan in 1976; the population numbered 287 individuals in a 2021 census. The reserve provides critical winter habitat for 150,000 waterfowl migrating along the Central Asian flyway, with peak concentrations occurring in November. White-headed ducks, globally threatened with fewer than 10,000 individuals, overwinter in oxbow lakes. Reed beds shelter jungle cats and wild boars. Access requires advance permission from reserve administration in Turtkul, granted primarily for research purposes. The Amu Darya flow averaged 24.8 cubic kilometers per year between 2010 and 2020, compared to 50 cubic kilometers in the 1960s, affecting flooding patterns essential to tugai regeneration.
