The Nuratau-Kyzylkum Biosphere Reserve (NKBR) was established "to conserve the globally important biodiversity, landscapes and cultural assets of the Nuratau Mountain Range and the adjacent Kyzylkum Desert". The Reserve is said to be the only place in the world where the endangered Severtsov wild sheep (Ovis ammon severtzovi) still roam in the wild. It has also an endemic collection of unique flora and a diverse spread of nut and fruit trees, including strands of pistachio and rare walnut. References
