Middle Zambezi Biosphere Reserve Middle Zambezi Biosphere Reserve The Middle Zambezi Biosphere Reserve (established 2010) is a UNESCO Biosphere Reserve located along the Zambezi River in the Zambezi Valley of Zimbabwe.. The reserve consists of riverine and terrestrial ecosystems unique to the subcontinent. Among threatened species found in the valley are the black rhino ("Diceros bicornis"), the painted wild dog ("Lycaon pictus"), and the nyala ("Tragelaphus angasii").
