The Redberry Lake Biosphere Region was established in 2000 as a UNESCO Biosphere Reserve covering 112,200 hectares (277,000 acres) in the province of Saskatchewan, Canada. In 2019, the reserve expanded to become a Region including the Redberry Lake Watershed and surrounding land encompassing close to 700,000 ha (1,700,000 acres) hectares of land. The regional landscape is composed of rolling prairie dotted with seasonal ponds and marshes along with aspen/shrub groves. The core area is Redberry Lake, a saline lake with several islands. There are small patches of natural mixed prairie which are very rare in this highly grazed and cultivated part of the prairies. The Redberry Lake Biosphere Region is committed to balancing conservation with sustainable development.
