White Lake Grasslands Protected Area is a conservation site located in the Regional District of Okanagan-Similkameen of British Columbia, Canada.

It was established on April 18, 2001[2] by an order-in-council under the Environment and Land Use Act to protect the semi-arid grassland and pine forest ecosystem west of Vaseux Lake.

[3] The region spans from the lake's shoreline to its mountain tops, providing protection and essential ecosystems for various red and blue-listed endangered species native to British Columbia.

[3][4] The overall aim of the land's classification is to protect the ecosystems and rare or endangered species located in the Southern Okanagan Basin.

[5] The White Lake Grasslands Protected Area drew significant interest from settlers during the 1850s gold rush, leading to the displacement of the Syilx/Okanagan people and the loss of their essential resources and territory.

[5] During the period, intense cattle grazing caused damage to the grasslands, resulting in the replacement of native grasses with low-growing, graze-resistant shrubs, leafy forbs, and invasive plants.

The area is located within the South Okanagan Basin Ecosection, which features a hot, xeric climate originating from the Ponderosa Pine biogeoclimatic zone (PPxhl).

[5] This region has an overflowing amount of species at risk that inhabit mid-elevation grasslands and old-growth ponderosa pines.

[4] Areas that need to be protected are identified with the guidance of the Okanagan-Shuswap Land and Resource Management Plan (OSLRMP).

[4] The Okanagan Valley is one of Canada's most threatened ecosystems,[3] making the White Lake Grasslands Protected Area crucial[5] for the survival of species such as the White-headed woodpecker.
