The goal of the park is to work with the local First Nations to protect a large patch of Okanagan dry forests and part of the northern reach of the Columbia Plateau ecoregion in Canada.

[6] In 2010, the proposed park was revised down to 28,400 hectares (70,000 acres) with a greater emphasis placed on protecting lower elevation grasslands where species diversity is highest and most at risk.

As of this memorandum, the park reserve encompasses an area of 27,300 hectares (67,000 acres) stretching from the southern slopes of Orofino Mountain to the Canada–United States border.

In addition, the park reserve would absorb the existing protected areas of South Okanagan Grasslands and Field's Lease.

[1] With the onset of the COVID-19 pandemic in Canada in early 2020, progress in reaching an establishment agreement between senior governments and local First Nations slowed significantly.
