Birch Island Park Reserve, located in natural region 5a & b in Lake Winnipegosis was protected in 2000 based on a First Nation community nomination. The interim regulation to protect the island, surrounding waters, plus several small islands, reefs, and shoals for nesting birds, was among the first set of protected areas announcements made by Manitoba's NDP government.

In September 2010 Conservation Minister Blaikie said, "We want to protect the Birch Island area for future generations to enjoy as great example of Manitoba’s varied landscapes." Public comments were requested and regulations signed in November 2010.

The Birch Island park reserve connects to Chitek Lake Park Reserve, which was also First Nation nominated, though only one third of the lands nominated and approved for protection by Manitoba's mining sector, was protected.
