The Canadian Forces Base (CFB) Shilo is located in the mixed-grass prairie ecosystem of south-central Manitoba and is controlled by Canada’s Department of National Defence. While it is managed primarily for defence, CFB Shilo has specific secondary objectives focused on the conservation of biodiversity.

While portions of CFB Shilo have infrastructure and high human traffic, there are areas on the base that are largely natural habitats and which support diverse plant and wildlife communities. These natural areas were collaboratively assessed by the federal Department of National Defence and the provincial (sub-national) Government of Manitoba. They were found to meet all necessary conditions to be reported as an Other Effective Conservation Measure (OECM) and were reported by the Government of Manitoba for inclusion in the Canadian protected and conserved areas database.

CFB Shilo is the first Canadian military base recognized as a part of the Canadian protected and conserved areas network.
