Gladys Lake Ecological Reserve

Gladys Lake Ecological Reserve is an ecological reserve located in the Eaglenest Range of the Spatsizi Plateau in north-central British Columbia, Canada. It was established in 1975 under the Ecological Reserves Act to facilitate scientific research of the region's alpine-subalpine ecosystems while discouraging outdoor recreation use. The reserve protects 44098 ha of pristine wilderness and is the largest ecological reserve in British Columbia.

Geography
The reserve is an enclave within the larger Spatsizi Plateau Wilderness Provincial Park, though with stricter protections and limited public access.
