Work is underway in Riding Mountain National Park to remove trees planted on native grassland some 50 years ago.
Park officials say the work in the Clear Lake area is to help protect homes, cottages and businesses from wildfire.
The work is being carried out over a 25-hectare area and is expected to continue until mid-February 2017.
Park staff have been removing old tree plantations since 1990 to help mitigate wildfire risk to Wasagaming and restore native grasslands. The white spruce plantations were originally planted on native grasslands between 1940 and 1960
Parks Canada staff, Indigenous and private contractors are working together on the project over the next few months.
Visitors are asked to use caution if travelling in this area and watch for heavy equipment and crews working adjacent to Highway 10 and in the Wasagaming townsite.
