In the coming weeks, the University of Montana will spray for weeds, work on the "M" trail and restore native plants on Mount Sentinel.

Officials say volunteers are needed to do much of the work, but UM staff will do the weed spraying through the first week of November.

The weeds are mainly leafy spurge, dalmation toadflax and spotted knapweed. Much of the weed work will be done above the fire road on the mountainside and the spray will be tinted blue so workers and others know which areas have been treated.

October 12 will be a workday on the M Trail, in cooperation with the Montana Conservation Corps. A new retaining wall will be installed below the north fork of the M and will be backfilled with gravel. Volunteers are needed to help carry gravel from the fire road to the M.

On November 2, UM staff will spread native grass and wildflower seeds. Volunteers can also help, and will meet at the trail at noon. Be prepared for steep, off-trail hiking.
