Issue:

ATV trail that crosses the stream with a metal culvert. The beaver activities is surrounding the area, and as a result the metal culvert (0.9 m) is completely blocked. Accessibility to trail blocked due to the stream running over and eroding trail.

Action Required:

The brook banks should be stabilized (with rip-rap rocks or with vegetation) in order to slow down erosion and reduce sedimentation in the brook. Visitors must be educated on importance of maintaining an adequate buffer zone in the region. A ‘‘Erosion protection’’ and/or ‘‘No dumping’’ sign should be erected near the site. Restore the buffer zone from the beaver activities and by planting shrubs or by letting nature take its course by leaving a strip of untouched vegetation along the shore. A ‘‘beaver activities’‘ sign should be erected near the site.
