2010 spotted knapweed project

Project leader: W. Brinkmann

Clark Lake-North Beach

Eastern section:

mowing spotted knapweed All plants on the sandy strip next to the water and numerous outlyers to the north were hand-pulled. The most densely infected strip along the portion of the Clark Lake trail running across the eastern section of the beach was mowed (on a very hot and hazy day). All plant matter was bagged and removed.

 

Western section:

Loon Lake

There is a patch of spotted knapweed growing on the northern sandy shore, just east of the Clark-Loon portage trail. This patch has been in existence for several years and a number of visitors, realizing the problem, have pulled the plants. Unfortunately, some visitors then throw the plants on the ground which only spreads the seeds.

All plants and a large number of first-year rosettes were hand-pulled. Plant remains found on the ground were gathered. All plant material was bagged and hauled across Clark Lake by kayak.
