The Mid Klamath Watershed Council has surveyed and hand pulled invasive plants in the Siskiyou Wilderness since 2010.  In 2013 we completed inventory of over 90% of the trails, trailheads and priority areas in the wilderness.  In 2014, we will be hand-pulling invasive plants mapped and managed over the last few years.  This work has been supported by both the National Forest Foundation and the Six Rivers National Forest.

Invasive plants found in the Siskiyou are few in number.  Notable occurences include meadow knapweed in the Young's Valley area, Dyer's woad at Poker Flat trailhead and Canada thistle near the Smith River at the Gunbarrel Slide.  Otherwise invasive plants include bull thistle and St. John's wort concentrated mostly near trailheads and other access points.  Please see map for details.
