We also collected some Italian Thistles that were in the vicinity. When we thought we had […]
In our third week of Star-thistle Wars, the BFS volunteers focused on an infestation around the ‘new’ toad pond and the areas along the trails and fire roads just southeast of pHake Lake. We removed nearly all the star-thistles in this area, and the haul made quite a mound!
