Roger Batt, with the Idaho Weed Awareness Campaign and Bryan Dallolio, Ada County Weed Control, inspect a patch of Poison Hemlock growing close to the Boise River and against a tall fence. Roger asks if this is a typical location for this plant. Bryan thinks it is and guesses that this infestation was probably started from a man made disturbance on the other side of the fence. The movement of soil and placement of these large rocks left an opening for this invasive weed. Being close enough to the river to gain moisture, the plant has had an ideal situation in which to grow and develop.
Note that there are several video "hot spots" available which provide a lot more detailed information.
