"Why not?"?? Because chainsaws cause wildfires.  
Good grief.

Jan, you bring up a great point which I did not mention. Chainsaws do have the ability to be an ignition source if the chain hits a rock, or when the exhaust gets hot enough. Utmost care should be taken during dry conditions, or the tool shouldn’t be used. With that being said, chainsaws are an incredible tool managers can use to manipulate vegetation structure and alter fuel loads on the ground. In many of our landscapes reduction of woody fuels, native and non-native, would be a benefit to reduce the intensity and size of fires when they do burn.

Hi Thomas,  
I know the article was on chainsaws, but it does mention cut stump herbicide treatment and urban forestry. Since you bring those subjects up, it might not hurt to mention that urban trees can and do graft roots with other trees (usually only others of the same species). Systemic herbicides are designed to be translocated through roots, and can thereby damage or kill adjacent trees - so look and think carefully before using this technique.

Hi Steven,  
That is an excellent point, and thank you for the comment! There is certainly potential for non-target impact when using a cut stump treatment. As you mentioned injury could occur to adjacent species if root graphing has occurred. It is amazing how well some of these herbicides can move in connected plants. I have observed multiple willow stems (trees) show significant herbicide injury after a single stem, was treated with a hack and squirt treatment as the herbicide moved through the root system. However, root grafting is not the only way non target species might be impacted. Damage could be seen to species surrounding the stump, either through direct contact from the application, or movement if the herbicide volatilizes after application (triclopyr is a compound know for high volatility). Being aware of potential off-target impacts when using herbicides is of utmost importance, especially when working in the urban landscape with high-value vegetation.  
Thanks again for bringing up this excellent point!
