Most of the areas currently under management have been managed for five years or more leading to an obvious reduction in plant numbers citywide. Keeping track of what’s left still takes a lot of time and effort, and not all areas respond equally. We hire professional crews to help us treat and survey almost 80 miles of roadside, in addition to many private properties. The good news is that our management efforts rely less on crews every year, as the density of garlic mustard decreases. That means city staff alone can do more of the work.
