With respect to getting to the BMP question, BMPs are voluntary. These are not mandatory measures.
One of the reasons for that—and you've heard from other witnesses—is that not all BMPs can be applied at all times. There are a variety of situations, for instance, where the window to plant seed is very narrow and you're only able to have a day, let's say, to plant your field. You may not be able to implement all of the best management practices.
The idea of this is to have a suite of practices so that farmers can implement as many as practical in order to try to minimize risk to pollinators.
