Technical Abstract: That human activities can decimate or impoverish local and regional biotas is indisputable, but what about claims for such losses among North America's native bees, whose loss is most likely to have far-reaching effects for pollination? In this journal issue, we conclude that we do not presently know the net effect of these confounding factors on native North American invertebrate pollinator faunas. An answer will require a more concerted and rigorous effort that will employ multiyear replicate stratified sampling to accommodate daunting spatiotemporal variability in bee communities, thoughtful consideration of sampling biases, care in taxonomy, and a reconsideration of the attributes of "habitat" from the bee's perspective.
