California Central Valley Pollinators
(in progress)Introduction
California’s Central Valley is not a hotspot for bee or butterfly biodiversity compared to the southwestern deserts or even the Coast Ranges. In fact, many bees and butterflies seem to have a distribution in the hills and mountains while avoiding the valley. This list for ecological and agricultural purposes. Many bees seem to hug the riparian zones in the valley and little attention has been paid to them. Robbin Thorp (UCDavis) and Joan Leong have studied vernal pool bees, but a metapopulation analysis of their dynamics is a distant prospect.
The legendary work of Andy Moldenke included efforts to sample pollinators from every plant in sight. More recently Claire Kremen (Princeton), Bob Bugg (UCDavis), Robbin Thorp and coworkers are trying to assess the ecosystem service value of native pollinators in the Capay and Central Valleys.
The phenology and distribution of butterflies has been the 30 year work of Art Shapiro (UCDavis). Many moths have been studied by Jerry Powell (UCBerkeley).
The checklist of pollinators, gleaned mostly from the systematics literature is sure to grow, and I hope to add ecological detail later.
