Laguna Watershed Knowledgebase

The Santa Rosa Plain is home to both natural and created vernal pools and swales that harbor the endangered annual plants Blennosperma bakeri, Limnanthes vinculans, and Lasthenia burkei. Questions
to be answered to promote the recovery of these species are:
1. What pollinators do plants rely on to reproduce?
2. What is the ecology and distribution of these in- sect pollinators?
During the spring of 2009, we conducted a pilot study to observe insect visitors to floral populations of each species at both naturally occurring and man-made or created pools across the blooming season. We performed timed observations across different flower cohorts and cover class densities.
