This pool was completely dry a few months ago and now is teeming with life. There are northern harrier hawks and killdeer flying nearby. As a vernal pool dries up, the creatures activate their dormant strategies. If there is lots of water and it warms up there are numerous generations. If there is less water and cooler, only one generation hatches.
Alpha diversity means the diversity within one pool.
Beta diversity relates to two pools relative to each other. Plants around the pools include Brodea hyacyathia, Triteleia hyacinthina , delphiniums, and Medusahead grass. The last pool really brought home the diversity of life that springs up out of a seemingly dry spot in the ground. Before this trip I had no idea of this unique California asset.
