A 'living fossil' in California
Article Abstract:
The vernal pool tadpole shrimp is a living fossil that derives its name from its appearance. The shrimp's general body characteristics have remained unchanged for millions of years. Vernal pools are occasional wetlands which form in Mediterranean-climate areas and are filled during during winter and spring. The shrimp is found only in vernal pools of the San Francisco Bay area and California's Central Valley. The shrimp's main threat to survival is loss of habitat, mainly due to land conversion. The Habitat Conservation Plan is one way to protect the shrimp.

A second chance
Article Abstract:
Arthur Bonner was hired by Rudi Mattoni to work on a conservation project involving the Palos Verdes blue butterfly at San Pedro, California. Bonner is raising butterfly eggs as well as growing wild plants from cuttings. He sees this work as having taken him from Los Angeles street life, and plans to study for a college degree. He is helped by a number of volunteer groups, including Rhapsody in Green, the Youth Environmental Service program and Clean and Green.
