UC Riverside botanist to study role of plants in southern California's drought
Date:9/11/2008

a>, an assistant professor of biology at California State University Bakersfield, noted that Santiago's work on drought tolerance could not have come at a more important time.

"Southern California has been gripped by severe droughts in the last decade," he said. "Dr. Santiago's study will help shed light on which species are most in peril of succumbing to drought-induced death."

Pratt explained that Southern California is a global plant biodiversity hotspot that in some ways is more threatened than the rain forests.

"One of the chief threats is climate change, and Dr. Santiago's work will help to deepen our understanding of this threat and will contribute to understanding of how to mitigate its negative impacts," he said.

Richard Minnich, a professor of geography at UCR and fire ecology expert, noted that Southern California has been in a water deficit for urban and agricultural use ever since the Owens River aqueduct was completed in the early 20th century.

"It is vital to understand relationships between plants and water in chaparral and desert watersheds that deliver valuable small additions to the region's water supply," Minnich said. "This study will evaluate important questions on the effect of drought on plant species, especially in view of the recent great drought and die off or dieback of forest trees and shrubs of the chaparral. The findings will also help in the assessment of watershed transpiration in the region's fire regimes."

Santiago's project will create opportunities for UCR students to do research on local ecosystems.

"Our students, like most Southern Californians, are familiar with water-related services such as freshwater supply, flood protection and recreation," Santiago said. "I expect this project will excite many of our students, preparing them to become leaders of natural resource management."
