Coastal Sage Scrub Succession1
Professor of Geography, University of California, Los Angeles, California 90024 USA Abstract: Unlike chaparral, shrubs of coastal sage are capable of continual seedling reproduction. As a result, mixed-aged stands form which show little senescence. Litter turnover is twice as rapid. The more open sage scrub canopy permits persistence of a diverse herb layer into mature communities. Crown sprout...
متن کاملFire as a Threat to Biodiversity in Fire-Type Shrublands
Chaparral and coastal sage scrub communities have a disproportionately high number of rare and endangered plants and thus are of particular conservation concern. Unnaturally high fire frequency has been a leading cause of degradation of chaparral and coastal sage scrub ecosystems. Although these shrublands are fire-adapted, below a certain threshold of fire frequency, resilience is inversely re...
متن کاملComparative Nutrient Relations in Adjacent Stands of Chaparral and Coastal Sage Scrub1
Research Associate, Department of Biological Sciences, University of California, Santa Barbara, California, 93109. Abstract: Productivity and nutrient cycling parameters were measured in mature stands of chaparral and coastal sage scrub in the Santa Monica Mountains, California, USA. Net annual production and the magnitude of annual nutrient transfers were much greater in the evergreen chaparra...
متن کاملComparison of post-®re seedling establishment between scrub communities in mediterranean and non- mediterranean climate ecosystems
1 Both ®re regimes and the conditions under which ®res occur vary widely. Abiotic conditions (such as climate) in combination with ®re season, frequency and intensity could in ̄uence vegetation responses to ®re. A variety of adaptations facilitate post-®re recruitment in mediterranean climate ecosystems, but responses of other communities are less well known. We evaluated the importance of clima...
متن کاملFog and live fuel moisture in coastal California shrublands
9 Across most Mediterranean-type climate regions, seasonal drought desiccates plants, facilitating ignition 10 and the spread of wildfires. Along the California coast, summertime fog has the potential to ameliorate 11 drought conditions and thus reduce plant flammability during a critical time of elevated fire risk. This 12 study investigated the uptake of dry season fog and how it affects live...
