This book was released on 2012 with total page 27 pages. Available in PDF, EPUB and Kindle. Book excerpt: Coastal sage scrub (CSS) is an important vegetation type in Southern California, which is under threat from multiple environmental changes such as nitrogen deposition, invasion by exotic species, and accelerating fire regimes. While previous studies have found that CSS can recover pre-fire cover through a successional process, there is concern that high exotic annual grass abundance after fire could prevent native shrub recovery, creating an alternate stable state which requires an active management for restoration of native shrub cover. This study evaluated the performance of focal native and exotic species at early demographic stages (germination, first-year growth and survival) in one recently burned site, and then placed these short-term results in context by examining long-term vegetation dynamics across four CSS sites in San Diego County. Exotic species out-performed native species during all early demographic stages, especially following fire. In the long-term (20 years) cover by native CSS shrubs returned to pre-fire levels at three of the four sites monitored. These results indicate that invasion slows the rate of CSS successional recovery post-fire, and that native CSS vegetation can recover given a long-enough fire return interval. Accelerating fire frequencies, however, may be creating invaded "apparent stable states," because full native shrub recovery does not effectively occur between closely spaced fires.

This book was released on 2006 with total page 87 pages. Available in PDF, EPUB and Kindle. Book excerpt: The distribution of coastal sage scrub (CSS) vegetation in Southern California is strongly influenced by local disturbance regimes. Focusing on CSS stand boundary shifts over time in the Cheseboro and Palo Comado Canyons of the Santa Monica Mountains, this study assesses the influences of wildfire frequency on changes observed in multiple historical aerial photograph sets. Fire perimeter data and field sampling data were also utilized to evaluate vegetation cover change over two distinct time periods: 1929-1976 and 1976-2003. Fire perimeter data and burn frequencies were correlated with CSS coverage change calculations at a coarser scale, and field sampling data was analyzed to determine the influences of fire frequency on CSS stand dynamics at a finer scale. While dramatic CSS coverage loss was observed in portions of the study area with documented high fire frequencies, correlations between CSS/grassland ecotone fluctuations and fire frequency were inconclusive.

This book was released on 2012 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: California sage scrub (CSS) and adjacent vegetation communities have experienced significant declines due to numerous anthropogenic disturbances. A number of areas have been set aside on the Palos Verdes Peninsula to preserve open spaces and protect at-risk species. An analysis of the vegetation dynamics in the Portuguese Bend area of the Peninsula was performed using historical aerial imagery and derived land-cover classifications. Image data was classified using an object-based segmentation method combined with a ground-based classification. The land-cover layers were derived for six separate time periods, covering fifty years, and the layers were compared to determine what types of changes had occurred within the study area. The changes observed in this study are discussed using four hypothesized models as recovery determinants. While challenges were encountered due the chaotic nature of disturbance in the area, the aerial photos and land-cover layers provide an invaluable record of change within the Portuguese Bend Reserve.

Available in PDF, EPUB and Kindle. Book excerpt: Significant resources are invested in the restoration of degraded Coastal Sage Scrub in Southern California to meet conservation goals. Thus, understanding the resilience of these systems is of great importance given their high value intersection with human settlements. The presence of invasive annual species has been suggested to add complexity to ecological restoration efforts by inhibiting the growth of native species, changing fire regimes, and altering water balance. To further understand these ideas, I utilized a long-term experiment testing the effectiveness of "passive" restoration, the removal of non-native species without expensive site preparation or resource-intensive active planting / seeding of native species, which means that the approach could be designed to have widespread positive effects at potentially minimal costs. I found that passive restoration was successful at meeting restoration goals of increasing native shrub cover. Two ecological mechanisms---the establishment of new individuals on the landscape versus the expansion of plant size of existing shrubs---were likely responsible for the variation in patterns of recovery for localities with different initial native shrub cover. These patterns give insight into how to affect change in communities through management intervention. Better formulating a conceptual model of the contemporary dynamics of Coastal Sage Scrub informs decisions on expending limited resources to different intensities of restoration across a complex landscape to maximally impact conservation.
