Book excerpt: This book is open access under a CC BY-NC 2.5 license. This book provides an unprecedented synthesis of the current status of scientific and management knowledge regarding global rangelands and the major challenges that confront them. It has been organized around three major themes. The first summarizes the conceptual advances that have occurred in the rangeland profession. The second addresses the implications of these conceptual advances to management and policy. The third assesses several major challenges confronting global rangelands in the 21st century. This book will compliment applied range management textbooks by describing the conceptual foundation on which the rangeland profession is based. It has been written to be accessible to a broad audience, including ecosystem managers, educators, students and policy makers. The content is founded on the collective experience, knowledge and commitment of 80 authors who have worked in rangelands throughout the world. Their collective contributions indicate that a more comprehensive framework is necessary to address the complex challenges confronting global rangelands. Rangelands represent adaptive social-ecological systems, in which societal values, organizations and capacities are of equal importance to, and interact with, those of ecological processes. A more comprehensive framework for rangeland systems may enable management agencies, and educational, research and policy making organizations to more effectively assess complex problems and develop appropriate solutions.

This book was released on 2020 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: California's valley grasslands are one of the most invaded ecosystems in the state. It is estimated that valley grasslands contain between 90 to 99% cover of non-native plants. The most recent wave of invasive plants has included medusahead (Elymus caput-medusae L.). Medusahead is an annual grass that matures two to four weeks later than most other grasses. Management of medusahead includes the use of herbicides, targeted grazing, prescribed burns, and mechanical control. The primary focus of most studies on the use of these management methods is on the control of medusahead rather than the impacts on non-target plants. This study examines published research to determine what impact medusahead management has on the composition of plant communities within valley grasslands. Herbicides have mixed impacts on the percent cover of grasses and forbs. Targeted grazing resulted in decreased percent cover of non-native grasses and increased forb cover. Grazing results in neutral to increased percent cover of native plants. Prescribed burns decreased the percent cover of non-native grasses, increased forb cover, and had mixed impacts on native plant cover. Mechanical control shifted vegetative states towards forb or filaree (Erodium spp.) dominated communities. The non-target impacts of medusahead control were generally short-lived with differences in percent cover returning to baseline conditions within one to three years. To mitigate the non-target impacts of medusahead, revegetation efforts should be prioritized in sites with higher abundances of native plant species. The future success of controlling medusahead is dependent upon grassland restoration research, consistent funding for weed management areas to aid in managing invasive plants, and the implementation of monitoring after medusahead control treatments.

Available in PDF, EPUB and Kindle. Book excerpt: Understanding the potential mechanisms that influence invasion resistance and coexistence in plant communities has been a central tenet of invasion ecological research during the past few decades. My dissertation used observational and experimental approaches to understand what processes influence whether a community is invaded, resists invasion, or results in species coexistence within a California grassland. Chapter 2 reviewed the impacts that alien plant species may have on communities and provided a framework for how to identify when invader impacts lead to recovery constraints for the native community and integrate these constraints into restoration efforts. Chapter 3 investigated how species effects on resource availability can result in differing invasion dynamics in native versus exotic dominated grasslands. I found that while exotic and native species differentially alter the availability of light and nitrogen in a community, nitrogen availability is key in determining invasion of an exotic into a native grassland as well as the invasion of a native into an exotic dominated community. Chapter 4 investigated how propagule pressure after an extreme disturbance can result in the invasion of intact native grasslands. I found that the recovery of native grassland stands after an extreme disturbance (fire+drought) can be stalled by an influx of exotic propagules from the surrounding matrix. Chapter 5 addressed how the strength of plant-soil feedbacks for a native and exotic may change with soil resource availability changes on soil communities and with a competitor. I found a negative effect of exotic conditioned soil on native growth and no effect of native conditioned soil on exotic growth, suggesting that plant-soil feedbacks may facilitate the establishment of the exotic as well as its dominance. Lastly, Chapter 6 investigated how seed addition and soil amendments management efforts affected native recovery after an extreme disturbance. I found that seed additions and soil N reductions were able to increase the establishment and fitness of some natives, but may not be sufficient to promote full native recovery. This work provides a tool to understand not only why native resident communities are invaded but also how to reduce the resistance of invaded communities and increase the resistance of native communities. Additionally this work allowed me to integrate the impacts that exotic species have on communities to make general predictions about the recovery of native communities after an extreme disturbance or control efforts. Overall, I observed that native communities and populations are vulnerable to invasion after a large disturbance and with nitrogen enrichment. From low to moderate nitrogen availability, native and exotic species should coexist due to niche partitioning, but not as a result of density dependent negative plant-soil feedbacks. Lastly, I found that an exotic species is able to maintain its dominance due to its strong competitive effect on native species, particularly at high nitrogen availability and its ability to culture a soil community that negatively impacts the growth of native species.

This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The California floristic province is home to a rich diversity of plant species, and the ecosystems they compose have a long and complex history of human management and anthropogenic disturbance. This is especially true of native grassland habitats, which have been burned, grazed, and replaced by agriculture and housing, and are now present in only a small fraction of the area they once covered. More recently, restoration and management activities increasingly seek to maintain and improve the plant diversity of California grasslands, but the effectiveness of typical strategies may alter under a changing climate. In this dissertation, I examined evidence of climate change effects on California grassland communities, the long-term effectiveness of livestock grazing as strategy to conserve native species, and the lessons that several decades of rare plant reintroductions have for future projects. In the first chapter, I used eight datasets collected over periods of 12 to 33 years to examine whether global climate change has altered California grassland vegetation communities. I used a metric known as the Community Temperature Index (CTI), which draws on historical species distribution records and spatial climate data to measure the relative dominance of species adapted to warmer and cooler temperatures within a location. I found evidence of long-term (1950-2019) increases in temperature and vapor pressure deficit at the sites I analyzed, though shorter-term study-period weather patterns were more variable. Six of the eight sites showed significant shifts in community composition towards warmer-climate species over time, and these increases occurred at faster rates than has been measured in other systems. Overall, the results suggest that some California grassland communities are shifting towards greater dominance by species adapted to warmer climates, but that these changes must be understood and interpreted within the history of abiotic conditions, long-term climate and weather history, and past land-use context of a site, as shorter-term weather patterns may not align with longer-term climate change and site conditions and past land management may exert a strong influence over community trajectory. My second chapter is focused on long-term grazing as a management strategy to maintain the diversity of native annual forbs in California coastal prairies in light of a recent historic drought and increasing temperatures. I resampled paired transects in eleven grazed and ungrazed sites from Monterey to Sonoma counties, California, 15 years after the original study. I found evidence to support the continued use of grazing to maintain higher native annual forb richness in coastal prairies, but also found that native annual forb richness had declined over 15 years in grazed prairies. Grazing continued to maintain low vegetation heights and thatch depths, and prevented shrub encroachment. I used circumstantial evidence from wetland indicator status and specific leaf area to support the hypothesis that severe drought and increasing aridity may be driving the declines in native annual forb richness that I measured, and explore how management and climate may interact to affect plant communities. In my third chapter, I synthesized lessons learned from reintroduction efforts for 14 listed plant species in California. Introductions and reintroductions of listed plant species are likely to be increasingly necessary in the future, so understanding how practitioners view their work and identifying persistent resource mismatches are key to the long-term viability of listed species. I interviewed practitioners to understand their definitions of recovery; how likely they felt recovery was; the advice they would share with other practitioners; and the resources they thought were lacking but that could make future projects more successful. I found that practitioners were generally guided by sound ecological theory and wanted to invest significant time and resources into understanding species biology and ecology, but that there were often barriers to success in the form of funding, time, and social constraints. Rare plant reintroductions are complicated by mismatches in timing and goals, but some individuals have been able to successfully navigate these challenges.
