Book Description
In dry, open coniferous forests of the montane West, stand-replacing wildfires and land use activities alter the composition and abundance of native grasses and forbs by degrading the habitat and accelerating the invasion of exotic annuals. On these lands, native forbs and grasses delayed or prevented from recovery by natural processes may require intervention through supplementary seeding. However, effective seeding of native plants requires that their seed traits and the potential outcome of the seeding be better understood. This study evaluated seeds and seedlings of 13 native forbs and 5 grasses common in the dry Pinus ponderosa/Purshia tridentata/ Festuca idahoensis plant communities east of the Oregon Cascades crest and their potential for establishment in a landscape altered by past grazing and a recent, stand-replacing wildfire. Their potential for germination and establishment was examined in the laboratory and in 20 test plots located within the burned boundary of a 2002 wildfire. Seed collection, handling, testing, and sowing procedures are described. Data on seedling emergence, height, second-year survival and cover are presented in tables and figures. Onsite emergence and early growth data helped to reveal cause of early mortality related to biological and site conditions, including invasive competition, and differences in early growth and site occupancy. The study supports the efficacy of using multiple and functionally diverse species in a seeding program. Additional information on each of the 18 species is included in an appendix.

Book Description
Bringing together ecology and management of invasive plants within natural and agricultural ecosystems, this book bridges the knowledge gap between the processes operating within ecosystems and the practices used to prevent, contain, control and eradicate invasive plant species. The book targets key processes that can be managed, the impact of invasive plants on these ecosystem processes and illustrates how adopting ecologically based principles can influence the ecosystem and lead to effective land management. It is suitable for researchers, practitioners and students of ecology, invasive spe.

Book Description
This long-anticipated reference and sourcebook for CaliforniaÕs remarkable ecological abundance provides an integrated assessment of each major ecosystem typeÑits distribution, structure, function, and management. A comprehensive synthesis of our knowledge about this biologically diverse state, Ecosystems of California covers the state from oceans to mountaintops using multiple lenses: past and present, flora and fauna, aquatic and terrestrial, natural and managed. Each chapter evaluates natural processes for a specific ecosystem, describes drivers of change, and discusses how that ecosystem may be altered in the future. This book also explores the drivers of CaliforniaÕs ecological patterns and the history of the stateÕs various ecosystems, outlining how the challenges of climate change and invasive species and opportunities for regulation and stewardship could potentially affect the stateÕs ecosystems. The text explicitly incorporates both human impacts and conservation and restoration efforts and shows how ecosystems support human well-being. Edited by two esteemed ecosystem ecologists and with overviews by leading experts on each ecosystem, this definitive work will be indispensable for natural resource management and conservation professionals as well as for undergraduate or graduate students of CaliforniaÕs environment and curious naturalists.
