Download or read book Ecosystem Recovery in Estuarine Wetlands of the Columbia River Estuary written by and published by . This book was released on 2017 with total page 325 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the restoration of tidal wetland ecosystems, potential drivers of plant community development range from biotic controls (e.g. plant competition, seed dispersal) to abiotic controls (e.g. tidal flooding, salinity levels). How these controls influence the success of tidal wetland restoration are only partly understood, but have important implications for wetland habitat recovery. Specifically, the extent to which the existing native and non-native seed banks in tidally reconnected wetlands interact with these controls is not clear, yet the potential success of passive restoration methods depends upon this understanding. For a 54-year chronosequence of eleven tidal wetland restoration sites in the Lower Columbia River of western Oregon, USA, it was hypothesized that native plant species and soil properties would show trends approaching reference levels within 3 to 20 years post-restoration and that lower elevation wetland areas within restored sites would exhibit a greater native species abundance and similarity to reference sites, compared with restored high elevation wetland areas. Results indicated that plant species richness, soil organic matter, bulk density, pH, and salinity conditions among the restoration sites reached reference wetland ranges within 3-6 years post-tidal reconnection. The mid-low marsh elevation zones (2.5 m) remained dominated by non-native species Phalaris arundinacea and Juncus effusus subsp. effusus. To investigate the mechanisms driving these non-native plant invasions, it was hypothesized that native and non-native wetland plant community distributions would be reflective both of their abundance in the seed bank and of their germination tolerance to wetland tidal flooding and salinity conditions. Using a factorial study design of three tidal conditions by three salinity levels, these hypotheses were tested in the greenhouse. Overall, non-native seeds were found to significantly outnumber native seeds in both seed banks. In the greenhouse, P. arundinacea and J. effusus were found to germinate more readily out of the seed bank under freshwater high-marsh flooding (1 hour a day) treatments as compared to oligohaline (3 ppt) mid-low marsh flooding (3-6 hours twice a day) treatments and to brackish salinity (10 ppt) treatments. Dominant native wetland species, Carex lyngbyei and Schoenoplectus lacustris, germination were not found to vary significantly among the treatments (p > 0.10). These results indicate that the salinity and flooding gradients within these restored marshes suppress germination of the non-native species in the low-mid marsh but not in the high marsh, where they are likely able to outcompete the native species due to their dominance in the seed bank. The implications of these results for passive tidal wetland restoration efforts are that both seed bank composition and species-specific tolerances to restored tidal flooding and salinity gradients are key mechanisms driving native and non-native plant community development and resilience.

Download or read book Assessing Community Support and the Potential for Community based Partnerships in the Restoration of the Cache River Wetlands written by Christopher A. Bridges and published by . This book was released on 2007 with total page 346 pages. Available in PDF, EPUB and Kindle. Book excerpt: Community-based ecosystem restoration efforts have emerged throughout North America, largely driven by the collective action of local stakeholders. While the need for greater integration of collaborative processes into natural resource management has been demonstrated extensively by researchers, few studies have addressed how to develop long-term conservation partnerships that are able to sustain extensive restoration projects. The ecologically distinct Cache River Wetlands are located in southern Illinois, near the convergence of the Mississippi and Ohio Rivers. In the late 1970s, extensive wetlands drainage and land conversion for agricultural production motivated local community members to organize and preserve remnants of the wetlands and to work towards restoration of the Cache River Wetlands ecosystem. Community efforts captured the attention of natural resource management agencies and organizations, including the Illinois Department of Natural Resources, The Nature Conservancy, Ducks Unlimited, US Fish and Wildlife Service and USDA Natural Resource Conservation Service. The synergy created by these agencies in the early 1990s prompted the formation of the Cache River Joint Venture Partnership and the goal of restoring a 60,000 acre forest and wetland corridor. While several local advocacy groups have been active in restoration, managers have struggled to sustain involvement and support throughout the greater community. This study used a qualitative research framework to: (1) Assess community stakeholder attitudes toward ecosystem restoration; (2) Identify barriers and potential incentives for enhancing meaningful community participation in ecosystem restoration; and (3) Develop partnership-building recommendations for natural resource managers in the Cache River Wetlands. Data collected through in-depth personal interviews with 25 community stakeholder representatives revealed that although study participants display favorable attitudes toward ecological restoration, stakeholders perceive community members' limited awareness of restoration programs, time constraints and regional economic depression as limiting involvement. The varied meanings that different stakeholder groups attribute to the wetlands appear to influence both attitudes toward restoration and reported levels of participation. A typology of stakeholder groups is presented based on their capacity to get involved that illustrates the potential for environmental education and outreach efforts to inspire participation. To facilitate collective community action in restoration, Cache River wetlands managers must connect restoration actions with significant community goals.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: Invasive non-native species are a major threat to global biodiversity. Often introduced accidentally through international travel or trade, they invade and colonize new habitats, often with devastating consequences for the local flora and fauna. Their environmental impacts can range from damage to resource production (e.g. agriculture and forestry) and infrastructure (e.g. buildings, road and water supply), to human health. They consequently can have major economic impacts. It is a priority to prevent their introduction and spread, as well as to control them. Freshwater ecosystems are particularly at risk from invasions and are landscape corridors that facilitate the spread of invasives. This book reviews the current state of knowledge of the most notable global invasive freshwater species or groups, based on their severity of economic impact, geographic distribution outside of their native range, extent of research, and recognition of the ecological severity of the impact of the species by the IUCN. As well as some of the very well-known species, the book also covers some invasives that are emerging as serious threats. Examples covered include a range of aquatic and riparian plants, insects, molluscs, crustacea, fish, amphibians, reptiles and mammals, as well as some major pathogens of aquatic organisms. The book also includes overview chapters synthesizing the ecological impact of invasive species in fresh water and summarizing practical implications for the management of rivers and other freshwater habitats.

Download or read book From the Sierra to the Sea written by William S. Alevizon and published by Bookbaby. This book was released on 2018 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The original report From the Sierra to the Sea: Ecological History of the San Francisco Bay-Delta Watershed was a product of a three-year effort to develop a landscape level overview of the natural ecological structure, function and organization of the watershed, and the way it had changed over the course of the 19th and 20th centuries. Technical review and contributions from government and water agencies helped produce a collaborative document that provided information on the historical ecological baseline in order to assist in what was envisioned at the time as the most ambitious restoration effort ever undertaken in the United States. We are proud of the fact that the original document is still used as an objective reference, and has provided a foundation and inspiration for similar but more intensively researched localized efforts by others in the Bay-Delta watershed. This 20th anniversary edition contains a new Afterword describing changes to the estuary and its watershed since the report was originally published in 1998.
