This book was released on 2002 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Eelgrass meadows provide important habitat for many species of commercially and recreationally important finfish and shellfish. Unfortunately, a great deal of eelgrass habitat has been lost in recent years. Restoration of eelgrass can be successful, however, the present techniques of transplanting whole plants are costly and disruptive to healthy donor beds. This project is developing methods to use eelgrass seeds as a practical and affordable alternative to present restoration techniques and to develop a mechanized underwater seed planter capable of efficiently planting large areas with eelgrass seed. The project will also produce a practical "how to" guide for the collection, separation and storage of seeds. A second guide will describe seeding strategies, which achieved the highest success at field sites within the National Estuarine Research Reserve. The technology developed can be transferred directly to restoration efforts in other estuaries.

This book was released on 2008-01-12 with total page 577 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the U.S., approximately two-thirds of the coastal rivers and bays are moderately to severely degraded from nutrient pollution. The contributors to this book use long-term data sets to discuss the interactions among biological, ecological, chemical, and physical processes, and discuss what is known about nutrient inputs to the bay ecosystem, the impacts related to nutrient inputs, and how the ecosystem might respond to a sudden reduction in these inputs.

This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper explores recovery of eelgrass (Zostera marina L.) meadows through seed-based restoration to address declines from natural and anthropogenic disturbances. The study focuses on the Joe Leary meadow site in Padilla Bay, Washington, aiming to (1) determine the spatial distribution of perennial and annual Z. marina, (2) understand variation in flowering shoot density and potential seed production, and (3) compare the phenology of flowering shoots. These objectives were investigated using field-based methods to collect presence/absence transect data for delineation, quadrat-based count data, and monitor seed development. Data collection occurred in the summer throughout the flowering life stage of eelgrass in the site. The study found spatial and temporal variation in the distribution, density, and phenology of flowering perennial and annual populations. Delineation methods revealed that annuals have a similar range in the intertidal as perennials, with differences highlighted in response to potential stress indicators such as proximity to the slough, algal mats, or elevation. Quadrat-based monitoring found annual shoots in the transect higher in the intertidal, above the perennial population. Phenology data indicated that perennial shoots flower about a month prior to annual shoots. While the study advises against using perennial flowering shoots for restoration due to low densities, it emphasizes Joe Leary's potential as a donor site for flowering annuals for seed-based restoration. Careful considerations are crucial to avoid unintended introductions of non-native species. The research concludes with recommendations for refining delineation methods, enhancing understanding of eelgrass population dynamics, and optimizing seed collection strategies for genetically diverse and resilient restoration in the face of climate change.

Available in PDF, EPUB and Kindle. Book excerpt: We summarize eelgrass (Zostera marina L.) restoration and mitigation project results and recommendations of transplant practitioners in the Pacific Northwest since 1990. Our purpose is to provide current information for programs considering eelgrass restoration by providing a synthesis of what practitioners and researchers have learned through experimentation and monitoring of discrete projects throughout western Washington and British Columbia. Reports, papers, personal communications, and a workshop were used to gather data on these projects. Our general null hypothesis is that eelgrass can be restored to match natural eelgrass meadows in terms of structure and function. We conclude that, under favorable site conditions, and if the reason for the initial loss of eelgrass is understood and corrected, that eelgrass can be restored. However, eelgrass restoration science is hampered by knowledge gaps, reducing restoration success. For example, mechanisms for recent eelgrass loss in the region are not obvious, which suggests that the scientific understanding of eelgrass biology and ecosystem conditions is inadequate to support environmental management actions in our region. To improve restoration project success in the Pacific Northwest requires further research knowledge gaps, closely evaluating the performance of restoration projects, and disseminating information for use by future generations. Workshop participants identified an immediate need to construct a clearinghouse of eelgrass restoration and monitoring results that provides summaries and data from eelgrass enhancement efforts. Furthermore, we found that it was difficult to summarize the relative performance of the more than 30 projects reviewed because of variations in goals, project size, planting methods employed, performance criteria, duration of monitoring, intensity of monitoring, and data interpretation. Hence, we recommend that standard monitoring protocols be developed and results from .these methods be reported through the clearinghouse and periodic meetings.
