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.

Download Light Level as a Potential Limiting Factor in the Growth of Zostera Marina Eelgrass in the Pacific Northwest Book in PDF, ePub and Kindle
From Abstract: Eelgrasses serve as important nursery habitats in the Pacific Northwest for diverse marine life and are widely recognized as indicators of coastal ecological health. Seasonal differences in respiration and Photosynthesis-Irradiance (P-I) relationships of a population of marine eelgrass Zostera marina in Rosario Bay, WA were investigated in order to characterize its growth potential in different seasons. The local light availability in situ for each season was also estimated by combining direct light measurements under different conditions with hourly weather and tide measurements. Measurement of the P-I relationship of blade sections and extrapolation to whole plants demonstrated that sufficient light is present even in the lowest-light season (winter) so that clean eelgrass is able to at least support its metabolism by photosynthesis and experience net growth. However, epiphytic algae living on the blades of Z. marina likely reduces its access to light, especially in summer, and could potentially lead to light limiting conditions.
