This book was released on 2018 with total page 71 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Loss of wetland habitat and their associated services and functions during the past century has been extensive. As a solution, managers have turned to restoration, but even regionally, researchers lack agreement on monitoring criteria and analytical methods for defining restoration success. This study investigated the recovery trajectory of two recently restored wetlands in southern California as compared to a reference site using univariate, multivariate and equivalence analyses. Important abiotic and biotic parameters in the two restored marshes, such as salinity and invertebrate abundance, were equal or higher than the reference marsh using traditional simple hypothesis-based statistics like ANOVAs, indicating potential restoration success after 4 years. However, invertebrate community composition remained significantly using multivariate analysis. Inequivalence tests (an interval-based approach with reversed null hypothesis) indicated fewer parameters achieved restoration success, representing a more conservative approach. Overall, this demonstrates the need for long-term comprehensive monitoring that includes novel approaches to statistical analysis.

Available in PDF, EPUB and Kindle. Book excerpt: In order to combat the loss of valuable wetland functions and services, federal, state and tribal governments must have the tools to accurately assess and monitor the condition of wetland ecosystems. One particular method of wetland assessment is Floristic Quality Assessment (FQA), which has been growing in popularity throughout the United States since its creation in the 1970s. FQA relies on vegetative indicators of human disturbance to assess the integrity of an ecosystem. FQA calculations are based on Coefficients of Conservatism (C-scores), professionally-assigned scores ranging from 0-10 that denote a local species' tolerance to anthropogenic disturbance. Despite increasing interest in the use of FQA, few studies have thoroughly tested the performance of FQA, especially in New England. We used the Conservation Assessment and Prioritization System (CAPS), a landscape-based, coarse-scale assessment method, as a basis for evaluating FQA's performance in Massachusetts's forested wetlands. Our objective was to use CAPS Index of Ecological Integrity (IEI) scores (a form of generalized stressor gradient) to evaluate the performance of a variety of FQA indices (biological condition gradients), using C-scores from 7 states in the Northeast, and 2 ecoregions in Massachusetts. Based on our calculations of r-squared, and Spearman's rank analysis, we determined that FQA and C-scores have a moderate to weak relationship with the CAPS index of ecological integrity. Of the 12 indices and metrics we tested, the index with the strongest relationship to the IEI stressor gradient was mean Coefficient of Conservatism. Based on this research a number of suggestions are proposed for improving FQA as it applies to wetland assessment.

This book was released on 2010 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Depressional wetlands may be restored passively by disrupting prior drainage to recover original hydrology and relying on natural revegetation. Restored hydrology selects for wetland vegetation; however, depression geomorphology constrains the achievable hydroperiod, and plant communities are influenced by hydroperiod and available species pools. Such constraints can complicate assessments of restoration success. Sixteen drained depressions in South Carolina, USA, were restored experimentally by forest clearing and ditch plugging for potential crediting to a mitigation bank. Depressions were assigned to alternate revegetation methods representing desired targets of herbaceous and wet-forest communities. After five years, restoration progress and revegetation methods were evaluated. Restored hydroperiods differed among wetlands, but all sites developed diverse vegetation of native wetland species. Vegetation traits were influenced by hydroperiod and the effects of early drought, rather than by revegetation method. For mitigation banking, individual wetlands were assessed for improvement from pre-restoration condition and similarity to assigned reference type. Most wetlands met goals to increase hydroperiod, herb-species dominance, and wetland-plant composition. Fewer wetlands achieved equivalence to reference types because some vegetation targets were incompatible with depression hydroperiods and improbable without intensive management. The results illustrated a paradox in judging success when vegetation goals may be unsuited to system constraints.

Book excerpt: This is a preliminary evaluation of the status of the science of wetland creation and restoration in the United States. It contains a series of regional reviews. Each review summarizes wetland creation and restoration experiences in broadly defined wetland regions (e.g. Pacific coastal wetlands, wooded wetlands of the Southeast). It also includes a series of theme papers, covering a wide range of topics of general application to wetland creation and restoration (hydrology, management techniques, planning).
