Without the protective barrier, the area of vegetated wetland was reduced by wave attack. Lake-level regulation implemented in 1960 resulted in cattail (primarily hybrid Typha × glauca), invasion and loss of sedge-grass meadow habitat. As part of the Rochester Embayment Great Lakes Area of Concern, Braddock Bay was targeted for restoration by the U.S. Army Corps of Engineers. The plan included reducing coverage by cattails, construction of channels and potholes to improve wildlife access to the wetland, creation of spoil mounds along the channels to discourage growth of cattail while supporting the growth of sedge-grass meadow species, re-creation of the barrier beach, and construction of new emergent marsh. We collected vegetation data for three years following the 2016 construction activities. Post-restoration results showed that cattail cover decreased greatly across years in the cattail treatment areas, decreased in lower elevation constructed habitats, and gradually increased in higher elevation habitats. Opening of the canopy resulted in increased floating and submersed species, and constructed mounds hosted wet meadow species. Site-level weighted mean C is recommended for future data analyses, rather than FQAI or mean C, because it has no observed influence from species richness. Restoration results were affected by high lake levels in 2017, identified problems in seeding and planting, and meeting construction plans for some channel and pothole depths and mound elevations. Pre-restoration soil surveys are recommended to reduce construction problems, and adaptive management should include invasive species control.","PeriodicalId":11492,"journal":{"name":"Ecological Restoration","volume":"39 1","pages":"247 - 259"},"PeriodicalIF":1.6,"publicationDate":"2021-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45740699","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

International efforts to restore freshwater ecosystems, along with increased stress on hydraulic structures due to climate change-induced flooding, extreme rain events, and sea-level rise, have resulted in increased incidences of breaching and removal of these structures. However, modification of hydraulic structures can facilitate the dispersal of aquatic invasive species. Such an unintended outcome became apparent following the replacement of an ageing earthen dam at Greenburn Lake (South Pender Island, British Columbia) that appears to have facilitated the spread of Iris pseudacorus (Yellow flag iris) into previously uninvaded wetland habitat. While best practices to prevent this plant’s downstream dispersal were implemented, the observed spread offers several practical recommendations to mitigate this risk in similar projects. We recommend that aquatic invasive species be explicitly considered prior to construction as part of an environmental impact assessment. Specifically, the spread of I. pseudacorus could have been mitigated through 1) enhanced efforts to clean machinery and equipment, 2) timely off-site disposal of organic material and sediment containing reproductive propagules, 3) cutting and smothering of I. pseudacorus within the work area at minimum three months before construction, 4) shifting timing of construction to fit within ecologically defined work windows that minimize the spread of I. pseudacorus seeds, and 5) use of physical barriers to capture suspended and buoyant propagules. The utilization of similar methods may reduce the spread of aquatic invasive plants during the maintenance or removal of other hydraulic structures.","PeriodicalId":11492,"journal":{"name":"Ecological Restoration","volume":"39 1","pages":"238 - 246"},"PeriodicalIF":1.6,"publicationDate":"2021-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44515304","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Since then, the state’s collaborative program has conducted approximately 20 projects. Most consisted of constructing a hard substrate (usually mollusc shells) reef base then adding live juvenile oysters (“spat-on-shell”) produced in remote setting tanks. Assessments conducted in 2013, 2015, and 2019 provided long-term (up to 13 years post-construction) data on success and identified potential improvements to the restoration protocol involving two design criteria: reef base and site location. All three long-term assessments found excessive base burial (sedimentation) at many sites, leading to attempts to balance base height, bottom area coverage, and available funds. The result for most projects was multiple, haphazardly positioned shell mounds extending < 0.5 m above the bottom. The site location process initially focused on areas where oyster reefs occurred historically, but after the 2013 assessment and subsequent field experiments, the focus changed to identifying areas with the highest potential for recruitment from wild oysters. This research, which involved three natural reefs over two years, found > 75% of total recruitment occurred < 400 m from the natural reefs. Most current restoration projects center around these two design criteria: multiple shell mound structure and proximity to a healthy natural reef. The New Hampshire experience thus far confirms the emphasis by others on the value of long-term assessments, but as is the case in most areas, much remains to be learned and accomplished.","PeriodicalId":11492,"journal":{"name":"Ecological Restoration","volume":"39 1","pages":"260 - 273"},"PeriodicalIF":1.6,"publicationDate":"2021-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48976219","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
