Eradicating Invasive Plants that Threaten Salmon and Steelhead Habitat in the City and Borough of Juneau - Phase 2: Associated Data

Spatial data associated with Alaska Sustainable Salmon Fund Project #56004: Eradicating Invasive Plants that Threaten Salmon and Steelhead Habitat in the City and Borough of Juneau - Phase 2 Data are available in a geodatabase and as geoJSON files. They contain feature layers for point and polygon invasive species occurrences collected between 2023-2025, a line feature with relevant anadromous streams, and a polygon feature with relevant wetlands. For more information about this project, see http://www.akssf.org/Default.aspx?id=5557 Reed canarygrass, Bohemian knotweed, European bird cherry, and European mountain ash are invasive plant species that are well-established in or near streams, wetlands, and riparian areas that sustain salmon and steelhead populations in the City and Borough of Juneau (CBJ). These invasive species can outcompete and displace native plant species that provide important ecological functions benefitting fishes and other aquatic organisms. This project will continue efforts to eradicate these invasive plant species where they directly and indirectly threaten salmon and steelhead habitat.与阿拉斯加可持续三文鱼基金项目#56004相关的空间数据集：朱诺市及自治市镇内威胁三文鱼与硬头鳟栖息地的入侵植物根除项目——第二阶段。 本数据集以地理数据库（geodatabase）和地理JSON（geoJSON）格式提供，包含2023-2025年采集的入侵物种点状、面状发生特征图层，一条关联溯河产卵溪流（anadromous streams）的线特征图层，以及一片关联湿地的面状特征图层。如需了解该项目更多详情，请访问http://www.akssf.org/Default.aspx?id=5557。 芦苇金丝雀草（Reed canarygrass）、波希米亚虎杖（Bohemian knotweed）、欧洲鸟樱桃（European bird cherry）与欧洲花楸（European mountain ash）为已在朱诺市及自治市镇（CBJ）内或其邻近溪流、湿地及维持三文鱼与硬头鳟种群的河岸带（riparian areas）广泛定植的入侵植物物种。此类入侵物种可通过竞争排斥本地植物，而本地植物可为鱼类及其他水生生物提供关键生态功能。本项目将持续推进相关工作，在直接或间接威胁三文鱼与硬头鳟栖息地的区域内根除上述入侵植物物种。
