Noxious Weeds Program Infestations

For more information about this layer please see the GIS Data Catalog. This dataset displays the known locations of noxious weed infestations across King County, Washington. It includes both active infestations, which are currently present and monitored, and non-active infestations, where weeds were previously reported but may have been controlled, eradicated, or require no further management at this time. Each infestation represents a geographic point or area where a regulated noxious weed species has been identified.Active infestations include sites where:A recent observation was identified.Ongoing management is planned or expected.There has been a confirmed presence within the current field season.Non-active infestations include sites where:Control efforts have been completed successfullyNo recent observations of the target weed existSites are considered under observation but with no active growth confirmedThe infestation status has been changed based on updated field inspections or landowner reportsThis dataset supports the King County Noxious Weed Control Program’s goal to track, monitor, and reduce the spread of invasive plant species harmful to agriculture, native ecosystems, recreation, and public health. Please note that infestation status reflects the most current information available but is subject to change based on seasonal fieldwork, reporting from landowners, and updated survey results. Infestation locations may vary in precision; some points represent approximate locations when detailed mapping was not available.如需了解该图层的更多信息，请参阅地理信息系统（Geographic Information System, GIS）数据目录。 本数据集展示了美国华盛顿州金县境内已知有害杂草入侵点的分布位置。本数据集涵盖活跃入侵点与非活跃入侵点两类：活跃入侵点指当前存在且处于监测中的入侵区域；非活跃入侵点则指此前曾有杂草上报记录，但目前可能已被防控、根除，或暂无需进一步治理的区域。 每一处入侵点均对应一处已确认存在管制类有害杂草物种的地理点位或区域。 活跃入侵点包含以下情形的区域： 1. 近期已完成观测并确认存在； 2. 正计划或预计开展后续治理工作； 3. 在当前生长季内已确认存在入侵杂草。 非活跃入侵点包含以下情形的区域： 1. 防控工作已顺利完成； 2. 近期未观测到目标杂草存在； 3. 区域处于监测状态，但未确认存在活跃生长的杂草； 4. 入侵点状态已根据最新野外巡查或土地所有者上报信息完成更新。 本数据集助力金县有害杂草防控项目达成目标：追踪、监测并抑制对农业、本土生态系统、休闲活动及公众健康造成危害的入侵植物的扩散。 请注意：入侵点状态基于当前可获取的最新信息更新，但可能会随季节性野外作业、土地所有者上报内容及最新调查结果发生变动。 入侵点的位置精度存在差异；当无法获取详细测绘数据时，部分点位仅代表近似位置。
