资源简介:

This data set contains observations of wildlife species that are Endangered, Threatened, of Special Concern (ETSC), or tracked for some other reason by the Maine Department of Inland Fisheries and Wildlife (MDIFW). In most cases, each polygon represents a single observation with multiple observations in the same location represented by multiple, stacked polygons. The mapping around each location includes important habitats associated with the species that was observed there. The primary purpose of this data set is to flag areas where a consultation with MDIFW about a species is warranted. This layer is updated as new observations are made and, less frequently, to refine the habitat mapping. In some cases, observations are removed from the data set when they become too old to be relevant, are replaced by more accurate information, or otherwise no longer represent a significant observation for that species. The geographic distribution of observations for a species may or may not approximate the extent of its occurrence in Maine. Although some observations are from systematic, relatively comprehensive surveys, other surveys focused on areas where the species was expected to be found and some observations were simply opportunistic. Users should not assume that a lack of data in a particular area means that the species does not occur there. Similarly, some observations are incidental (e.g., dispersing juveniles) and may not indicate that a viable population of that species occurs there. Users are encouraged to contact MDIFW with any questions about a specific observation or species. Terms of Use These data are provided by the Maine Department of Inland Fisheries and Wildlife solely for individual use or the use of a company. These data may not be distributed or sold to other users without the written permission of the Commissioner of the Department of Inland Fisheries and Wildlife. Users must assume responsibility in determining the usability of this data for their purposes. Providing public access to wildlife habitat data is not intended as a substitute for consultation with MDIFW staff regarding permit applications or environmental reviews.

本数据集收录了由缅因州内陆渔业与野生动物局(Maine Department of Inland Fisheries and Wildlife,MDIFW)监测的濒危、受威胁或具有特殊保护关切的物种(Endangered, Threatened, of Special Concern,ETSC),以及因其他原因受追踪的野生生物物种的观测记录。多数情况下,单个多边形代表一次单一观测;同一地点的多次观测则以多个堆叠的多边形表示。各点位周边的制图范围涵盖了与观测物种相关的重要生境。本数据集的核心用途为标记需与缅因州内陆渔业与野生动物局开展物种相关咨询的区域。该图层会随新观测数据的获取进行更新,且会在较少频次下优化生境制图内容。在部分场景中,当观测记录过时不再具备参考价值、被更精准的信息替代,或不再能反映该物种的有效观测记录时,会将其从数据集中移除。某一物种的观测地理分布范围,未必能等同于其在缅因州的实际分布范围。尽管部分观测源自系统性、相对全面的普查,但其他普查仅聚焦于该物种预期存在的区域,且部分观测仅为偶然获取。用户不应仅凭特定区域无数据,就认定该物种不存在于此区域。同理,部分观测属于偶然记录(例如扩散中的幼体),未必能表明该区域存在该物种的可存活种群。若用户对特定观测记录或物种存在疑问,建议联系缅因州内陆渔业与野生动物局咨询。 使用条款 本数据集由缅因州内陆渔业与野生动物局提供,仅可用于个人或企业内部使用。未经该部门专员书面许可,不得将本数据集分发或转售给其他用户。用户需自行承担判断本数据集是否符合自身使用用途的责任。向公众开放野生生物生境数据,并非替代针对许可申请或环境审查咨询缅因州内陆渔业与野生动物局工作人员的流程。
