<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>Oregon Fish Habitat Oregon Fish Habitat Distribution. These data describe areas of suitable habitat believed to be used currently or historically by native or non-native fish populations. The term "currently" is defined as within the past five reproductive cycles. Historical habitat includes suitable habitat that fish no longer access and will not access in the foreseeable future without human intervention. This information is based on sampling, the best professional opinion of Oregon Dept. of Fish and Wildlife or other natural resources agency staff biologists or modeling (see the fhdBasis field). Due to natural variations in run size, water conditions, or other environmental factors, some habitats identified may not be used annually. These data now comply with the Oregon Fish Habitat Distribution Data Standard that was adopted by the Oregon Geographic Information Council in April 2020. The Standard document can be found at: https://www.oregon.gov/geo/standards/OregonFishHabitatDistributionDataStandard_v4.pdf. Historical habitat distribution data are within the scope of the standard and are identified via the habitat use (fhdUseType) attribute. Historical habitats are only identified outside of currently accessible habitat and are not comprehensive. Data representing current habitat for anadromous and resident salmonid species are generally more comprehensive than data for non-game and non-native fish species. All datasets are subject to update as new information becomes available. Key features of the Oregon Fish Habitat Distribution Data include: species, run, life history, habitat use, origin, production, the basis for each record, originator name, originator entity and reference. Habitat distribution data are mapped at a 1:24,000 scale statewide and are based on the National Hydrography dataset. The data are made available as GIS files in both shapefile and ESRI geodatabase format. The data were developed over an extensive time period ranging from 1996 to 2024. The data are now managed on the National Hydrography Dataset and have been synchronized to December 2021 NHD geometry.Distribution for seventeen native migratory species / runs, including numerous resident species. Not all habitat distribution datasets are comprehensive.</SPAN></P></DIV></DIV></DIV>

俄勒冈州鱼类栖息地分布数据集。本数据集描述了当前或历史上被本土及外来鱼类种群所利用的适宜栖息区域。“当前”的定义为过去五个繁殖周期以内。历史栖息地指鱼类现已无法进入，且在无人类干预的可预见未来也无法进入的适宜栖息区域。本数据集信息基于采样调查、俄勒冈州鱼类与野生动物局（Oregon Department of Fish and Wildlife）或其他自然资源机构的专业生物学家的权威意见，或是模型推演（详见fhdBasis字段）。由于洄游种群规模、水文条件及其他环境因素的自然波动，部分已识别的栖息区域可能并非每年都会被鱼类利用。本数据集现已符合俄勒冈州地理信息委员会（Oregon Geographic Information Council）于2020年4月通过的《俄勒冈州鱼类栖息地分布数据标准》。该标准文档可通过以下链接获取：https://www.oregon.gov/geo/standards/OregonFishHabitatDistributionDataStandard_v4.pdf。历史栖息地分布数据属于本标准的覆盖范围，可通过栖息地利用类型（fhdUseType）属性进行识别。历史栖息地仅会在当前可进入栖息地以外的区域被识别，且数据集并非全覆盖。洄游性及定居性鲑形目鱼类的当前栖息区域数据，通常较非猎用鱼类及外来鱼类的栖息区域数据更为全面。所有数据集将随新信息的获取随时更新。俄勒冈州鱼类栖息地分布数据集的核心字段包括：物种、洄游类群、生活史类型、栖息地利用类型、起源属性、种群生产属性、单条记录的依据来源、数据创建者姓名、创建机构及参考文献。本数据集以全州1:24000比例尺进行制图，其基底为国家水文数据集（National Hydrography Dataset）。数据集以GIS文件格式发布，包含shapefile与ESRI geodatabase两种格式。本数据集的编制周期跨度达1996年至2024年。当前数据集依托国家水文数据集进行管理，并已同步至2021年12月版的NHD空间几何数据。数据集覆盖17种本土洄游鱼类/洄游类群，以及多种定居性鱼类。并非所有栖息区域分布数据集均为全覆盖状态。
