<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本土及外来鱼类种群可能栖息的适宜生境区域。其中“当前”定义为过去5个繁殖周期以内；历史生境则指鱼类当前无法抵达，且在无人类干预的可预见未来也无法再度利用的适宜生境。

本数据集的信息基于采样调查、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出具的最佳专业判断，或建模分析（详见fhdBasis字段）。由于洄游种群规模、水文条件及其他环境因素存在自然波动，部分已识别的生境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于2020年4月通过的《俄勒冈州鱼类栖息地分布数据标准》，标准文档可通过以下链接获取：https://www.oregon.gov/geo/standards/OregonFishHabitatDistributionDataStandard_v4.pdf。历史生境分布数据属于本标准的覆盖范畴，可通过生境利用类型（fhdUseType）属性进行识别；历史生境仅在当前可抵达生境的范围外标注，且并非全覆盖。

溯河洄游及定居性鲑科鱼类的当前生境数据，整体完整性优于非猎用鱼类与外来鱼类物种的相关数据。所有数据集将随新信息的获取持续更新。

俄勒冈州鱼类栖息地分布数据的核心特征包括：物种、洄游类群、生活史类型、生境利用类型、起源、生产方式、每条记录的依据、数据创建者姓名、创建机构及参考文献。本分布数据以1:24000比例尺在全州范围内制图，其基础为全国水文数据集（National Hydrography Dataset, NHD）。

数据集以形状文件（shapefile）和ESRI地理数据库（ESRI geodatabase）两种GIS文件格式提供。本数据集的研发周期跨度为1996年至2024年，现基于全国水文数据集进行管理，并已同步至2021年12月版的NHD几何数据。本数据集涵盖17种本土洄游物种/类群，以及多种定居性物种。并非所有生境分布数据集均为全覆盖。
