Seagrass Habitat in Florida

This polygon GIS data set represents a compilation of statewide seagrass data from various source agencies and scales. The data were mapped from sources ranging in date from 1987 to 2025. This dataset is complete as of data available to FWRI in June 2026. Not all data in this compilation are mapped from photography; some are the results of field measurements. See the "Sources" section for more information. The original source data sets were not all classified in the same manner; some used the Florida Land Use Cover and Forms Classification System (FLUCCS) codes 9113 for discontinuous seagrass and 9116 for continuous seagrass; some defined only presence and absence of seagrass, and some defined varying degrees of seagrass percent cover. In order to merge all of these data sources into one compilation data set, FWRI reclassified the various source data attribute schemes into two categories: "Continuous Seagrass" and "Patchy (Discontinuous) Seagrass". In areas where studies overlap, the most recent study where a given area has been interpreted is represented in this data set. This data set is not comparable to previous statewide data sets for time series studies - not all areas have been updated since the previous statewide compilation and some areas previously not mapped are now included. Please contact GIS Librarian to request the source data if you need to do a time series comparison. This data set has been updated in several areas from the previous compilation, including Naples Bay (2007), Big Bend (2022), Choctawhatchee Bay (2017), Pensacola Bay/Santa Rosa Bay/Big Lagoon (2017), Perdido Bay (2017), and St. Andrew Bay (2024), St. Joseph Bay (2024), Florida Bay (2016), portions of the Caloosahatchee, Loxahatchee, and St. Lucie Rivers (2011), Lake Worth Lagoon (2023), Rookery Bay (2014), Estero Bay and the West Coast (2021), Lake Worth Lagoon (2023), Indian River Lagoon (2025), Sunken Island (2023), the Springs Coast (2024) and Southwest Florida (2024). Version 2 of the Unified Florida Reef Tract Map, with seagrass data ranging in source date from 2004-2015, has also been integrated into this compilation to represent the most recent data available from St. Lucie County to the Dry Tortugas in Florida Keys.本多边形地理信息系统（GIS）数据集整合了来自不同来源机构、不同尺度的全州海草数据。所有数据源的时间跨度为1987年至2025年。本数据集的更新截止至2026年6月FWRI可获取的所有数据。 本汇编中的部分数据并非通过影像解译获取，另有一部分来自实地测量结果，详细信息请参见"Sources"章节。 原始源数据集的分类标准并不统一：部分数据集采用佛罗里达土地利用覆盖与形态分类系统（FLUCCS）的9113编码表示非连续性海草，9116编码表示连续性海草；部分数据集仅标注海草的存在与缺失状态，还有部分数据集划分了不同程度的海草盖度百分比。为将各类源数据集整合为统一汇编数据集，FWRI将各源数据的属性分类方案重新归类为两类："Continuous Seagrass"（连续性海草）与"Patchy (Discontinuous) Seagrass"（斑块状（非连续性）海草）。 在研究区域重叠的区域，本数据集采用对该区域进行解译的最新研究成果。本数据集不可与此前的全州海草数据集直接用于时间序列对比：并非所有区域都完成了更新以适配此前的全州汇编数据，且部分此前未完成制图的区域现已纳入本数据集。若需开展时间序列对比研究，请联系GIS馆员获取源数据集。 本数据集在多个区域相较于此前的汇编版本完成了更新，包括那不勒斯湾（2007年）、大本德地区（2022年）、乔克托哈奇湾（2017年）、彭萨科拉湾/圣罗莎湾/大泻湖（2017年）、佩尔迪多湾（2017年）以及圣安德鲁湾（2024年）、圣约瑟夫湾（2024年）、佛罗里达湾（2016年）、卡卢萨哈奇河、洛萨哈奇河与圣露西河部分河段（2011年）、沃思湖潟湖（2023年）、鲁克里湾（2014年）、埃斯特罗湾与西海岸（2021年）、沃思湖潟湖（2023年）、印第安河潟湖（2025年）、沉岛（2023年）、斯普林斯海岸（2024年）与西南佛罗里达地区（2024年）。 《统一佛罗里达礁区地图》第二版（其海草数据源时间跨度为2004年至2015年）也已整合至本汇编数据集，用于呈现佛罗里达礁区从圣露西县至德赖托图格斯群岛的最新可用数据。
