This dataset contains watershed locations of rare and imperiled fish collections compiled from various sources. Maintaining aquatic ecosystem health is critical for the conservation of a number of rare and imperiled freshwater mussel and fish species. This project employed Geographic Information System (GIS) models to rapidly evaluate and broadly describe streams based upon systemizing up-to-date statewide multi-scale spatial data capable of characterizing aquatic species habitats. Main data sets that were used to attribute the stream network included climate, ecoregions, ecological drainage units, and HUC-12 watersheds. We developed a statewide stream habitat classification GIS data layer that is necessary for the identification of existing and potential habitats of aquatic species. The classification scheme used a set of hierarchical stream habitat abiotic characteristics presumably correlated with the fine-scale stream characteristics important for aquatic species. The nested aquatic classification system crosses landscape-level ecosystem/hydrologic units for freshwater areas. The freshwater aquatic habitat classification provides adequate detail for conducting ecological GIS modeling and large- scale statewide and ecoregional assessments, finer watershed level assessments, as well as assessments at a scale of individual stream segments. This is an update to the FGDL layer rarimpwaters_2016.shp
The objective of this project was to develop thea digital stream habitat classification data layer that is necessary for the identification of existing and potential habitats of rare and imperiled fish and other aquatic species. This Florida Fish and Wildlife Conservation Commission SWG project Florida Stream Habitat Classification involved the application of the stream habitat classification framework to attribute the HUC-12 Florida Watershed Boundary Database on subwatershed level from the Perdido River to the Everglades.
Prior to July 1, 2004, the Fish and Wildlife Research Institute (FWRI) was known as the Florida Marine Research Institute (FMRI). The institute name has not been changed in historical data sets or references to work completed by the Florida Marine Research Institute. The institute name has been changed in references to ongoing research, new research, and contact information.

GeoPlan relied on the integrity of the attribute information within the original data.
We decided to consider basins that had the similarity index of 89.5% or greater as belonging to a particular EDU.
Overall, there are 53 combinations of Ecosubregions/Climate/EDU in Florida. However, there are only 44 complete combinations because 9 are missing fish data for the EDUs along the east coast.

Spatial and Attribute Information
The process involved coding the river and stream network with aquatic characteristics at multiple scales using external and internally developed data sources. The components were delineated across ecoregional province and section, climate regions, land-cover types, and groundwater level and substrate type (based on surficial geology and soil types). Once the corresponding source layers were prepared as described below, they were intersected with the FL Stream Habitat Classification (FSHC) using the ESRI ArcTool "Identity". This operation split the FSHC lines by the intersecting areas, and at the same time, the classification attributes were added to the FSHC. The Climate divisions, Ecosubregions, Ecological Drainage Units, and HUC-12 were also overlaid with each other. Climate divisions and Ecosubregions boundaries were adjusted to HUC-8 boundaries in most of the cases. In cases where this was not possible, the more detailed HUC boundaries served for the adjustments of the Aquatic Subregions. A total of 256 fish species, by 42 drainages of the Southeastern United States, was imported into Primer 5 version 5.2.9 (PRIMER-E Ltd, Roborough, Plymouth, UK), a multivariate statistics package for ecologists. All of the species present in a basin class (native freshwater species, native freshwater species and possibly introduced, euryhaline species, and suspected records without known museum records or other substantiation) were given a score of 1 in the table and all empty cells, indicating absence of the species, were given a 0 score. The Bray-Curtis similarity matrix was created for the drainages. A hierarchical cluster analysis with a dendrogram and a multidimensional scaling (MDS) plot were preformed on the similarity index. The index was used to make a decision of how to combine the drainages into EDUs. We decided to consider basins that had the similarity index of 89.5% or greater as belonging to a particular EDU. This means that an EDU had basins that were 89.5% similar in species composition. The 89.5% cutoff combined the 42 original basins into 18 distinctive Ecological Drainage Units of the Southeastern United States. The EDUs were included in HUCs-8 not only in Florida but also from Lake Ponchartrain to Savannah River within NHD subregions 0306, 0315, 0318, 0807 and 0809. The NHD HUC-8 boundaries outside of Florida were adjusted to the HUC-12 boundaries. There were 9 EDUs in Florida, with a gap along the Atlantic coast for which there were no source data. The original HUC-12 shapefile with more than 4,000 polygons contained many gaps and overlays. We used the ET Geowizard ArcGIS extension to clean the layer of overlays and eliminate the gaps by joining them to the largest adjacent HUC. Remaining small sliver polygons were deleted using a 0.1 m tolerance. This process reduced the number of polygons to 1,575. After joining to it the NHD HUCs-8 encompassing the Southeastern US EDUs, there were 1,706 polygons in the final shapefile. We used the 7 Florida climate divisions developed by University of Florida and subdivided it by county boundaries. We used the 3 ecoregions and 14 eco-subregions of Florida developed by EPA and DEP. Overall, there are 53 combinations of Ecosubregions/Climate/EDU in Florida. However, there are only 44 complete combinations because 9 are missing fish data for the EDUs along the east coast.
GeoPlan was provided the data in shapefile format via email by FFWCC/FWRI on June 14th, 2019. Eva Salinas GIS Data Manager Florida Fish and Wildlife Conservation Commission Fish and Wildlife Research Institute Center for Spatial Analysis 620 South Meridian St., Tallahassee, Fl 32399 Office: (850) 488-8797 GIS.Requests@myfwc.com The GeoPlan Center took the following steps during the QA/QC process: - Dataset projected into FGDL Albers HPGN projection. - turned off the following fields: AREA, PERIMETER - DESCRIPT field added based on HUC12 Code Name which was gathered from the USGS Watershed Boundary Dataset (WBD). This dataset was downloaded from here: https://nhd.usgs.gov/wbd.html - Polgygons with different or old HUC12 Code Name ID's had their DESCRIPT fields calculated as 'NO DESCRIPT AVAILABLE" - FGDLAQDATE field was added based on the date the dataset was received. - The longest record for each field was found and field character lengths were shortened to the appropriate shortest length possible. - Uppercased fields and records in the dataset. - Layer name changed from rarimpwaters_update.shp to rarimpwaters_2019.shp.

A note about data scale: Scale is an important factor in data usage. Certain scale datasets are not suitable for some project, analysis, or modeling purposes. Please be sure you are using the best available data. 1:24000 scale datasets are recommended for projects that are at the county level. 1:24000 data should NOT be used for high accuracy base mapping such as property parcel boundaries. 1:100000 scale datasets are recommended for projects that are at the multi-county or regional level. 1:125000 scale datasets are recommended for projects that are at the regional or state level or larger. Vector datasets with no defined scale or accuracy should be considered suspect. Make sure you are familiar with your data before using it for projects or analysis. Every effort has been made to supply the user with data documentation. For additional information, see the References section and the Data Source Contact section of this documentation.
