GENERAL DESCRIPTION:
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_2014.shp

USER NOTES:
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.
GeoPlan relied on the integrity of the attribute information within
the original data.
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.

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.

The Florida Geographic Data Library is a collection of Geospatial Data
compiled by the University of Florida GeoPlan Center with support from
the Florida Department of Transportation. GIS data available in FGDL is
collected from various state, federal, and other agencies (data sources)
who are data stewards, producers, or publishers. The data available in
FGDL may not be the most current version of the data offered by the
data source. University of Florida GeoPlan Center makes no guarantees
about the currentness of the data and suggests that data users check
with the data source to see if more recent versions of the data exist.

Furthermore, the GIS data available in the FGDL are provided 'as is'.

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. For more information regarding

DATA LINEAGE SUMMARY:
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.
