USER NOTES:
These data are believed to be logically consistent, though no tests were performed.
This dataset was created based on the narrative unit descriptions as listed in the 
Federal Register, 50 CFR Part 17, Designation of Critical Habitat for the Gulf 
Sturgeon; Final Rule, February 28, 2003. Omissions of river distributaries may be 
possible due to the extent of source data (NHD) and because a number of the 
smaller streams are not named and easily identifiable. Based on the legal narrative 
unit descriptions in the Federal Register, all distributaries are included; however, 
they may not be graphically represented in this dataset.
GeoPlan relied on the integrity of the attribute information within
the original data.
Critical habitat identifies specific areas that are essential to the conservation of a 
listed species, and that may require special management considerations or 
protection. Section 7(a)(2) of the Act requires that Federal agencies ensure that 
actions they fund, permit, or carry out are not likely to result in the destruction or 
adverse modification of critical habitat. The regulatory effect of the critical habitat 
designation does not extend beyond those activities funded, permitted, or carried 
out by Federal agencies. State or private actions, with no Federal involvement, are 
not affected.

This dataset is provided for illustrative purposes only. This dataset does NOT 
represent the legal definition of riverine critical habitat units for Gulf sturgeon. For 
the precise legal definition, please refer to the narrative unit descriptions as listed 
in the Federal Register, 50 CFR Part 17, Designation of Critical Habitat for the Gulf 
Sturgeon; Final Rule, February 28, 2003.

Horizontal accuracy was not tested; however, data was created using National 
Hydrography Dataset which is assumed to have horizontal accuracy.

Vertical accuracy was not tested.

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'.
The University of Florida GeoPlan Center makes no warranties, guaranties
or representations as to the truth, accuracy or completeness of the data
provided by the data sources. The University of Florida GeoPlan Center
makes no representations or warranties about the quality or suitability
of the materials, either expressly or implied, including but not limited
to any implied warranties of merchantability, fitness for a particular

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
scale and accuracy, see our webpage at:

DATA LINEAGE SUMMARY:
This data set was created using ArcView 3.2a
The process steps for creating the final Gulf sturgeon
riverine critical habitat units were:
1. NHD arc and route.reach files were brought into the view
for each basin covered by the final critical habitat.
2. Records in the route.reach files were selected by
querying on the name field. Additional unnamed records
(mainly distributaries) were selected within the view using
the selector tool.
3. Records in the arc files were selected using the "Select
by theme..." command, choosing all records that were
completely within the route.reach files. The selected
records were visually checked to ensure that only river
centerlines were included.
4. Using the X-Tools extension "merge themes" command, all
selected records from the NHD arc files were combined into
the stg_ch_final.shp file.
5. Distributaries that were not included in the NHD arc
files but were included in the Federal Register maps or
DeLorme state gazetteers were added to the shapefile with
on-screen digitizing.
6. Using the narrative unit descriptions from the Federal
Register, some arcs were spilt and parts were removed. This
only occurred in units where the highest river reach
included stopped at a road crossing. The roads layer used
to determine this stopping point is from the ESRI Sample
Data and Maps, CD Volume 5, Southern U.S., August 1999.

GeoPlan downloaded this data from http://criticalhabitat.fws.gov/ in January of 2009. The layer was originally in GCS NAD83 projection. This layer updates an existing layer in FGDL called GULF_STURGEON_L. The layer that already existed in FGDL did not match the new layer downloaded. We contacted Wendy_Gierhart@fws.gov and she helped us determine that the layer we had in FGDL needed to be updated. -Upcased all records -Added Descript field based on NAME field -Added FGDLAQDATE -Deleted OBJECTID field -Projected to FGDL Albers -Rename from gulf_sturgeon_lines.shp to GULF_STURGEON_L_CH Process Date: 20090123
