USER NOTES:
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.

A note concerning data scale:

Scale is an important factor in data usage. Certain scale 
datasetsare not suitable for some project, analysis, or
modelling 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.

1:250000 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 analyses. Every 
effort has been made to supply the user with data 
documentation. For additional information, see the 
References sectionand the Data Source Contact section of 
this documentation. For more information regarding scale 
and accuracy, see our web pages 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.
