USER NOTES:

These data appear to be logically consistent. No feature errors were identified

The data represents sites with known use by one of the seven species of mussels mapped. Mapped sites were identified based on survey results and the knowledge of biologists. Omissions may be possible due to the extent of coverage and difficulty of surveying all rivers and streams within the northeastern Gulf of Mexico drainages.

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 critical habitat units for the seven mussels. 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 Five Endangered and Two Threatened Mussels in Four Northeast Gulf of Mexico Drainages; [Final Rule 11/15/2007]. Final determination of critical habitat for seven listed mussels created under court order (Civil Action No. 1:04 CV-0729-GET).

Horizontal accuracy was not tested; however, data was created using USGS National Hydrography Dataset (NHD) at a scale of 1:100,000.

These data are not to be used in any way for legal or site-specific uses. The U.S. Fish and Wildlife Service is not responsible for any misuse or misinterpretation of these data. It is the responsibility of the user to use the data in an appropriate and consistent manner, recognizing its limitations.

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 purpose, or non-infringement. The University of Florida GeoPlan Center shall not be liable for any damages suffered as a result of using, modifying, contributing or distributing the materials. 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.

DATA LINEAGE SUMMARY:

Using mussel locations from source data, river reaches were selected from the NHD arc shapefiles and exported into a new shapefile. Biologists with expertise in current mussel occurrences reviewed the river reaches to identify missing streams or remove extra stream segments. New river reaches were added based on survey data received during the proposed critical habitat comment period. Fields were added to the attribute table for river distance (in meters, miles, and kilometers), unit name, unit number, and the species that occupy each unit. The upstream boundary of a unit in an occupied stream is the first perennial tributary confluence or first permanent barrier to fish passage (such as a dam) upstream of the upstream-most current occurrence record. The downstream boundary of a unit in an occupied stream is the mouth of the stream, the upstream extent of tidal influence, or the upstream extent of an impoundment, whichever comes first, downstream of the downstream-most occurrence record. Survey locations are typically at road crossings, because that is where surveyors can most easily gain access to the stream. These road crossings do not typically represent a meaningful ecological boundary for longitudinal stream habitat conditions. Data layers defining map units were created with USGS National Hydrography Dataset (NHD) GIS data. The 1:100,000 river reach (route) files were used to calculate river kilometers and miles. The following data sources were referenced to identify upstream and downstream extents of critical habitat units: USGS 7.5' quadrangles; Georgia Department of Transportation county highway maps; U.S. Census Bureau 1:100,000 TIGER line road data; 1993 Georgia digital orthographic quarter quads (DOQQs); 2004 Florida DOQQs; and DeLorme Atlas and Gazetteers for Alabama, Florida, and Georgia. The projection used in mapping all units was Universal Transverse Mercator (UTM), NAD 83, Zone 16 North. Process Date: 2006-2007 GeoPlan downloaded the data in October 2009 via the USFWS Critical Habitat portal in NAD_1983_UTM_Zone_16N Transverse Mercator projection. - Reprojected the dataset to FGDL Albers - Renamed dataset from 7mussels_ch to mussels_ch_nov07 - Upcased all fields - Added a DESCRIPT field based on NAME - Added FGDLAQDATE based on date FGDL acquired the data. Process Date: 20091104 Data imported to ArcSDE and exported as a shapefile. Process Date: 20091119
