Title Riparian Buffer Classification for streams in the Upper Little Tennessee River watershed, NC.
Archive All Files / GIS Vector Data / General GIS Data / Stream Networks
Description

This data set includes riparian buffer classifications for streams in the Upper Little Tennessee River Watershed that were developed from the corrected streams data set. Riparian buffer classifications were not developed for streams occurring in Nantahala National Forest. The corrected streams data set includes streams mapped by the NC Stream Mapping Program (NCSMP) that have been corrected based on their presence or absence as observed in 2006 aerial imagery. Streams mapped by the NCSMP were downloaded from http://www.ncstreams.org/DataAccess/tabid/257/Default.aspx and corrected using aerial photography for Swain and Macon Counties dated 2006 that were obtained by EEP.

Four classes of riparian buffer widths were created based on the presence or absence of woody vegetation in the riparian area as viewed in the 2006 aerial photos. Right and left banks were analyzed separately and include the following classes:

1 = < 30 feet

2 = 30-100 feet

3= > 100 feet, and

4 = underground

This data set is intended to characterize riparian buffer conditions for streams in the Upper Little Tennessee River Watershed. The riparian buffer classification data set is believed to provide a reasonable basis for generalizing about sub-watershed and watershed conditions. Riparian buffer classification is also one of the key data sets used to determine aquatic function and stream rehabilitation project potential.

This data set provides an initial estimate of likely riparian buffer conditions, but a field examination of the area in question is recommended if accurate information on the current buffer status of specific reaches or properties is desired.
