Geospatial data for the Vegetation Mapping Inventory Project of Alibates Flint Quarries National Monument and Lake Meredith National Recreation Area
The files linked to this reference are the geospatial data created as part of the completion of the baseline vegetation inventory project for the NPS park unit. Current format is ArcGIS file geodatabase but older formats may exist as shapefiles.
A total of 88,479 acres (35,806 ha) comprising LAMR, ALFL and its environ was mapped. The area mapped within the Park boundary was 43,037 acres (17, 417 ha). Thirty-four map units were developed to describe the landscape. Of all the map units, the most frequently occurring within the entire mapping area was Map Unit 8, Honey Mesquite Shrubland with 825 polygons ranging in size from under 0.01 acres to over 285 acres. The most abundant map unit in terms of area was Map Unit 17, Upland Slopes/Rolling Hills Vegetation Complex at 27,128 acres or about 31% of the total mapped area but 18% of the Park. Normally the standard minimum mapping unit for NPS vegetation mapping projects is defined as 0.5 hectares. However, this definition was used as a guideline and the actual minimum threshold defined by the high resolution of the aerial photography was more in the range of 1/4 acre.
