VEGETATION ANALYSIS OF PRAN BURI DEFOLIATION TEST AREA 1
Abstract
The vegetation of the defoliation test site 1 at Pran Buri was described and inventoried so that data would be available for precise evaluation of the effects of defoliant spraying. The site is in a Dry or Semievergreen forest. Vegetation was divided into categories according to physiologic characteristics: dominant species, intermediate species, shrubs and climbers, and ground cover. Of the 164 species found in the area, 46 were dominant, 35 were intermediate, 64 were shrubs and climbers, and 19 were ground cover. All species belong to 117 genera from 52 families. Formation percentage for each category was determined by counting stems of trails in each of the 83 test plots and was determined by counting stems of each species found in a 30-ft strip 530 ft along the trails. The formation percentages were found to be 17 percent for dominant, 75 percent intermediate, and 8 percent for shrubs and climbers. Ground cover was excluded from the stem count, as it would be a virtually impossible task on that scale of test areas and would probably contribute little to the evaluation. The formation percentages according to phenology were found to be 16 percent deciduous, 82 percent evergreen, and 2 percent uncertain.
