Abstract
In an effort to better quantify NPP of Creosotebush in the Five-Points region, it was decided to test the Point-Quarter method against the standard 1-m2 quadrat method that has been in use since 1998. Transects were laid out across the 5 mammal trapping webs as well as across burned and unburned plots of the Mixed Shrub site (MS). Repeat measures of the same bushes are performed seasonally. Whole shrubs of various size classes are collected and sorted and weighed to develop regressions for biomass.
