The protocols provided below for download refer to measurements for cover and density of perennial grasses, shrubs, and cacti, and perennial grass basal diameter on 131 permanent 1x100-ft. belt transects located on the Santa Rita Experimental Range (SRER). The protocols list the sequence of operations necessary to perform the measurements in each vegetation transect and provide background information.
The Ongoing Vegetation Transect Data that have been collected following those protocols include all measures of cover, density, and/or biomass by species made on those transects since they were established during USFS Studies FSRM 1706-09, FSRM 1706-12, FSRM 1706-15, and FSRM 1706-25.
