Monthly Livestock Use by Pasture Since 1908

The database 'Stocking Rate History' available below for download reports the record of cattle use since 1908 across the Santa Rita Experimental Range (SRER).
The file includes 36 separate worksheets; 34 of those are for individual pastures, and the other 2 are summary reports for cattle use across the entire SRER and the change in the size of pastures throughout the length of the record. Notes and layouts about the content of this spreadsheet are available as separated Word (*.docx) files.

Records for 1908-1973 were compiled by S.C. Martin and stored in large-format binders in the Santa Rita paper archive at the Campus Agricultural Center. Records for 1973-2006 are annual grazing plans found in the archive. Records since 2006 are from monthly reports submitted by cooperating rancher Andrew McGibbon.
