This page provides access to the new Santa Rita Experimental Range (SRER) digital archive, the longest record of data available in the Southwest for long-term measurements of climate, vegetation change, livestock use, experimental land use treatments, and repeat photography.
Currently, the digital archive is divided into 13 main sections, listed below. Data users are requested to acknowledge their use of the database in publications, research proposals, websites, and other outlets by following the Instructions for Use, Citations, and Acknowledgement.
The following Update Log records the history of revisions made to the SRER digital archive.
