Santa Rita Experimental Range

One-Hundred Years (1903-2003) of Accomplishments and Contributions
A Conference in Tucson, AZ
30 October - 1 November 2003

(pdf version of this announcement and registration form:


This conference will celebrate the accomplishments and forecast the future contributions on the longest continuously operating research area dedicated to the sustainable management of North American rangelands.


The conference begins on Thursday night with a hosted dinner and presentation on the history of the Santa Rita. During Friday morning and early afternoon, invited speakers will review the significance of research findings developed on the Santa Rita and forecast the opportunities and directions for future research accomplishments. Poster presentations of ongoing research on the Santa Rita will be presented during Friday afternoon.

Saturday morning and afternoon will be spent on the Santa Rita, where short, guided excursions will be made to several locations. A lunch BBQ at the Santa Rita Headquarters in Florida Canyon will conclude the conference. Transportation will be provided from the conference Hotel to the Santa Rita headquarters on Saturday morning. All attendees should plan to use that transportation because limited parking space prevents the accommodation of personal vehicles in the headquarters area.
