Living in the national and ecological borderlands of Southern Arizona, the Rincon Group of the Sierra Club’s Arizona Grand Canyon Chapter is positioned to influence a diverse set of environmental issues in and around the Tucson metropolitan area. The Rincon Group was created in the 1970s and has grown steadily in scope and influence over the years. Today, the Group addresses several fundamental environmental challenges, including the effects of border security on the region’s landscapes, advancement of abundant renewable energy sources, water conservation and smart growth. Many of our initiatives focus on grassroots movements and rely heavily on the passion and dedication of the greater Tucson community and fellow Sierra Club members. Banner photo by Russell Lowes.

Thursday, April 14. National Park Service and Saguaro National Park. Learn about the National Park Service history from the beginning to 2016, the Centennial year! Jeff Walker, Park Guide at Saguaro National Park will dive into the history of the NPS, how it started and the major steps along the way. Then Jeff focuses on Saguaro National Park's past, present and future. He will discuss the Saguaro Cactus Program at the park, which follows the development of the cactus forest over that last 83 years and what to expect in the future. Saguaro National Park's Centennial projects and events will then be presented, followed by a question and answer session.
Thursday, May 12. Groundwater Depletion Impacts Downtown Tucson. Christopher Eastoe, a retired University of Arizona geoscientist, reveals how the growth of Tucson from a Spanish Presidio to an urban area of 1 million has led to a progressive decline in groundwater availability. By the end of the 19th century, a shallow aquifer beneath the Presidio and groundwater discharge into the Santa Cruz riverbed had failed. By the end of the 20th century, supply from the large regional aquifer of the basin was no longer sustainable. Beneath downtown, oxygen and hydrogen isotopes in groundwater can be used to trace the decline of the water table. Perhaps we could learn from El Paso and Ciudad Juarez, which are reacting effectively to an even worse groundwater loss.
Thursday, June 9. Endangered Cacti: Their Status and Outlook. One third of all species of cacti are endangered, many critically. Sierra Club activist Bill Thornton will discuss the scope of the problem and conservation efforts, with emphasis on two federally listed species in the Tucson area. Bill is a second-generation native Arizonan and lifelong cactus hugger, and a member of the Tucson Cactus and Succulent Society’s “Cactus Rescue” team.
