A public engagement webinar series by the Arizona Institutes for Resilience: Solutions for the Environment and Society (AIR)
Over recent weeks Tucsonans watched as a major fire swept across the Santa Catalina Mountains, a rolling inferno that seemed to engulf most of the range. On the evening of June 5th a dry lightning storm sparked the fire that proceeded to roar from Pusch Ridge in the west to Redington Pass in the east, forcing the evacuation of thousands of people who live on the top and along the mountain foothills.
We all have questions regarding what transpired and what the future holds. Why did this fire get so large? What was the role of climate change and drought? How was wildlife impacted, especially desert bighorn sheep? What role did invasive species have in the extent of the fire at lower elevations? This three-part public webinar series by the Arizona Institutes for Resilience brings the expertise of our community to address these questions and more through live interactions to help us better understand the fire on the mountain.

Episode 1: The Event
Wednesday, August 5, 6 pm to 7:30 pm
Moderated by Tom McNamara, Arizona Public Media
The Bighorn Fire has covered over 120,000 acres of the Catalina Mountains, changing the landscape for decades to come. We will explore its genesis and behavior, and how a 1,000-person fire team responded to the blaze in a way that resulted in zero structures or human lives lost. Local researchers, fire professionals, ecologists, meteorologists, and geologists will help us understand the fire within the context of invasive species; previous burns and fire cycles of the Catalinas; and the weather conditions that fueled the fire, particularly through the lens of climate change. Collectively this session will allow us to see the fire in a new way and begin to comprehend the changes afoot.

Episode 2: The Aftermath
Wednesday, August 12, 6 pm to 7:15 pm
Moderated by Tom McNamara, Arizona Public Media
There is no doubt the Bighorn Fire will have an enormous impact on most aspects of the Catalina Mountains. But to what extent? How might it affect the mountain's wildlife, including desert bighorns, and plant life? What can we expect when the rains arrive with so much less vegetation upslope? Our experts will share research and insights into how this and other fires affect sky island species and physical factors in near time, and what we can expect to see in the coming weeks and months.

Episode 3: The Future Catalinas
Wednesday, August 19, 6 pm to 7:15 pm
Moderated by Vanessa Barchfield, Arizona Public Media
Nature—of which humans are a part—is incredibly resilient. How will the ecological processes and species of the Catalinas rebound (or not) from the effects of the Bighorn Fire? What are the projections for restoration? The researchers in this session have been studying long-term effects of fire in the Sky Islands for decades. They will share insights gained from this careful study that allows us to look into the future and find solutions to restore the landscape and mitigate the challenges ahead. Future actions are broad and we will focus on how you can get involved with local organizations in monitoring and restoration efforts.

Research Scientist, University of Arizona School of Natural Resources and the Environment
Jim Malusa got his first backpack on his 16th birthday, and immediately set off into the Catalina Mts. Forty-seven years later, he’s seen a lot of changes. Equipped with a camera, map, several cans of refried beans, and a PhD from the University of Arizona’s Dept. of Ecology and Evolutionary Biology, Malusa has hiked and documented vegetation throughout the Coronado National Forest. The botanical diversity is mind-boggling because the Coronado sits at a four-way intersection, where the Sonoran Desert meets the Chihuahuan, where the tail of the Rocky Mountains becomes the tip of the Sierra Madre. Ten years ago he took a series of photos in the Chiricahua Mountains for a vegetation map. A year later, the mountain burned. Malusa’s been returning every two years to the same locations to document the trajectory of vegetation change, and today he’s going to share some of those photo sequences to give us an idea of the resilience of different vegetation types, from saguaros to pine trees.
Executive Director, Sky Island Alliance
Louise worked with Sky Island Alliance for the past nine years, most recently as Conservation Director. She was the principal architect of a regional climate change adaptation workshop series designed for resource managers to advance understanding of impacts on ecosystems and wildlife. This led directly to critical new work to survey, protect and restore fragile spring ecosystems. In 2015, she conducted sabbatical work in Australia, where she met with natural resource colleagues to share methodologies for assessing vulnerability of biodiversity, water sources, and human communities to climate change, and developing responsive science, policy and adaptation strategies. She is committed to crafting creative solutions to pressing conservation issues and building collaboration among diverse partners. She holds a B.A. in Ecology and Evolutionary Biology, a B.S. in Microbiology, and an M.S. in Geographic Information Systems, all from the University of Arizona. She is currently Vice Chair of the Desert Landscape Conservation Cooperative, and a member of the Community Water Coalition Advisory Committee, the Art and Environment Network Executive Committee and the Wildlife Conservation Society Climate Change Adaptation Fund Advisory Committee.
Director, Desert Laboratory on Tumamoc Hill
Ben's research is broadly focused in desert ecology and botany. He utilizes multiple approaches and time scales to establish baselines to better understand modern biodiversity and connect science to conservation.
Ben received his PhD in 2014 from the University of California, Riverside under the guidance of Dr. Exequiel Ezcurra for his dissertation research, "Historical Biogeography of the Midriff Islands, Gulf of California." From 2014–2015 he was a Visiting Scholar in the lab of Dr. Rodolfo Dirzo at Stanford University focusing on ecological education for indigenous communities.
His work increasingly looks at the incorporation of diverse perspectives and the powerful results made possible via collaboration. In his role as director of the Next Generation Sonoran Desert Researchers (N-Gen) he strives to create opportunities for collaboration across borders and disciplines and a more holistic understanding and appreciation for the Sonoran Desert.
Since October 2016 Ben has been director of the Desert Laboratory on Tumamoc Hill. He also works with Dr. Christopher Scott in the administration of CAZMEX, the Consortium for Arizona-Mexico Arid Environments.
