"The University of Arizona Campus Arboretum: Building a Botanical and Human Community"

Presented by Tanya M. Quist
Director of the University of Arizona Campus Arboretum

The University of Arizona has been responding to the needs of Arizona since 1891. Over its more than 120 year history, UA faculty have pioneered and applied innovative approaches that have solved a wide range of state challenges. In agriculture, the UA has played a significant role in testing and introducing arid-adapted crop and ornamental plants on the campus grounds that now serve as a palette for southwest landscapes that are hot, sunny, dry, alkaline, cold, and salty! As a result of this work, the campus landscape has integrated lessons in desert horticulture that benefit our students, the greater Tucson community, and global audience through our online resources. Today's talk will provide examples of ways the Campus Arboretum continues to build plant communities and engage students and the community in plant sciences through research, education and outreach.

Tanya Quist earned an undergraduate degree in horticulture science and advanced degrees in both horticulture and plant physiology where she studied the physiological and genetic regulation of plant stress response. This background informs her work in instruction as an Associate Professor of Practice in the School of Plant Sciences where she teaches plant propagation, plant biology, plant physiology and introduction to urban horticulture. In her role as Director of the University of Arizona Campus Arboretum, Tanya provides campus leadership encouraging the application of science in landscape practices, engages students in service-learning, and creates opportunities to integrate plant education into campus landscapes and programs. The central theme of her work promotes arid-adapted trees as foundational to all ecosystems, as they support human health and environmental regulation.

If you have been fully vaccinated for Covid-19, you are welcome to come and join us for this excellent presentation (masks will be highly encouraged but not required). When leaving the live in-person meeting, please enjoy excellent refreshments provided by our member volunteers and also, everyone can get a free plant offered to you by the TCSS.

This meeting will also be a Zoom program and will be an important educational and informational event you much see. Also, if using Zoom, be sure to log in to win a $25 gift certificate from TCSS or choose a copy of the new 3rd edition of the Field Guide to Cacti & Other Succulents of Arizona. Plant give aways will take place at the in-person meeting but that portion of the program, because of the recording, will not appear on Zoom.

"Prevalence and Significance of Illegal Trade in the Cactus and Succulent Collector Community:
Evidence from Qualitative and Quantitative Research"
Presented by Jared Margulies
Assistant Professor of Geography at the University of Alabama

While illegal wildlife trade (IWT) represents a serious threat to biodiversity globally, research into the prevalence of illegal plant collection and trade remain scarce. Cacti and succulents are known as heavily threatened by over-collection for often illegal, international ornamental trade. In my talk I will present data and evidence from a recent study published in Conservation Biology drawing on a large survey conducted in 2021 on the succulent hobbyist collector community, as well as my forthcoming book on illicit cactus and succulent trade based on ethnographic research I have conducted within cactus and succulent collector communities since 2017. Aims of this research included understanding collector perspectives on the Convention on the International Trade in Endangered Species of Wild Flora and Fauna (CITES), the threats IWT poses to cactus and succulent conservation, and how the collector community can better support cactus and succulent conservation efforts worldwide to avoid species extinctions.

Jared Margulies is an assistant professor of geography at the University of Alabama. He is a human-environment geographer whose work focuses on the politics of wildlife conservation, trade, and the commodification and management of wildlife. His book, The Cactus Hunters: Desire and Extinction in the Illicit Succulent Trade, will be published by the University of Minnesota Press in
October 2023. He has published in a variety of academic journals including Conservation Biology,                           Mammillaria bertholdii
Environmental Humanities, Political Geography, World Development, The Annals of the American Association of Geographers, Geoforum, Conservation and Society, and the Journal of Political Ecology. He received his PhD in Geography in 2017 from UMBC in Baltimore, MD, which was supported in part by a Fulbright-Nehru Fellowship in India. He received his Master's degree in Biodiversity, Conservation, and Management from the University of Oxford in 2010. From 2017-2019, he was a postdoctoral research fellow in the Department of Politics and International Relations at the University of Sheffield, UK.
