8:15 AM -  9:15 AM     General Session - Part 1

Lessons from Trees   Tanya M. Quist, Ph.D., University of Arizona Campus Arboretum

This talk will present stories about special trees found throughout the world which are valued for the heritage they embody. The term “heritage” refers to something that is “inherited” or “passed along from the past into the future." Indeed, studying history can give us insights to guide us toward a better future and, in the case of trees, we have a tangible bridge connecting past and future. They often live longer than us, precede us in time, or persist long after we leave. This experience gives us perspective and encourages us to take the long view.  While a growing body of research points to a practical role for trees in global sustainability initiatives through the tangible ecological benefits they contribute, necessary actions in this regard are often met with barriers. If the benefits of trees are to be leveraged, those working with them must maintain a clear perspective and strong convictions. To this end, in this talk, we will explore examples of trees valued or revered for their cultural and historical significance throughout the world. Each story aims to expand your understanding of their value to individuals and societies past and present and to deepen your conviction to plant and care for them with the future in mind.

Deeply Rooted   Alfonso Chavez, Cultiva & Jacob RoblesCultiva 

Join as we explore the profound relationship between Indigenous communities and the arboreal world. Delve into the cultural, spiritual, and practical significance of trees in various Indigenous traditions, highlighting how our communities view trees, not merely as resources but as sacred beings with intrinsic value and agency. Through a collection of storytelling, ethnographic studies, and visual documentation, this presentation illustrates how trees feature prominently in storytelling, rituals, food systems, and daily practices. This places emphasis on the reciprocal relationships that Indigenous peoples cultivate with their environments, fostering sustainable living and deep ecological awareness.

This presentation will give an inside look into this program and showcase some of these noteworthy trees.

The History of Honeybees and Trees  |  Anne LeSenne, MS, The University of Arizona Cooperative Extension Pinal County

Honeybees in nature prefer to make their homes in the cavities of trees, so there is a long and interesting relationship between the two. While arborists might look at a hollow or column of decay in a tree as a negative thing, many types of wildlife depend on these hollows for their nesting sites. We will discuss how these hollows develop and the different types of wildlife that use them as they grow larger. We’ll also discuss how climbing arborists can keep themselves and their ground crew safe when working around hives in trees.

Saguaro Salvage Success   |  Judy Mielke, Logan Simpson

Saguaros are iconic plants of the Sonoran Desert.

She will highlight the results of ADOT’s research project that evaluated the transplant success of 1,000 saguaros on four different ADOT roadway projects. The presentation will also cover best practices for salvaging saguaros and providing maintenance following transplant.

Mission Garden caretakes and propagates the majority of the Kino Heritage Fruit Trees Project collection. The presentation will offer details and observations about these specific heritage varieties, desert hardiness, and drought tolerance as well as insight about their roles in the cultural traditions of the region. Cultivation and maintenance techniques will be discussed with regards to water efficiency and mitigating the impact of extreme environmental conditions.
