    Chiricahua Trees Course

    October 3-7, 2022


    The Southwestern Research Station

    Portal Arizona

    Sponsored by the University of Arizona and The University of California in conjunction with the American Museum of Natural History.


    The trees course is an introduction to the ecology, field biology and utilization of desert adapted trees in landscapes.  The goal of the course is to give attendees knowledge about how trees survive in nature and what lessons this teaches for cultivation of trees in urban and suburban landscapes.  For those holding certified arborist credentials we offer 30 CEU’s during this five day course.

    Structure of the course

    The course involves both field observation and classroom teaching.  Each day will includes lectures and field trips to unique habitats within the sky islands of South Easter Arizona.  The course will focus on tree adaptations to diverse environments, landforms, water resources, and relationships of trees to other organisms.  Each evening after dinner will be keynote seminars by one of the faculty including night field trips to see wildlife that utilize trees at night.

    Presentation Description:

    Food forests are an agroforestry practice that provides benefits well beyond food production. For example, they are a type of multistrata agroforestry, which is ranked #28 on Project Drawdown’s list of the 100 top climate solutions. Beginning in January 2020 a small team began planning a new food forest to be established at Arcosanti, a 52-year-old experimental town located in the high desert, approximately 70 miles north of Phoenix, Arizona.

    Arcosanti is an ambitious project envisioned as an experiment in living frugally and with a limited environmental footprint. The food forest project is part of a larger program to revitalize both agriculture and education at Arcosanti. Beginning in the summer of 2020 work parties began preparing a 0.67-acre site, which consisted of a vacant, weedy field and a small stand of paulownia trees. Site preparation has followed a design that includes a network of shallow basins and meandering paths.

    The first plantings of fruit trees and shrubs, many of which were transplanted from the property of one of the team members, occurred in November of 2020. This food forest project has been informed by nearby examples, including a well-developed food forest at a private residence and a 200-tree orchard at a nearby private school, which will also be briefly described in this presentation.

    Although the work on this food forest is still in its early stages it is already attracting considerable attention. The work parties have grown from mostly members of the Arcosanti community to include groups of AmeriCorps and Pacific Discovery volunteers, students from Yavapai College and Northern Arizona University, and others who are not Arcosanti residents. Thousands of visitors come from around the region and the world every year to visit Arcosanti, making it an ideal location to demonstrate and promote the scaling up of food forests.


    Dr. James Allen is a Professor with the School of Forestry at Northern Arizona University, Flagstaff, AZ. He served as its Executive Director from 2007 to 2021. He is a founding member and immediate past chair of the Southwest Agroforestry Action Network. Dr. Allen’s interest in agroforestry and food forests dates to his work as a Peace Corps Volunteer in Swaziland. His involvement in agroforestry in the Southwest began in 2017, when he took a sabbatical and spent part of it investigating current practices in this region.
