Chiricahua Tree Course
Chiricahua Trees Course
October 3-7, 2022
at 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.
SWRS—South Western Research Station
Is a field station of the American Museum of Natural History and provides lodging (dorm style) and meals each day of the course. SWRS is located in Cave Creek Canyon approximately 5 miles from Portal, AZ. It has a spring fed swimming pool, miles of hiking trails and is extremely quiet and retreat-like. The cost of the course per day is less than most annual meeting hotel rates and includes: lodging, program, and meals.
Course sign up is through the American Museum of Natural History. Cost: The course fee is $73/day. Lodging and meals is an additional $72-82/day. Arrive at the SWRS in the morning on Oct 3rd and depart after breakfast on Oct 8th. Instruction begins after lunch on Monday and ends with evening lectures on the 7th.
Early and late arrivals/departure is available for extra cost. For more information about the course email Jim Downer at firstname.lastname@example.org

Expected Knowledge Outcomes
This is field biology course is augmented with seminars that inform the ecological adaptations of trees. Observing trees in nature illustrates their ecological adaptations and dependence on animals, soils and other plants. The incredible Chiricahua sky island ecosystem provides the laboratory to illuminate the lecture topics. Attendees will gain the following:
- New understanding of desert tree ecosystems
- The interconnected roles of birds, fungi and trees
- The effect of landforms, climate, soils and geology on tree growth
- Impact of Fire on tree ecosystems
- How monsoon adapted trees may be used in landscapes
- Intense discussions with scientists in the field leading to personal revelations about tree biology
- Design in nature. Learn how some very unusual plants grow with each other.
- The impact of tree ecosystems on human wellbeing.
