Big Tree Hunter Workshop

Did you know that Arizona has a program honoring Magnificent Trees? The Arizona Department of Forestry and Fire Management sponsors the Arizona Magnificent Tree Program designed to honor the largest trees of their species (Champion Trees); those with cultural significance (Heritage Trees); and those proven to be in place since Arizona Statehood in 1912 (Witness Trees). At Tohono Chul there are several trees that have this designation!

Want to become a big tree hunter and volunteer for our program? This is the workshop for you! Join us for a workshop with LoriAnne Barnett Warren, the Urban Forestry Specialist from the Arizona Department of Forestry and Fire Management. LoriAnne and her team facilitate the Magnificent Tree Program and seek volunteers interested in learning HOW to use forestry tools to measure the height, circumference, and crown width – the three variables required to calculate the tree scores for both the Arizona Magnificent Tree Program and the American Forests National Champion Tree Registry. After a brief overview of the program, we’ll spend time outside learning how to use hypsometers, biltmore sticks, and forestry measuring tape to calculate the tree scores. The workshop results in a tree measurer “certificate.” Afterwards we hope several participants will sign up for our Magnificent Tree Program “Measurement Verification Committee” to help us measure some of the trees needing to be reverified all across Arizona. Masks will be required in keeping with Tohono Chul’s current Covid-19 policies.

This workshop is free with purchase of Admission to Tohono Chul.
