Meetings of the Tucson Chapter

Location for Chapter Meetings

The Tucson chapter holds meetings between September and May each year, with a summer break.  We meet on the second Thursday of each month at 7:00 pm.  We are now having “hybrid” meetings, both  in person and also aired on Zoom.  The live meetings will be in Room S107 of the ENR2 (Environment and Natural Resources 2) building at the University of Arizona, located on 6th street near Park.  If you are not on our mailing list and wish to attend one of our meetings on Zoom, email us at [email protected] to request the Zoom link.  Videos of past meetings can be found on our YouTube channel.

The Sonoran Desert region can be described as the receding hairline of the tropics, culminating in the precipice of the true tropical and temperate-tropical realm of northwestern México in eastern and southern Sonora. Noteworthy and novel botanical (and otherwise) records will be presented.


Robert is a Sonoran Desert rat, born and raised in Tucson AZ. He has been schooled by such mentors as Tom Van Devender and Ana Lilia Reina-Guerrero, Richard Felger, Amadeo Rea, Mark Dimmit, and other Sonoran explorers. He is president of Tucson Herpetological Society, and outreach specialist at the Desert Laboratory on Tumamoc Hill.

Tucson Chapter PICNIC and PLANT RAMBLE! Saturday, September 11 at 11:00 am

Posted on Sep 02, 2021

After a long period of virtual-only meetings, let’s have an outdoor get-together!  Join us on Saturday, September 11, 2021, for a “bring your own everything” picnic and plant ramble at 11:00 am at the Molino Basin Campground and picnic area about 6 miles up on the Catalina Highway in the Coronado National Forest.  We can meet and chat in the relative safety of the outdoors, and after lunch, several members will lead short plant walks in the vicinity. 

In the spirit of COVID, we will provide exactly NOTHING.  You will need to bring your own lunch, beverage, and chair or stool or blanket. Bring a hat, water, sunglasses and sunscreen, and anything else you will need. Depending on the size of the group, we may cluster around a picnic table or two, or we may just gather near the parking lot.  But for those of us who are vaccinated and feel comfortable with such a gathering, we hope to see you there. We are especially looking forward to meeting any new members of our chapter who have not yet been able to attend any events in person! However, please be prepared to practice social distancing and wear a mask.
