Dear Landscape Notes Readers, As part of my UCANR reporting requirements, I must evaluate the impact of my work.

Please fill out this short survey. It will only take a few minutes and is constructed so that you skip parts that don't apply.

I value your input which will be viewed by only me.

The survey is anonymous and your contact information is optional.
Thanks so much.

Caring for Pruning Tools

You are Invited to Attend the 2018 Chiricahua Rendezvous. 

The Chiricahua Rendezvous is a meeting of arborists, naturalists, and biologists to study trees and their adaptations in the Chiricahua Mountains of South East Arizona.  

The Chiricahuas also offer us a laboratory to examine tree adaptations and natural history up close. The high species diversity, unique land-forms, soils, abundance of insects and animals, and sheer beauty of this part of the American Southwest are unlike anything else in the world.

When: October 8-12, 2018

Limit: 40 attendees

Cost: $475 which includes all meals, lodging and seminars

See attached brochure for details and Rendezvous agenda.
