Thirty Years of Think Trees New Mexico

Just over thirty years ago a couple of idealists (Robert Cox & Bryan Suhr), after hearing Al Shigo and others talking about trees and their care at NUTS I, National Urban Tree Symposium in Denver, thought about doing something similar in Albuquerque. Selling the idea to the director of the Bernalillo County Extension offi ce, John Chappell on the need for this program and his agreeing to provide the support to develop the concept of a local conference about urban trees and their care was providence. With no real idea of what needed to be done and without even a mailing list to contact our potential audience, the seed for the ideals behind Think Trees were planted and have grown to what it is today. We, the conference and board are here because of your ongoing support of those ideals that our trees deserve the best possible care that committed professionals should provide.

There’s a tree growing out of this tree!

How can it be?

This photo was taken (credit, Gilbert Armijo, City of Albuquerque DMD) at the Holiday Park/Community Center in Albuquerque. It is known as a “sport,” or “witches broom” and is defined by ISA as the “abnormal development of multiple secondary shoots, forming a broomlike effect”. Sports are caused by a hormone, stimulated by infection, which crosses the wires regulating the number of shoots grown on a single branch. The infection can stem from a number of factors, including fungi, insects, mistletoe, mites, viruses, and bacteria.

So, it’s not actually a tree growing out of another tree. This particular honey locust sport is reported to be dead, and should be removed in the near future. There are rumors, however (for all you fans of the Alien movies), of a young Siberian elm sprouting from a damaged catalpa limb at Valley Park in Albuquerque. Proceed with caution.
