We are so very sorry to hear about the tragic death of Aaron McGarity. We knew him almost 20 years ago, when we trained him and his mom as recreational tree climbers, and then Aaron as someone who expressed his love for trees by helping others access the treetops as a tree climbing facilitator. We will remember him as a kind and warm-hearted man who had the bug for adventure and challenge. Rest in peace, Aaron, with love from Patty and "Treeman"

Today we mourn the passing of Tom Coffin, a truly great man who will be missed enormously by the people who knew and loved him. Tom passed away this morning of a heart attack.

Tom was TCI's very first tree climbing student and helped to build our organization. Among all his other accomplishments and commitments in life -- and there were so many -- he became a tree climbing instructor, certified arborist, and champion for trees.

We are so very sad.

We are very sorry to learn of the passing of Dr. Randy Miller. Randy came to the 2013 Tree Climbing Rendezvous with his tools and microscopes to teach climbers how to collect tardigrades ("water bears") in the canopy and then isolate them in his microscopes in his mobile classroom at Siimpsonwood. He went on to pioneer, with Canopy Meg Lowman, TCI, and Tree Climbing Kansas City, a federally-funded tree climbing program to train dozens of mobility-challenged students how to climb and do research in the treetops. The people he inspired and whose lives he impacted will never forget him.

Yes, we are leaving Facebook, but not tree climbing! We still love teaching entry-level tree workers and recreational climbers. And we’ll be continuing to watch what all of you do in the future with the skills you’ve learned and the treetop adventures you’ll be taking. Stay safe, keep in touch, and thanks for all your support through the years.

"Beloved limes and sycamores are gone. Most of us will be long dead before their replacements reach anything like maturity."

The result of the council’s vicious campaign means most of us will be long dead before their replacements reach maturity

We're big believers in citizen science.

We encourage you to look for ways you can help gather data and insights to better our forests and their ecosystems.

Specifically, citizen science is when the public voluntarily helps conduct scientific research. Citizen scientists may design experiments, collect data, analyze results, and solve problems. In national parks, most citizen scientists collect data with tools provided by project directors. These data h...
