Mark Chisholm Wins 16th Straight Title at New Jersey Tree Climbing Competition

Mark Chisholm, one of the top tree care experts in the country, won his 16th straight title at the New Jersey Arborist’s Chapter of the International Society of Arboriculture’s (ISA) Tree Climbing Competition.


Chisholm competed against 20 participants and finished with an overall score of 192.60. He took first place in the following three events:


* “Secured Footlock” – Chisholm climbed to a height of 15 meters in 14.75 seconds using only two lines and his upper and lower body strength


* “Aerial Rescue” – Chisholm ascended a tree in a simulated rescue attempt of a distressed climber that was perched 35 to 40 feet above the ground


* “Work Climb” – Using  a climbing harness and rope to move up and around the tree to ring a bell and perform a simulated work task at five designated stations, Chisholm scored the most points and reached the stations in the fastest time.


He held his speed climb world record of 13.8 seconds and also took second place in the “belayed climb” event and third place in the “throw line event,” giving him the top overall score. With this win, Chisholm moves onto the ISA’s International Tree Climbing Championship, on July 26 and 27 in St. Louis. The event will be held in conjunction with the Tour des Trees, an annual cycling event to raise funds and awareness for the work of the TREE Fund (Tree Research and Education Endowment Fund).


“I’m thrilled to continue on in the championship series,” said Chisholm. “It’s such a joy to compete and raise awareness for the industry. Trees are one of our most important resources, and I’m glad to do my part on educating the public on how to care for them.”


Chisholm, who works as a professional arborist with family-owned Aspen Tree Expert Company in New Jersey, has been a spokesperson for Stihl Inc. since 2001.
