National Big Tree Program – Measuring Tree Girth Webinar

by KHarrold 2. June 2014 10:00

Laser Technology and American Forests co-host webinar on Measuring Tree Girth

Inspired by the need to communicate the changes in established techniques, Laser Technology, Inc. (LTI) and American Forests have co-hosted a series of webinars. The second webinar recording is now available for all who wish to learn updated measuring guidelines and how to minimize errors when nominating national big tree contenders. The three part series highlights the changes made to the program in 2013, and is suitable for all skill levels. Three important topics are covered: measuring crown spread, determining circumference and calculating tree height.

The second webinar in the three part series was all about circumference, otherwise known as the girth of a tree. Keynote speaker Don Bertolette, member of the AF Measuring Guidelines Working Group Team, Alaska State Big Tree List Coordinator and President of the Western Native Tree Society, discussed best methods to measure the girth of a tree on a flat surface, a tree on sloping ground and a tree that leans.

Bertolette also explained what to do when measuring a single tree, multiple trees or multiple-stemmed trees. Other speakers covered various considerations and tests of form, such as bark inclusion or pith. Alive with interaction through the chat feature, this webinar was informative and interesting, with a high view turnout.

If you missed the second installment you can watch it now.
