The Eastern Native Tree Society (ENTS) is a cyberspace interest group devoted to the documentation and celebration of trees and forests of the eastern North America and around the world, through art, poetry, music, mythology, science, medicine, wood crafts, and collecting research data for a variety of purposes. ENTS is the premiere tree measuring group of the eastern forest. ENTS is a discussion forum for people who view trees and forests not just as a crop to be harvested, but also as something of value in their own right.   Membership is open to anyone with an interest in trees living anywhere in the world.

The Eastern Native Tree Society was originally established to accurately measure and record the tallest trees, historical trees, and ancient forests of Eastern North America. Eastern North America has been graced with forests of fantastic beauty and diversity. These forests have been heavily impacted by development, disease and human utilization. This unfortunate history has diverted our attention from the remarkably huge and ancient forests which have survived this catastrophe. Even today we are finding the largest and oldest trees ever recorded for some native species. The tallest white pine ever accurately recorded was recently documented in the Cataloochee district of Great Smoky Mountains National Park. The oldest trees ever recorded in eastern North America have been recently discovered along the Black River, in eastern North Carolina.  ENTS will store data on accurately measured trees for historical documentation purposes, scientific research, provide an archive for information on specific trees and stands of trees,  and to resolve big tree disputes. 

 In July of 2011 the overall organization changed its' name to the Native Tree Society to reflect a broader geographic membership and was restructured to reflect this organizational change.  The organization has two formal chapters:  the Western Native Tree Society for those people in western North America, and the Eastern Native Tree Society covering the eastern United States and Canada.  Members from elsewhere in the world are considered to be members at large to the NTS.  Official membership in NTS is obtained by joining the NTS BBS at  The single BBS Forum is for all all members of the Native Tree Society and any  member may post in any forum regardless of their geographic location. We hope to establish ties with tree interest groups in other countries and to share our passion for trees and to promote the usage of our measurement standards and scientific goals in these areas. 


  • Measurement Discussions

  • Tree Measuring Guidelines of the Eastern Native Tree Society;

  • ENTS publishes a formal Journal - The Bulletin of the Eastern Native Tree Society - two to four times annually;

  • ENTS members provide reports on field trips made to forests found in the United States,  Canada, and from other locations around the world;

    Trees Database  The Trees Database is an experimental project by Steve and Mitch Galehouse, with utilization by the Eastern Native Tree Society in mind. This site allows you to review, search, sort, add, and download information concerning native(and exotic) tree species, including height, girth dimension, geographic location, and site specifics. The intent is to include as many tree species from as many locations as possible to make it possible to compare tree species' size potentials across their native ranges.

  • ENTS conducted the first detailed mapping of the branch and trunk structure and volume measurements for the largest Eastern trees, including -   The Middleton Oak and Sag Branch Tulip,  The Tsuga Search Project documented the largest living Eastern Hemlocks in existence before they fell prey to the invasive Hemlock Woolly Adelgid and died;  The Live Oak Project is documenting the Live Oaks of the southern United States, The American Chestnut Project is documenting the surviving remnants of the once great America Chestnut after the species was devastated by blight in the 1920'2 and 30's; the Aesthetics Project is trying to define what makes trees and forests special, and we are involved in a host of other research projects;

  • On March 14, 2010 the Eastern Native Tree Society and Western Native Tree Society switched from discussion lists on Google Groups to a new discussion list in a Bulletin Board format at:  Posts made since the inception of the BBS on March 14, 2010 will be sorted and archived on the BBS. Click on the link to go to the equivalent section on the new BBS. This website will continue to serve as a front end for the ENTS and WNTS groups. It will continue to serve as a repository of older posts, and will serve as the host site for special projects and features that are not well suited for a BBS format. Please visit the BBS for the latest information and trip reports.
