NTS SP #1a
Tree Measuring Guideline of the Eastern Native Tree Society -Revised by Will Blozan 

Will Blozan writes:   The most significant difference between ENTS measured trees and those measured via conventional forestry methods is a much higher standard of accuracy. In fact, the "ENTS method" of laser-based tree height measurements is so accurate that it is being employed in height growth monitoring projects by several universities and premier forest ecologists. Perhaps the most important value of the ENTS method is that it is repeatable, a basic premise of any scientific project. Users of the method, with a few minutes of training, can produce measured results within 1% or less of a seasoned ENTS researcher. Seasoned ENTS researchers can measure a tree from the ground to within inches of a direct tape drop. This process takes but a few minutes for most trees.

Middleton Live Oak/Sag Branch Tuliptree Project: The goal of the project was to accurately measure the wood volume of the Middleton Live Oak in Middleton Place, South Carolina and the Sag Branch Tuliptree in Great Smoky Mountain National Park. The project is completed and a final report is awaiting an additional review of the data collected. A preliminary summary can be found here: Middleton Live oak/Sag Branch Tuliptree Summary  Partticipants included among others Will Blozan, Robert Van Pelt, Randy Cyr, and Ed Coyle.  Final Report not yet completed.  Preliminary Report

NTS SP #12
 Tsuga Search Project: The goal of the project was to locate, document and preserve exceptional specimens of eastern hemlock within Great Smoky Mountains National Park.  The NPS statement reads: The primary partner for this project is The Eastern Native Tree Society (ENTS). Will Blozan and his team were the primary researchers in surveying, identifying, measuring, and documenting exceptionally large eastern hemlocks in the park. This information will assist park management in targeting important resources at risk and prioritizing areas that require immediate systemic treatment.  The Project was under the direction of Will Blozan.  Final Report not Available.  Project Files: Tsuga Search

NTS SP #13
Old Growth Forest Survey of Eastern Niagara Peninsula
Second Phase/ Final Report
  a Project of Bert Miller Nature Club and
the Ontario Trillium Foundation by Bruce Kershner

When the Old Growth Forest Survey of Eastern Niagara Peninsula began, discoveries of  Old growth Forest sites was fully expected. After two years of extensive surveying, the findings have gone far beyond the goals.  A total of 55 Old growth Forest sites were discovered, totaling 839 acres. These are distributed over 11 cities and towns within Niagara Regional Municipality, from the Niagara River west to as far as Grimsby. The largest is 210 acres (Navy Island), and 5 others are 40 acres or larger. One site, the Niagara Gorge, is filled with, or lined with, 8 different Old growth Forests totaling 195 acres (Ontario side only).

Study to Investigate and Map Old Growth Cedars of Niagara Glen/Whirlpool Area, a Joint Project of Bert Miller Nature Club and Niagara Parks Commission, Report to Niagara Parks Commission, March. 2005, Report Prepared by Bruce Kershner, Co-Investigator.

The goal of this project is to assess the extent of the population, and map the location of, the Eastern White Cedars that grow in the Niagara Glen/Whirlpool area, as well as to get an idea of their age, physical size, and other notable features. This is the first formal, funded study of old-growth cedars of the Niagara Gorge (Canada or U.S.), to the best of this investigator's knowledge. In particular, it is the first time that increment bore samples have been obtained to accurately measure ages of old growth cedars anywhere in Niagara Gorge.

The Last on Earth:  Marcy Woods -Ontario's Endangered Treasure:  Scientific Report Prepared for Friends of Marcy Woods, October, 2005 by Bruce Kershner

Marcy Woods, the last known Old Growth Black Maple forest on Earth, is a globally-significant natural heritage site. Its need for protection is made even more compelling by the fact that it is also the refuge for the greatest concentration of rare and threatened plant and animal species in the Province of Ontario. This biodiversity record even surpasses the famed Point Pelee National Park, located at the opposite end of Lake Erie.

Hanlon Creek Heritage Maple Grove Forest Survey Report, Report to Kortwright Hills Community Association, Guelph, Ontario, April, 2006,
Report No. 1 Prepared by Bruce Kershner, Terrestrial Ecologist.

The woodland site referred to in this report as the Hanlon Creek Heritage Maple Grove in Guelph, Ontario, is one of the sites documented as part of the ecological field work conducted during winter 2006 for the Kortwright Hills Community Association.  The Association arranged for the author of this study, a terrestrial and forest ecologist and old-growth forest authority, to survey and analyze the woodlands of a 670-acre area which the City of Guelph plans to develop into the Hanlon Creek Business Park.
