Native Tree Society Projects and Surveys
The Native Tree Society is involved in a variety of projects and surveys of various
scales, scopes, and durations. A "project" involves an
investigations of a particular topic, species, or activity, while
a "survey" is an investigation of a particular site, area, or region. Some are long term ongoing
investigations
in which a particular site may be monitored for years. Others
involve studies of a series of sites in a particular region, or studies
of a particular species. Somemay be completed in a handful of
trips while others may require dozens. Some involve many
people while others are driven by the efforts of a single individual.
In all cases the goal is to complete the project using the highest
scientific standards.
Completed Projects |
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).
ENTS is non-profit organization devoted locating, measuring and
researching exceptional forests and individual trees of eastern North
America. For the past 12
years, ENTS members have documented unique hemlock forests and
have found trees that exceed the known size limits for the species.
ENTS researchers are the foremost experts in locating,
identifying, and documenting old growth hemlock forests. ENTS
members will be 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. Project Files: Tsuga

Great Smoky Mountains National Park
Tuliptree Project: The large tuliptrees (Liriodendron
tulipifera) within the park are being located and measured
in this project. The climbing and modeling of tuliptrees
in the GSMNP is being conducted under a a scientific research
permit assigned to Will Blozan, Jess Riddle, Josh Kelly, and
Robert Leverett. Will Blozan coordinates the activities and the
pace of that project. In April 2011, the tallest native
hardwood in North America, a tuliptree 190.1 feet tall, was
found in Fork Ridge within the park as part of this project.
It is . The tree was climbed and modeled as part of this
project. The location of this grove of tall tuiptrees was
determined through the use of LIDAR imagery of the area.

Trees Database
Project:
The Trees Database is an experimental project under development
by Mitch Galehouse and Steve Galehouse, with utilization by the
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.
|
Liriodendron Height Project: This project is being coordinated
by Dr. Neil Pederson of the
Lamont-Doherty Earth Observatory of Columbia University.
The goal is to create a height map of tuliptree populations based
upon location and latitude based upon the high resolution height
data collected by NTS members. |
American Chestnut Project: The goal of this ongoing project, being headed by
James Parton,
is to locate and document the remnants of the once expansive
American chestnut forest that once populated the United States
prior to a devastating blight in the 1920's to 30's.
It is out goal to cooperate with the
American Chestnut Foundation
and the
American Chestnut Cooperators' Foundation in the pursuit of
this project. BBS:

Chestnut Project |
Dendromorphometry Book Project: Dr. Lee Frelich, Dr. Don
C. Bragg, and Dr. Robert Van Pelt, Will Blozan, Robert Leverett,
and Michael Taylor are writing a book on tree measurement expanding on the techniques
described in our measurement guidelines along with additional
techniques. The book will be entitled "Dendromorphometry - the Art and Science of Measuring Trees in
the Field." It is intended to serve as a credible book
reference for measurement techniques. In the meantime new
articles, essays, and diagrams will be posted in the
Bulletin of the Eastern Native
Tree Society and to the
NTS BBS. http://www.ents-bbs.org/viewtopic.php?f=235&t=3369

White Pine Project:
The goal of the project is to create a height potential map for
eastern white pine (Pinus strobus) across its range
based upon the high resolution height data collected by the NTS.
The project is being coordinated by Dr. Lee Frelich, NTS Vice
President and Director of the center for Forest Ecology at the
University of Minnesota. |
Big Tree Listings Project:
This project is simply the
compilation of various maximum lists for tree species. The
most current max list, listing the maximums of height, girth, and
crown spread for trees measured by NTS members was compiled by
Jess
Riddle.

Liriodendron Project:
The goal of this ongoing project, being headed by Gary Beluzo,
is to document the range of tuliptrees (Liriodendron tulipifera) and collect information on the phenology of the
species. BBS:
Liriodendron Project |
Triangle Height Measurement Method
Project:
Michael Taylor, in conjunction with Robert Leverett, developed this
modeling method for measuring the height of a tree using three
transit stations and 3 remote baselines. It involves the iterative
solution of 3 simultaneous equations. The process requires the
se of a computer program but can achieve accuracies of a centimeter
or less. Tree heights can be measured at distances of up to
one mile away. The derivation of the method is shown here:
http://www.landmarktrees.net/triangle.html and the required
computer programs can be downloaded here:
http://www.landmarktrees.net/software.html from Michael Taylor's
website. Further discussions can be found
here on our
BBS. |
Bruce Kershner Project:
Bruce Kershner
r (April 17, 1950 - February 16, 2007) was an environmentalist,
author, and forest ecologist. Prior to his death he gave
copies of several of his unpublished or limited publication reports
to fellow NTS member Dale Luthringer. We are in the process
editing those documents for publication in our NTS special report
series. Two of the reports on old growth within the Niagara
River Gorge were written by Bruce as a Project of the
Bert Miler Nature
Club with funding from the
Trillium Foundation.
They are cooperating on the publishing effort. Another report
is of old growth forest at the
Landis Arboretum
forwarded by their arborist, Fred Breglia, for inclusion in the
project. A reports to Friends of Marcys Woods on
Marcy's Woods Nature Reserve,
Ontario and one on Hanlon Creek Heritage Maple Grove Forest
Survey Report to
Kortwright
Hills Community Association, Guelph, Ontario were included in
the reports given to us. We are awaiting permission to
reproduce these documents. Participants Include Edward
Frank, Dale Luthringer and Robert Leverett. |
Aesthetics Project:
The
goal of this ongoing project, being headed by Edward Frank, is to examine
what it is about a particular tree, grove, or forest that tells you that
this is a special place? What is it that touches you in some way
on an emotional, spiritual, or aesthetic level? |
Tree Measurement Video Project: The goal of this project
is to develop a series of videos of tree measurement
procedures.
BBS: Tree
Measurement Video Project is being coordinated by
Edward Frank |
Singapore's Tallest: Search For Singapore's
Tallest Tree - To celebrate this years "Forests For People" as
part of the United Nations International Year of Forests; our
team will be searching for the tallest tree left on the mainland
of Singapore. Once we believe we have found the tallest tree our
aim is to measure the official height from the top-most part of
the tree, record the circumference of the trunk base, video the
canopy's condition and collect data
to put together a summary on the health of the tree. Our hope is
this data will help in continued efforts to preserve the long
life of Singapores Champion Trees.

Erie Gorges Survey:
There are a series of narrow gorges and ridgetops along the southern shore of Lake
Erie from northeastern Ohio to western New York. The gorges
cut through the escarpment above the lake shore plain through layers
of glacial till and generally soft underlying shale bedrock.
There are many patches of old growth forest and mature forest that
persist in these gorges due to the steepness of their sides and the
difficulty of logging in these areas. Investigations so far
have included parks in the
Cleveland Metro Parks System including North Chagrin
Reservation, Cuyahoga
Valley National Park, and
Holden Arboretum in
northeastern Ohio, and a series of gorges in Erie County
Pennsylvania. Chief investigators have included Steve Galehouse, Randy Brown, Dan Reed,
and Dale
Luthringer. Other contributers include Edward Frank,
Carl Harting, Mitch Galehouse, and Will Blozan. Robert Jetton of
Camcore
participated in one of the investigations of a disjunct population
of Carolina hemlock in Cuyahoga Valley National Park with Steve
Galehouse. Investigations at Holden Arboretum were conducted
in conjunction with staff members of the Arboretum. The goal
of the project is to investigate forests and trees found within
these gorges and compare the growth characteristics among them.
