| American Forests http://www.americanforests.org/
American Forests is the nation’s oldest nonprofit citizens’ conservation organization. Citizens concerned about the waste and abuse of the nation’s forests founded American Forests in 1875. The organization is proud of its historic roots in the development of America’s conservation movement and proud of the new approaches the organization has developed to help people improve the environment in the 21st Century. American Forests’ Ecosystem Restoration and Maintenance Agenda presents our core values and seeks to build support for our policy goals. These goals focus on assisting communities in planning and implementing tree and forest actions to restore and maintain healthy ecosystems and communities. We also work with community-based forestry partners in both urban and rural areas to help them participate in national forest policy discussions. American Forests seeks to broaden awareness of the interdependence of communities and forests through our policy and communication activities with local partners.

| American Forests' National Register of Big
Trees http://www.americanforests.org/resources/bigtrees/
AMERICAN FORESTS' National Register of Big Trees is the result of this rallying cry. Since 1940, AMERICAN FORESTS has documented the largest known specimens of every native and naturalized tree in the United States. The largest tree of its species in the country is the National Champion. National champion trees capture our imagination for their size and strength, however, there's more to a champion than just its size—they are symbols of all the good work trees do for the quality of the environment and our quality of life.

Haverford College Arboretum http://www.haverford.edu/Arboretum/home.htm
In 1831, a distinguished group of Philadelphia and New York Quakers purchased 198.5 acres which lay in the center of the Welsh Tract, a part of the 40,000 acres of land ceded to the Welsh Quakers by William Penn. Upon this land the group founded Haverford College two years later. William Carvill, an English gardener, was hired in 1834 to convert the farmland into a functioning campus. His design reflected the influence of Sir Humphry Repton, one of England's great landscape architects.
At the turn of the century, a concerned group recognized the need to preserve Haverford’s rich heritage and formed the Campus Club, which functioned for over fifty years under the inspired leadership of Edward Woolman, Class of 1893. In the early 1970’s, John A. Silver, Class of 1925, envisioned an organization that would carry the work of the Campus Club. In 1974, the Campus Arboretum Association was founded with a commitment to continue the tradition of campus beautification at Haverford College.

Ultimate Tree-Ring web
pages, http://web.utk.edu/~grissino/
designed to be the ULTIMATE source for
information on the science of Dendrochronology. I've designed
these pages to be easily understood by people at all levels of
education, from elementary school students to high school
students, from first grade teachers to college professors. You
won't find anything fancy here - I want these pages to be
readable, enjoyable, and (most of all) educational. My goal is
to make available as much information about dendrochronology as
I can possibly find on the Internet, from the basics of
tree-ring dating, to reference and bibliographic information, to
products and supplies, to books, and more!

Gymnosperm Database http://www.botanik.uni-bonn.de/conifers/
The Gymnosperm Database was established as an
online entity in the summer of 1997 and has since grown
steadily, getting its own URL (Conifers.org) in the summer of
1999. Currently the Database provides basic information
(sometimes only a name) for all species and higher-ranked taxa
of the gymnosperms, i.e., conifers, cycads, and their allies.

Botanical Record-Breakers. http://waynesword.palomar.edu/ww0601.htm
The old adage, "records are made to be
broken," certainly applies to plants. Each year gardeners
from throughout the world compete with their largest tomatoes
and squash, largest potatoes and turnips, largest orchids,
tallest sunflowers and dozens of other superlative categories.
Authenticated records of their prized fruits, vegetables and
blossoms appear in the latest editions of the Guinness Book Of
World Records. But of all the botanical records, the most
remarkable come from wild plants growing in their natural
habitats. These "contestants" compete in a vast
natural arena known as the world ecosystem or biosphere.
Although most of these astonishing plants are listed in the
Guinness Book, several have never been rightfully acknowledged.
