University of Arkansas Tree Ring Laboratory http://www.uark.edu/misc/dendro/ The Tree-Ring Laboratory (TRL) was established in 1979 and concentrates on the development of exactly-dated annual tree-ring chronologies from ancient forests worldwide. These tree-ring chronologies are based on small non-destructive core samples taken from living trees, and cross-sections cut from dead logs. Tree-ring chronologies provide unique archives of environmental history, and have important applications to climatology, ecology, hydrology, seismology, archaeology, and history.


Center For Hardwood Ecology  http://www.cnr.umn.edu/FR/CFHE  The Center For Hardwood Ecology at the University of Minnesota is an intercollegiate unit with the College of Natural Resources and College of Biological Sciences  The founder of the center, Lee E. Frelich, is the current director.   Margaret B. Davis and Peter B. Reich  are co-founders of the center. The mission of the Center for Hardwood Ecology is "To locate, protect, and study a very rare ecosystem: old-growth hardwood forests in the Midwest and eastern U.S., to use the knowledge gained from old-growth ecosystems to restore second growth forests and forests that have been converted to other uses, and to bridge the gaps between science, conservation, and management in hardwood forests.  The center meets the mission statement through three goals: 1) Fund a comprehensive research program aimed at producing the knowledge we need to save, manage, and perpetuate the remnants of an endangered ecosystem--old growth hardwood forests in the Midwest and eastern U.S., 2) Provide educational opportunities for the best students who are interested in research or management careers in natural resources, 3) Bring the University of MN national and international recognition as a center of excellence in forest ecology. 


Ancient Cross Timbers Project:  The Cross Timbers are the post oak and blackjack oak woodlands that form the western frontier of deciduous forests in Texas, Oklahoma, and southeastern Kansas. Literally thousands of acres of ancient forest survive in the Cross Timbers because these stout oaks were too short and craggy for commercial sawlog production.   Post oak trees up to 400 years old and red cedar trees over 500 years old have been found in these interesting woodlands. Unfortunately, the great antiquity of the uncut Cross Timbers is not widely appreciated and they continue to be destroyed.  This project is dedicated to the location and appreciation of these authentic ancient forest remnants.  http://www.uark.edu/misc/xtimber/ 


Primal Nature   http://www.primalnature.org (absorbs the site http://www.old-growth.org  and the Eastern Old Growth Clearinghouse.) The new site will continue to give news of eastern old-growth forests but will gradually extend its coverage to other types of ecosystems. A project of Yggdrasil of Earth Island Institute, the Eastern Old Growth Clearinghouse was founded in 1996 to further the preservation and restoration of old-growth forests in the eastern United States.

  Persimmonpudding.com  dedicated to growing, education, and use of Diospyros virginiana L., the common, or American persimmon http://www.persimmonpudding.com  Barry Nichols writes:  "I've been cobbling together a native botanical food heritage/history/etc website on our native persimmons (Diospyros virginiana) called http://www.persimmonpudding.com  . I'm a biologist and while I'm interested in native plants, I've been wholly captivated by persimmons since I was a kid. I use the tree heavily in habitat restorations and mitigation efforts. I also use others, but in my experience, restoration plans usually incorporate a lot of trees that would seed themselves quickly, or include robo-trees which will grow quickly, but provide little in the way of complexity. It is often the deep-rooted trees which are overlooked due to the need for careful handling and planting. Another aspect to the site is food heritage. It pains me greatly to hear from folks who tell me about the importance of persimmons and their family's uses, holidays, etc...just to have the end of their account be something akin to, "When Grandma Betty died, the family recipes were lost forever". Pure tragedy. Thus, while I research the history and herbal uses, I am also desperately trying to reach out to families today to get their stories, recipes, etc.

Eastern OLDLIST http://www.ldeo.columbia.edu/~adk/oldlisteast/  
Eastern OLDLIST is a 'franchise' database of OLDLIST, a database of ancient trees and their ages. The purpose of this list is to identify and highlight the maximum ages for different species in eastern North America as documented through tree-ring analysis over the last few decades such that exceptionally old age individuals may be recognized.

Gynosperm Database http://www.conifers.org/ 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.


Ultimate Tree-Ring web pageshttp://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!

Some works by Dr. Alex Shigo:  

Shigo and Trees, Associates LLC
Shigo and Trees, Associates was begun in 1985 by Alex and Marilyn Shigo at their home in New Hampshire. Alex had retired after more than 25 years as Chief Scientist in the US Forest Service, and had many ideas about trees and their care to share. His first book was A New Tree Biology, a totally new vision of trees and their physiology based on his many years of tree dissections, published in 1986. For twenty years of “retirement” he traveled throughout the USA and the world giving demonstrations, making presentations, organizing workshops and educational seminars, talking with individuals, and sharing his passion about trees. In all of his encounters he encouraged people to “Touch Trees TM,” to learn about and understand trees for themselves from the inside and outside, and through the microscope. He loved trees, he loved the people who worked with trees, and strived endlessly to improve the lives of trees through his writing, his presentations, and his work with people.

Tennessee Hemlock Rescue http://www.tnhemlockrescue.org/ This organization is dedicated to the preservation of the Eastern Hemlock, Tsuga canadensis, a tree species threatened by an introduced insect, the Hemlock Wooly Adelgid or "HWA". Throughout the Appalachians, entire forests of this tree have been destroyed and HWA is now well established in Cherokee and Nantahala National Forests where most trees are in severe decline. Many are near death including the giant 300-400 year-old Hemlocks of the Citico and Kilmer-Slickrock Wilderness Areas and Great Smoky Mountain National Park (GSMNP). Although many trees within the park have been treated, the national forest wilderness areas remain almost entirely unprotected. This organization will work to ensure the preservation of at least a small number of intact old-growth Hemlock stands within the wilderness areas of Tennessee and surrounding states as well as other appropriate areas. 
  North American Bear Research http://www.bear.org/  Our focus is to improve the understanding and appreciation of North American Bears, their role in the ecosystem, and their relationship to humans through education, research, and rehabilitation. It is the mission of the North American Bear Center to be a leader in providing understanding and appreciation of black bears, their role in the ecosystem and their relationship to humans. This will be accomplished through a facility that promotes and provides educational facilities, exhibits, multi-media presentations, and when prudent, live animals, particularly those needing clinical rehabilitation.  North American Bear Center, 1926 Hwy 169, Ely, Minnesota 55731 phone: 218-365-7879
The Laboratory of Tree Ring Research http://tree.ltrr.arizona.edu/  The primary mission of the Laboratory of Tree-Ring Research is to apply dendrochronology (the study of tree rings) to improve understanding of natural environmental variability in climatic, hydrologic, geomorphic, and ecological systems and their interactions with human societies.  Located at The University of Arizona in Tucson, Arizona, the LTRR was the first dendrochronology laboratory  anywhere in the world, first established in 1937 by  A.E. Douglass. Today, it serves as one of the premier tree-ring research facilities with nearly 90 personnel investigating nearly all topics in dendrochronology. Current research efforts are directed toward the quantification of tree-ring parameters, the establishment of new tree-ring chronologies throughout the world, the use of tree rings in the study of forest ecosystems, the reconstruction of paleohydrologic and paleoclimatic variables, and the documentation and development of prehistoric chronological controls.

Botanical Record-Breakershttp://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.



GoogleEarth  http://earth.google.com  It is a free download program. It merges 3D rendered terrain mapping with Landsat and NAPP aerial photography to create near photorealistic visualization of anyplace on earth with zooming, panning, rotating, tilting, and fly-bys. I visited Cook Forest, Mohawk, the Porkies, and the Smokies with it. The Grand Canyon works really well with it. In Chicago, turning on "Buildings" enables low res 3D building outlines to help you visualize the downtown area. You can mark locations anywhere and then email them to others as .kml files. It requires a PC made in the last couple of years or so and a reasonably fast internet connection. A pay version adds additional GIS import functionality

Here's a page to outline areas on a Google map or aerial photo and then calculate the area within:
