The meeting site will be at the USDA Forest Service's J. Herbert Stone Nursery in Central Point. Lodging is available in a variety of hotels in Medford. As with the previous five workshops, the intended audience includes pest specialists, arboriculturists and other professionals who have responsibilities for providing training and guidance in hazard tree management, particularly in forested settings. There will be one and a half days of indoor discussions and presentations and one and a half days in the field. Indoor topics include: Roadside Danger Tree Policies and Assessment; Biology and Taxonomy of Wood Decay Fungi; Oak Defects, Decays and Failures; Options For Not Removing Hazard Trees; Effects of Pruning on Douglas-fir; Illusions and Consequences in Tree-Risk Assessment- When Law and Arboriculture Collide; Powerlines, Wildfires and Tree Failures: School Fire Case Study; and Decay From Phellinus pini: Case Studies and Lessons Learned. An evening poster session/social/decay fungus identification workshop/hazard tree photo contest will also be featured. The field portion of the workshop will include visits to sites in the southern Oregon Cascades on the Rogue River-Siskiyou and Winema National Forests, with one stop in the Rogue Valley at the J. Herbert Stone Nursery. We'll see and discuss a number of hazard tree situations and topics including: decline and failure in native oaks, indicators used in the USDA Forest Service Region 6 roadside danger tree program, the danger of laminated root rot in a recreation site, concerns with decline in specimen legacy trees, and hazard potential in heavily-used developed sites in older true fir stands. Please check the workshop website for details: www.fs.fed.us/foresthealth/technology/htwc/index.htm Right now, the web site contains the workshop agenda, lodging and other general information. Registration information will be posted on the site by March 15, and at that time you will be able to register either by VISA or check. Registration will be $225 through April 30th, and will be $255 after that date. Guest field trip tickets will be available at a nominal price. Please note: Due to meeting room and field trip capacity limitations, the workshop will be limited to the first 88 paid registrants. Also- If you would like to bring a poster to present at the evening poster session/social/decay fungus identification workshop, please contact Kristen Chadwick at klchadwick at fs.fed.us, or by phone at (503) 668-1474. I look forward to seeing you all in June!!! ******************************************** Pete Angwin Plant Pathologist N.

There have now been many demonstrations of the effects of endophytes on plants that range from positive (i.e., mutualism) to negative (i.e., parasitism). This project addresses research areas of site resource utilization with select endophytes and growth, yield and quality of forest plantations. Of fundamental interest is the opportunity to research endophyte community assembly rules under ecologically realistic conditions in a range of host plants including species of Populus and Pinus. Qualifications: * MS degree in mycology, ecology, plant pathology, or related field Prior to formal application to the University of Idaho [Moscow, Idaho, USA] please initially email a letter of interest with your curriculum vitae to George Newcombe at georgen at uidaho.edu .

Message-ID: <4B8A815B.6010108@yale.edu> I received this from a colleague and wondered if anyone had an answer to his question: Dear Professor Schmitz, I am writing at the suggestion of Mary Warner, associate dean of the medical school. Mary and I have been working jointly on a diagnostic medical case project. For many years I have owned a farm on the east bank of the Hudson River just south of the Rip Winkle Bridge. On the steep bank that descends from the farm house to the New York Central railroad tracks, there is a small forest of sumac trees, interspersed with other growth. The sumac trees generally grow straight up, at a rate of 6 to 10 feet per year, with one exception. The exception comes out of the ground and grows in circles. See photo 001, attached. If you will look to the left of the chain saw, you will see a twisted length of copper about three-quarter inches wide. The copper is embedded in the root system of the crooked tree, and cannot be removed by vigorous tugging. When Mary and I looked at these photos last week in her office, we speculated that the DNA of the crooked tree may have mutated and is sending atypical signals to the trees cells. We talked briefly about Wilson's disease in humans, which is due to an excess of copper in the bloodstream. Needless to say, neither of us knows anything about crooked sumac trees. Our current schedule calls for me to return to New Haven at 11 a.m. on Wednesday March 10th. If you expect to be on campus that day, I could bring you a length of the crooked tree. I plan to stay over at the Graduate Club that night, and will therefore be available on March 11th as well. Alternatively, you might like to visit the farm, which is about 2 1/2 hours from Harkness Tower. I would love to have your views on what is causing the crooked tree to grow in circles. Please feel free to discuss this subject with your students. If you search Google Earth for 194 Greendale Road, Hudson, NY, 12534, you will access an aerial view of the farm. The crooked tree is on the bank to the east of the farmhouse/barn at the north end of the farm. To the west of the farm house there is a pinot noir vineyard, while the grapes to the South are largely Chardonnay. I look forward to hearing from you.
