Christmas Tree Research and Extention Conference During August 2007, the University of Copenhagen’s Forest & Landscape Denmark in collaboration with the Danish Christmas Tree Growers’ Association hosted the 8th International Christmas Tree Research & Extension Conference. Nearly 50 professionals who support the Christmas tree industry attended representing eleven countries: Austria, Belgium, Canada, the Czech Republic, Denmark, Finland, Germany, Greece, Latvia, Norway, and the USA. A total of 28 talks and 21 posters embodying a wide array of research and extension topics related to Christmas trees and greenery were presented. Three field excursions were also integrated into the program including a day-long visit to Langesø Fair, an impressive Christmas tree trade show. Although this group has met periodically since 1987, this conference was our first since organizing as the IUFRO Christmas Tree Working Unit 2.02.09. Operating under the auspices of IUFRO has provided more visibility to our efforts. Additionally, we are taking advantage of the opportunity to develop a unit web site and are initiating a unit newsletter to better communicate among ourselves during the time lapse between our biennial conferences. Congratulations are due to our conference hosts for planning and implementing such a successful and flawless event. The idyllic coastal location of Bogense, the informative technical and poster sessions, the wonderful food and drink, the stimulating field excursions, and especially the collegiality among the attendees combined to make for both an educational and memorable conference. We are all looking forward to the 9th International Christmas Tree Research & Extension Conference which will be hosted by our Oregon State University colleagues in Fall 2009.

  • A PLACE to CHERISH and STUDY BACK Mary Mcdonald
    THE MAGAZINE OF THE OREGON STATE UNIVERSITY ALUMNI ASSOCIATION WINTER OREGON 2016 STATER A PLACE TO CHERISH AND STUDY BACK LOOKING LOOKING Mary McDonald >> and the forest on the hill By Ann Kinkley | Photos by Hannah O’Leary Clipboard in hand, binoculars around her neck, OSU master’s candi- date Amy Barry ’09 moves beneath a canopy of older Douglas fir in the McDonald-Dunn Research Forest, the crown jewel of the College of Forestry’s living laboratories. She’s checking snags — old, dead trees — for small birds such as chickadees, studying how different species make use of the ragged, decaying trunks and branches as the forest matures. Generations of students and researchers have studied, and will continue to study, in the 11,250 acres just beyond the northern city limits of Corvallis, exploring everything from new logging techniques to how various recreation activities change as a forest changes. Told that the woman whose generosity allowed the college to buy the first major pieces of the “Mac-Dunn” had no strong connections to the college but, simply out of gratitude and generosity, wanted to make sure its students had a good place to do their research, Barry is amazed. “That’s absolutely incredible,” she says. “It’s crucial for the work we do to have a forest like this that’s not maintained primarily for tim- ber harvest, but for research. And to have it so close — I can leave my office in Peavy Hall and be here in 15 minutes!” 20 << OREGON STATER hy did Mary McDonald, a wealthy widow in California, give money to Oregon Agricultural College to Wpurchase 6,000 acres of forestland, plus a valuable rare book collection and the resources to create a room for them, as well as endowments for scholarships in several departments? The expertise of Oregon State forestry legend George Peavy had plenty to do with it.

One route follows: From the town of North Fork, head west on the Salmon River Road 033 for about 36 miles (58 km). The western trailhead for FS Trail 172 is on the south side of the Salmon River between river miles 201 and 202 (opposite of Colson Creek RNA), just west of the junction with FS Road 123 (Colson Creek Road). From the trailhead, FS Trail 172 heads south, switchbacking up the ridge west of Shell Creek and gaining about 5000 feet (1524 m) in elevation over about three air miles (4.8 km) as it climbs to an area just below the Horse Heaven Lookout. Just southeast of the lookout, FS Trail 172 joins the ridgeline that defines the western boundary of the RNA. Other routes include FS Trail 021 from Crags Campground, approximately a 10 mile hike (16 km), and the eastern trailhead of 172 which leaves from near the junction of the Salmon River Road 033 and Panther Creek Road 055. Minimum Elevation: 4,700 Feet 1,433 Meters Maximum Elevation: 9,316 Feet 2,840 Meters Site Description Dome Lake RNA contains the entire upper portion of the Lake Creek watershed.

  • TREES AS CROPS in ALASKA PROFILE with an EMPHASIS on SPRUCE Revised 2009
    TREES AS CROPS IN ALASKA PROFILE WITH AN EMPHASIS ON SPRUCE Revised 2009 Robert A. Wheeler Thomas R. Jahns Janice I. Chumley PRODUCTION FACTS Growing trees in Alaska can be difficult. This document addresses basic questions regarding growing tree seedlings as an agricultural crop. Whether growing a few seedlings or thousands, many of the basic production questions are the same. From the standpoint of tree seedling production there are three basic regions in Alaska: Southeast, South Central, and the Interior. Producing high quality tree seedlings is 4-H Tree Sale in Soldotna, AK May 2003 achievable in all three regions however care must (photo/Bob Wheeler). be taken to match tree species requirements with local environmental conditions. Through the efforts of the University of Alaska Fairbanks and the Agriculture and Forestry Experiment Station, many tree species have been evaluated over the past 100 years for their performance. Results from these species trials have led to the listing of tree species, growth characteristics, and site requirements found in Table 1. DEMAND Interest in tree production can vary from growing trees for your yard or property to full scale outdoor or greenhouse, bareroot, or container nurseries. Tree planting and tree sales continue to be of considerable interest to the public although there are no large-scale commercial tree nurseries currently operating in Alaska. A state tree nursery was once operated in the Matanuska Valley area, but it has been closed. Reasons for the closure were based upon the high cost of producing seedlings in Alaska versus what it would cost to import them from nurseries outside the state and also, the overall operational difficulties and risks associated with an Alaska nursery program.
