FAIRBANKS -- Another high-tunnel greenhouse has collapsed at the University of Alaska Fairbanks. A tunnel has collapsed at the Fairbanks Experiment Farm during each of the past two winters.
The Fairbanks Daily News-Miner says the most recent collapse occurred in March, when the second tunnel suddenly buckled. The unheated, plastic-covered structures were built in 2007 to test 39 cold-weather apple tree varieties in Alaska's Interior.
UAF horticulture professor Meriam Karlsson says ongoing apple research should be largely unaffected by the loss of the tunnels. She says the project emerged mostly intact with the summer research season approaching.
