Old-growth spruce destroyed at research siteBy NED ROZELLJune 11, 2014
“I’m just really disappointed somebody would come in and do something like that,” Yarie said. “It ended all the data collection going on for that site.”
An old-growth white spruce cut down on a long-term forest research plot.
A few of the 50-inch diameter trees had been absorbing carbon dioxide and emitting oxygen since 1813. Forest expert Glenn Juday of the University of Alaska Fairbanks said mid-slope white spruce trees don’t get much older, because fire sweeps through every 200 years or so. Yarie, 65, helped establish the plot on a south-facing hillside when he was 39. He then measured every tree in the 15-meter by 15-meter square, and has gone back to check the growth of the white spruce every five years. Each year, he or forest technicians have fertilized part of the plot to see how the trees responded (not much) to more nitrogen in comparison to a nearby untouched control plot. “That site is now done,” said Jamie Hollingsworth, manager of the Bonanza Creek Experimental Long-Term Ecological Research site for 11 years. “That data point is no longer there.” Hollingsworth said the old-growth white spruce and the time people had put into the research made the plot a valuable one. “Twenty-five years worth of man-hours is a lot of money,” he said. Hollingsworth, who spends much of his time outdoors as he maintains sites for scientists, has seen “wood poachers whittling away” at the state-owned experimental forest, especially since a jump in home heating oil prices in 2007 and 2008. Because managers of the Bonanza Creek Experimental Forest set it up in 1963 for multiple uses, foresters can’t put up gates to prevent people from driving in to the remote site off the Parks Highway. “We can put up signage, but a sign isn’t going to stop someone who doesn’t care,” Hollingsworth said. Yarie also wonders if the loss of the trees is due to the “firewood craze” in Interior Alaska. “You can start tying this all in to population growth,” he said. “When you go from a town of 10,000 to a town of 100,000, there have to be changes.” Those changes might include regulations on wood harvesting similar to bag limits on moose and fish, Yarie said. The big loss that happened in a few moments was what those trees might tell people about the long-term white spruce ecosystems in Interior Alaska. Forestry studies often yield the best information after generations of people work on them, Yarie said.
