Improved loblolly pines better for the environment, study finds

Apr 17, 2012

(Phys.org) -- More than 50 years of genetics work to increase loblolly pine production in the Southeast has improved the trees' ability to act as carbon sinks that mitigate climate change, according to a new study by North Carolina State University researchers.

"We've been working to create trees that grow faster and produce more wood, and what this research shows is that at the same time we're enhancing environmental quality by scrubbing as much carbon out of the atmosphere as we possibly can," says Dr. John King, an NC State forest ecologist and co-author of a paper published this month in the journal .

The study estimated a 17 percent increase in stem-wood production and a 13 percent increase in in improved loblolly pines planted throughout the Southeast between 1968 and 2007. Three generations of enhanced seedlings were released over that 40-year period.

Pine plantations cover about 15 percent of forested land in the South. Each year, almost a billion loblolly pine seedlings are planted, typically taking 25 years to reach maturity.

"We're reaping the benefits today of work our predecessors did, and our work will affect our children and grandchildren," says co-author Dr. Steve McKeand, NC State forestry professor and director of the Cooperative Tree Improvement Program, a public/private partnership founded in 1956.

The study marks one of the first attempts to quantify the effects of improved tree genetics on across a large landscape, McKeand and King say.
