Resumen de Where no tree has gone before.
The article cites a report in the October 2012 issue of "Landscape Ecology" magazine on the results of a study by the U.S. Department of Agriculture Forest Service which found that tree occupation in the sub-alpine meadows of Jefferson Park in the central Cascade Range in Oregon has increased from eight percent in 1950 to 35 percent in 2008. According to the study's authors, a warming climate has resulted in a lengthened growing season causing an encroachment of forests on meadowland.
