As an investigation by scientists at Duke University and the Cary Institute of Ecosystem Studies shows, the value of long-term studies can't be understated. In it, investigators looking at the impacts of acid rain on the soil acidity of a New Hampshire forest found that everything behaved as expected for about a decade. But after that, the system went haywire.
For more than 50 years, the Hubbard Brook Experimental Forest in the White Mountains of New Hampshire has been one of the most intensely studied landscapes on earth. Gene Likens, Cary Institute President Emeritus, discusses his new book, Hubbard Brook: The Story of a Forest Ecosystem.
We measure key aspects of forest productivity, species composition and nutrient cycling in the mixed-oak forest at Cary. This long-term monitoring allows us to track trends in the forest ecosystem resulting from air pollution and other stresses.
Environmental Monitoring is a long-term program designed to understand how our environment changes over time. Long-term monitoring allows us to evaluate legislation aimed at controlling pollution and climate change.
