The giant trees on the West Coast are awe-inspiring, but surprisingly, they haven't really been studied much over the long term, notes Peter Bowes of BBC News. The reason?
Unlike studies with smaller plants and almost all animals, no individual scientist is able to track a forest giant for its entire lifespan - from germination to death. They live for hundreds of years and play a vital role in the ecosystem long after they have died.
To remedy that situation, James Lutz of the University of Washington and his team – with the help of volunteers – have set up an open-ended project to monitor a 62-acre plot in California's Yosemite National Park that hasn't burned in the past 70 years. First they're going to measure and map the estimated 30,000 trees in the area. Then they plan to return each year to see if any trees have died and try to determine why.
This is in response to a study by Dr. Lutz [PDF] and others that determined that "between the mid-1930s and the 1990s, the density of large-diameter trees in Yosemite National Park declined 24 percent."
