SAN FRANCISCO (AP) - Volunteer scientists are scaling old-growth redwoods in the San Francisco Bay Area in a two-day effort to gather data and document the different creatures living in the trees.
The San Francisco Chronicle reports that 300 scientists on Friday began documenting bugs, plants and other living organisms in the trees' canopies.
Humboldt State University professor Stephen Sillett says they will measure the trees from top to bottom in an effort to determine the redwood forest's ability to sequester carbon.
The group will also study how the ancient trees have reacted over time to weather and climate change.
Redwood tree rings go back to the year 328, providing a valuable resource for understanding previous periods of drought, and other climatic changes.
