They are among the largest and oldest living things on Earth. But scientists say the trees are suffering because of the l

19、ack of water. Now the National Park Service is studying how the drought has affected the sequoias and what can be done to help them survive. Researchers are using scientific equipment in the tree canopies to help measure air temperature and humidity levels. They also are studying sequoia seedlings,

20、information from individual trees and images collected by aircraft to measure the seriousness of the danger.
