They're responsible for the deaths of 40 giant sequoia trees, and counting, at Sequoia and Kings Canyon National Parks. While the bark beetle and the giant sequoias previously coexisted successfully, climate change is transforming their relationship to one with significant consequences.
In all, there are an estimated 75,000 giant sequoia trees in the world, with about 25,000 found in Sequoia and Kings Canyon, according to Christy Brigham, chief of resources management and science at Sequoia and Kings Canyon National Parks.
'The beetles finished them off.' The two-day climb was the culmination of seven years' worth of research and the beginning of a larger project across the Sierra Nevada to study ways to save the shrinking population of naturally occurring giant sequoias.
