DNA sampling may save sequoias and redwoods
By tracking the genetics of the whole population, scientists might be able to figure out how to keep sequoias and redwoods living far into the future.
Head into the wilds of California and you'll be struck by the grandeur of two of the state's most iconic trees – the coast redwood and the giant sequoia. Both types of tree have grown for hundreds of years, but their future might be in jeopardy because of deforestation and climate change.
That's where scientists are stepping in with an ambitious project that's sampling their DNA. Take Two welcomed one of that project's leaders, Steve Salzberg, a professor of biomedical engineer at Johns Hopkins University.
