What Trees Know about Drought

The trees in Utah's forests suck up water like sponges, and leave a record in their growth rings of when there was a lot of water in the region and when there was very little. Researchers are learning to decode the tree ring record and reconstruct what Utah's watersheds have been through over the past millennium. In this episode, we bring you the story of how Utah's water past can help us plan for Utah's water future.
