Ever Wonder How Trees Grow?

Have you ever wondered how trees grow? The answer might surprise you. In this video, you’ll learn how trees change on a daily basis while growing larger over time. You’ll also get to see how fast a real Douglas-fir tree grew over 2 weeks in the summer. This information is based on research by the U.S. Forest Service Pacific Northwest Research Station. To learn more about the many aspects of tree growth and timing, check out issues 128, 183, and 210 of the Pacific Northwest Research Station’s Science Findings (https://www.fs.fed.us/pnw/publications/scifi.shtml ) or read the original peer-reviewed publication (https://www.fs.usda.gov/treesearch/pubs/54549) on this topic by Kevin Ford, Connie Harrington (https://www.fs.fed.us/research/people/profile.php?alias=charrington), and Brad St. Clair (https://www.fs.fed.us/research/people/profile.php?alias=bstclair).
