Height, live canopy volume and annual ring widths of cottonwood trees along the Yampa and Green rivers in Dinosaur National Monument and Canyonlands National Park, Colorado and Utah

Published by U.S. Geological Survey | Department of the Interior | Metadata Last Checked: January 27, 2026 | Last Modified: 2024-07-05T00:00:00Z
We measured the percent live canopy and height of randomly-selected cottonwood trees at three sites: Deerlodge Park on the Yampa River (DLP), Island Park on the upper Green (ILP), and Canyonlands National Park on the lower Green (CAN). From these same trees we took increment cores to understand differences in tree growth in each forest over time. This dataset includes four tabular digital files. The file "cottonwood_characteristics_dlp_ilp_can.csv" includes data on location, age, height, live canopy cover, and fire history. The files "dlp.txt", "ilp.txt", and "can.txt" contain annual tree ring width for trees at DLP, ILP and CAN.
