Dave Bertelsen’s  Flowering Chart

Since 1984, Dave hiked Finger Rock Trail, elevation gain of 4258 and five miles long, about 1400 times over 29 years. He created this chart which is based on 147,844 observations of flowering taxa. The flora of the Finger Rock Canyon drainage includes 604 taxa; the chart includes 581 taxa in 77 families that have been seen flowering. He is working closely with Drs. Michael and Theresa Crimmins, a climatologist and ecologist respectively at the University of Arizona to analyze the data. Ten papers have been published to date, including collaborations with researchers at the University of Maryland, University of Michigan, and University of California, Santa Barbara.
