Rod's video tree tours
Welcome to Rod's Tree Tours for the University of Nevada Reno.
These YouTube video tours take you around the trees and Arboretum areas of the University. At the beginning of each tour is a map to help orient you. The trees in these tours are identified by both common and scientific name.
Throughout the tours there are some botanical classification terms and references (e.g., Nevada State Champion) with which you may not be familiar and are defined in the appendices below.
Appendix B: State champion trees
State Champion Trees
There is a list of State Champion Trees for each state in the U.S. (as well as a National list). To be a State Champion Tree, it must be the biggest of each kind in the state. The Nevada Division of Forestry maintains information and a registry through Nevada's Big Tree Program.
Championship status is based on a point system, established nationally. Points are awarded as follows:
- 1 point for each inch of circumference at 4.5 feet above ground;
- 1 point for each foot of height;
- 1/4 point for each foot of average crown spread;
- These three numbers are totaled, and, if the nominated tree has at least 10 points more than the next biggest tree, it is the State
There are two types of State Champions generally recognized:
- Champions are the biggest of their kind in the state
- Co-champions are tied for the biggest of their kind in the state, within 10 points
Almost all tree species in Nevada are introduced; having had less time to grow to a large size, they naturally are not as big as trees native to an area and perhaps several hundred years old. For example, the National Champion American hornbeam growing in New Jersey (where it is a native species) has 235 points, and the largest American hornbeam in the state has 47 points. But, this tree was probably planted in the last 20 years.
To acknowledge the efforts of Nevadans to increase species diversity, the Nevada Division of Forestry (who administers the state list) has created a new category, "Up-and-coming Trees."
