Data product containing 22-year Nebraska tree heights, survival, and genetic variation for "Ten-Year Performance of Ponderosa Pine Provenances in the Great Plains of North America"

Publication Year: 
Author: Read, Ralph A.

Seeds from 79 natural stands throughout the ponderosa pine range, both east and west of the Continental Divide, were sown and grown in a nursery for three to four years in the 1960's. Some of these seeds were then distributed to three different field plantations in Alliance, Hastings, and Plattsmouth Nebraska. These datasets contain individual tree heights of surviving trees, taken at various frequencies from 1968 to 1987. A very small percentage of trees at the Plattsmouth plantation were also measured in 1989 (19-year tree heights).
