Description: Survival and height growth data were collected after five field growing seasons from ponderosa pine progeny representing 75 provenances of natural stands in the Great Plains and Northern Rockies. Results showed that trees from no other provenance survived significantly better or grew significantly taller than trees from the Black Hills. Trees from southern Colorado, New Mexico, and western Montana showed significantly poorer survival and height growth. High mortality evidently resulted from a combination of intense grass competition and root rot.
