Growth and survival before and after a mountain pine beetle outbreak in a ponderosa pine genetic trial

This data package contains data used for the publication "An insect outbreak shifts the direction of selection from fast to slow growth rates in the long-lived conifer Pinus ponderosa" (de la Mata et al. 2017). The study includes measurements from 204 half-sibling families planted in a common garden experiment planted in 1974 and last measured in 2013. The study site is located at the University of Montana's Lubrecht Experimental Forest in Montana, USA as part of the Inland Empire Tree Improvement Cooperative Program. Data are available for family rankings of ponderosa pine survival before and after a mountain pine beetle outbreak and mean family diameter and height at ages 2, 4, 11, 16, 21, and 27.
These data were collected as part of a long-term genetic trial to monitor half-sibling ponderosa pine family growth performance. A mountain pine beetle outbreak affected the study beginning in 2005 and ultimately killed 35% of the trees in the trial. Additional data collection was made in 2013 to determine if there were differences in survival among families and the phenotypic and genotypic relationships between tree growth and survival.
