Abstract
Chronologies for the nineteenth century (average tree ring widths for each year)
were developed for Pinus flexilis and Pinus ponderosa growing in northeastern Colorado
and southeastern Wyoming. These chronologies were then run through a step-wise
regression analysis against monthly climatological data in three models: temperature alone,
precipitation alone, and the two together. In all cases, the combination model accounted for
a greater amount of the variation in yearly tree-ring width than either climatic variable alone.
Those months which were the most influential fell in the autumn preceding growth
(September, October, and November) and the spring of the growth season (February,
March, April, and May). Two different types of climatological data were used: NCDC
divisional data and NCDC data for individual cities near the research site. It was
determined that the individual climate data centers were more accurate representations of the
climate experienced at the sample site. There was not a substantial difference observed in
growth-controlling factors between species.
