DescriptionThe wood of lodgepole pines and whitebark pines from a high elevation site in the east central Sierra Nevada of California was analyzed for chemical content to determine whether there were any temporal patterns of chemical distribution in tree rings. Cores were taken from 10 trees of each species and divided into 5-year increments for chemical analysis. Correlation analysis indicated that calcium and magnesium, both of which have divalent cations, were strongly correlated for both species. The elements copper, iron, cobalt, nickel, molybdenum, chromium, tin, and arsenic were all significantly correlated with one another in lodgepole pine but not in whitebark pine. Concentrations of calcium and magnesium decreased over time for both species, while that of boron increased dramatically. None of the other elements showed significant trends. Most elements had higher concentrations in the youngest wood, which probably reflects greater mobility of soluble forms of elements in and adjacent to living vascular tissue. Chemical concentrations in the wood of trees from this study are presumably free of the effects of substantial input from humans. This data set therefore provides valuable information an wood chemistry with which to evaluate disturbed or polluted stands with similar characteristics.
