Methods:

Tree cores were mounted, sanded, and measured according to standard dendrochronological procedures (Stokes and Smiley 1968). Ring widths were measured to nearest 0.01 mm using WinDENDRO software (Regent Instruments Inc., Quebec, Canada). All cores were visually crossdated using a master chronology developed from P. ponderosa of the central Front Range.

Multiple tree cores were collected per sample plot (spatial resolution for tree coordinates is plot level).

Tree core data date range: 1833-2013

Foliage samples were collected from branches exposed to full sun in the upper 1/3 of the canopy. Samples were dried (35C for 50 hrs), ground, and extracted to holocellulose (Leavitt and Danzer 1993). Holocellulose samples were combusted in an elemental analyzer (Carlo Erba EA 1110 Series, Thermo Scientific, Waltham, MA) and analyzed by continuous flow mass spectrometry (VG/Fisons SIRA Series II mass spectrometer, Thermo Scientific, Waltham, MA) to determine the 13C isotope composition at the University of Colorado.

Stable isotope abundance of d13C is expressed relative to the Pee Dee Belemnite standard (Farquhar et al. 1989):

d^13 C(‰)=(R_sample/R_standard -1)×1000

where R is the ratio of 13C to 12C of the sample or standard. Precision of analysis was 0.12 ‰ and accuracy was 0.04 ‰.

Foliar nitrogen was measured using a Thermo Finnigan FLASH EA 1112 Series CHN Analyzer at the University of Colorado.

Tree Foliage Data Date Range: 2011-2012
