Pool Table Pines (PTP) CO557 Additional Site Information Daniel E. Ryerson, Thomas W. Swetnam, Ann M. Lynch Detrend method: Smoothing spline Series were standardized with a smoothing spline with a 50 year frequency, response at a wavelength of 150 years. Purpose of Collection: Ecology - insect outbreaks These cores were collected in the Rio Grande National Forest. They were used as a nonhost control chronology for a reconstruction of western spruce budworm outbreaks. Cores are archived and available at the Laboratory of Tree-Ring Research, The University of Arizona, Tucson, AZ. Reference: Ryerson, D.E. 1999.
