Southwest regional warming likely cause of pinyon pine cone decline, says CU study
Date:2/12/2013

Creeping climate change in the Southwest appears to be having a negative effect on pinyon pine reproduction, a finding with implications for wildlife species sharing the same woodland ecosystems, says a University of Colorado Boulder-led study.

The new study showed that pinyon pine seed cone production declined by an average of about 40 percent at nine study sites in New Mexico and northwestern Oklahoma over the past four decades, said CU-Boulder doctoral student Miranda Redmond, who led the study. The biggest declines in pinyon pine seed cone reproduction were at the higher elevation research sites experiencing more dramatic warming relative to lower elevations, said Redmond of CU's ecology and evolutionary biology department.

"We are finding significant declines in pinyon pine cone production at many of our study sites," said Redmond. "The biggest declines in cone production we measured were in areas with greater increases in temperatures over the past several decades during the March to October growing season."

Temperature and precipitation were recorded at official long-term weather stations located near each of the nine sites. Overall, average temperatures in the study areas have increased by about 2.3 degrees Fahrenheit in the past four decades, she said.

A paper on the subject by Redmond, Assistant Professor Nichole Barger of CU-Boulder and Frank Forcella of the United States Department of Agriculture in Morris, Minn., appeared in a recent issue of the journal Ecosphere, published by the Ecological Society of America. The new study was funded primarily by a National Science Foundation Graduate Research Fellowship to Redmond.

The cones in which the pinyon seeds are produced are initiated two years prior to seed maturity, and research suggests the environmental stimulus for cone initiation is unseasonably low temperatures during the late summer, said Redmond. Between 1969 and 2009, unseasonably
