“…While Douglas-fir's total width sensitivity to June precipitation in central Idaho and southwestern Montana corroborates previous total width studies from western Wyoming [Graumlich et al, 2003], northern Montana [Pederson et al, 2006], and northern Idaho [Littell et al, 2008], important new insights have been gained from differentiating earlywood and latewood and build on Watson and Luckman's [2002] study in the southern Canadian Rockies. Biondi [2000] suggested that Douglas-fir climate-tree growth relationships might be temporally unstable in central Idaho based on a total width mixed May precipitation and July temperature response from a nearby site.…”

“…Franco) tree ring records (International Tree Ring Databank, http://www.ncdc.noaa.gov/data-access/paleoclimatology-data/datasets/tree-ring). In the greater northern Rocky Mountain region, Douglas-fir total widths have provided estimates of summer Palmer Drought Severity Index [Cook et al, 2004], mean water deficit [Pederson et al, 2006], annual precipitation [Gray et al, 2007], and water-year streamflow [Graumlich et al, 2003;Wise, 2010]. These reconstructions suggest that persistent drought has been an important feature of regional climate variability over the last five to eight centuries, but that the twentieth century appears somewhat anomalous as a wet period relative to the past [Gray and McCabe, 2010].…”

Capturing season‐specific precipitation signals in the northern Rocky Mountains, USA, using earlywood and latewood tree rings

Douglas-fir (Pseudotsuga menziesii Mirb. Franco) total width, earlywood, and latewood tree ring chronologies were developed from six lower forest border sites in the northern Rocky Mountain region of central Idaho and southwestern Montana, USA, to assess the potential for season-specific moisture reconstructions. These long-lived arid-site trees share strong between-tree and between-site coherence, and subannual tree ring chronologies reliably span the past seven centuries. Mapping spatiotemporal patterns in northern Rocky Mountain precipitation highlighted winter-and summer-dominated precipitation regimes that transition along a west to east gradient. When Douglas-fir tree rings were compared with instrumental climate records, season-specific correlations emerged between earlywood and latewood. Total width, earlywood, and latewood shared the most statistically significant monthly correlations with April-June precipitation, whereas variability in adjusted latewood was tuned to June-August precipitation. Principal component analysis indicated that the leading mode of common variance for earlywood and adjusted latewood explained 65% and 55% variance in the chronologies, respectively. Pearson's correlations between earlywood principal component one and the northern Rocky Mountain precipitation field showed that annual (July-June) and spring (April-June) precipitation exhibited the strongest pattern of significance in central Idaho and southwestern Montana valleys and the Snake River Plain. Summer precipitation (June-August) was correlated with adjusted latewood principal component one and was particularly pronounced along and east of the continental divide in southwestern Montana. These results indicate that Douglas-fir earlywood and adjusted latewood tree rings in the northern Rocky Mountains retain season-specific precipitation signals and may be helpful for studying historical precipitation within the winter-summer transition zone.

“…If regional climate becomes warmer and drier, we expect snowpack in the GYE to decrease, spring flows and flood pulses on the Yellowstone River to peak earlier, summer baseflows to decrease, and late summer water temperatures to increase (Stewart and others 2004; Mote and others 2005; Knowles and others 2006). Whereas long periods of low flow have occurred on the Yellowstone River over the past 300 years (Graumlich and others 2003), climate change will superimpose a long-term warming trend on natural flow variability (Milly and others 2008). This would decrease summer baseflow relative to the past century through increased evaporation and decreased snowpack, even if precipitation increases moderately (Stewart and others 2004).…”

As natural resource management agencies and conservation organizations seek guidance on responding to climate change, myriad potential actions and strategies have been proposed for increasing the long-term viability of some attributes of natural systems. Managers need practical tools for selecting among these actions and strategies to develop a tailored management approach for specific targets at a given location. We developed and present one such tool, the participatory Adaptation for Conservation Targets (ACT) framework, which considers the effects of climate change in the development of management actions for particular species, ecosystems and ecological functions. Our framework is based on the premise that effective adaptation of management to climate change can rely on local knowledge of an ecosystem and does not necessarily require detailed projections of climate change or its effects. We illustrate the ACT framework by applying it to an ecological function in the Greater Yellowstone Ecosystem (Montana, Wyoming, and Idaho, USA)—water flows in the upper Yellowstone River. We suggest that the ACT framework is a practical tool for initiating adaptation planning, and for generating and communicating specific management interventions given an increasingly altered, yet uncertain, climate.

Changes in Regional Hydroclimatology and Water Resources on Seasonal to Interannual and Decade‐to‐Century Timescales

Precipitation, runoff, snowpack, and other elements of the hydrologic cycle respond to climate change on many different timescales. Responses are typically regional rather than local and are linked to large‐scale features of the general circulation of the atmosphere. Changes in regional hydroclimatology are important to water resources in most parts of the world, but especially in arid and semiarid regions that are often plagued by chronic shortfalls of water. Instrumental records of precipitation and streamflow indicate that changes on decadal‐and‐longer timescales have been large enough to be of practical importance, and paleoclimatic records suggest that even larger changes have occurred over the past few centuries. Tree‐ring records are perhaps the most useful of the paleoclimatic resources for extracting hydroclimatic estimates with annual resolution. Paleolimnological data has also figured prominently in pointing out possible large changes in regional hydroclimatology prior to the start of the tree‐ring record. In North America, multiple types of proxy records suggest low‐frequency variance in runoff may have been amplified about 500 years ago, with associated multidecadal periods of drought and wetness.
