Drought stress detected in tree rings suggests an impending tipping point for forests on the Navajo Nation
Forests across the southwestern U. S. face escalating challenges from changing climate. The objective of this study, conducted in partnership with the Navajo Forestry Department (NFD), was to assess the impact of climate variability and change on forest health on the Navajo Nation by adding tree-ring sampling to a stratified random subsample of NFD’s Continuous Forest Inventory plot network. Increment cores from 1075 trees at 56 plots were used t…
Arroyo formation impacts on an early dryland agricultural community in Northeastern Utah, USA
Indigenous Fremont farmers in Cub Creek, a part of northeastern Utah's Dinosaur National Monument, occupied the northern ecological margin of maize cultivation in western North America from A.D. 300 to 1300. Agriculture in Cub Creek was a response to multidecadal precipitation variability, but when precipitation stabilized between A.D. 750 and 1050, agricultural conditions improved and populations expanded to form villages along the floodplains o…
Multidecadal Climate Variability and the Florescence of Fremont Societies in Eastern Utah
Fremont societies of the Uinta Basin incorporated domesticates into a foraging lifeway over a 1,000-year period from AD 300 to 1300. Fremont research provides a unique opportunity to critically examine the social and ecological processes behind the adoption and abandonment of domesticates by hunter-gatherers. We develop and integrate a 2,115-year precipitation reconstruction with a Bayesian chronological model for the growth of Fremont societies …
Climatic Drivers of Ponderosa Pine Growth in Central Idaho
Despite the widespread use of ponderosa pine as an important hydroclimate proxy, we actually understand very little about its climate response in the Northern Rockies. Here, we analyze two new ponderosa pine chronologies to investigate how climate influences annual growth. Despite differences in precipitation amount and timing and large elevation differences (1820 m versus 1060 m), ring width at both sites was strongly driven by water availabilit…
Dendrochronology of Utah Juniper ( Juniperus osteosperma (Torr.) Little)
Utah juniper was a foundational species for the discipline of dendrochronology, having been used in the early 20th Century investigations of Mesa Verde, but has been largely ignored by dendrochronologists since. Here we present dendrochronological investigations of Utah juniper core and cross-sectional samples from four sites in northern Utah. We demonstrate that, contrary to the general opinion among many dendrochronologists, Utah juniper exhibi…
Tree-ring reconstruction of the level of Great Salt Lake, USA
Utah’s Great Salt Lake (GSL) is a closed-basin remnant of the larger Pleistocene-age Lake Bonneville. The modern instrumental record of the GSL-level (i.e. elevation) change is strongly modulated by Pacific Ocean coupled ocean/atmospheric oscillations at low frequency, and therefore reflects the decadal-scale wet/dry cycles that characterize the region. A within-basin network of seven tree-ring chronologies was developed to reconstruct the GSL wa…
Using fire regimes to delineate zones in a high-resolution lake sediment record from the western United States
Paleoenvironmental reconstructions are important for understanding the influence of long-term climate variability on ecosystems and landscape disturbance dynamics. In this paper we explore the linkages among past climate, vegetation, and fire regimes using a high-resolution pollen and charcoal reconstruction from Morris Pond located on the Markagunt Plateau in southwestern Utah, USA. A regime shift detection algorithm was applied to background ch…
