Between the Lines: Tree Rings Hold Clues About a River’s Past

FS News Posted on: January 10, 2018
Hydrologists are looking centuries into the past to better understand an increasingly uncertain water future.

World’s oldest tree species resistant to mountain pine beetle

FS News Posted on: October 17, 2016
Scientists have discovered that Great Basin bristlecone pine, which has the longest lifespan of any non-clonal organism worldwide, is highly resistance to mountain pine beetle.

Forest Service science bolsters sagebrush and sage-grouse conservation

Media Gallery Posted on: September 16, 2016
Sagebrush ecosystems are among the largest and most threatened ecosystems in North America. Greater sage-grouse has served as the bellwether for species conservation in these ecosystems and has been considered for listing under the Endangered Species Act several times. The 2016 Conservation and restoration of sagebrush ecosystems and sage-grouse: An assessment of USDA Forest Service Science assessment will help meet continuing widespread concerns and calls for science-based conservation to mitigate threats to sagebrush ecosystems, conserve populations of sage-grouse and other sagebrush-obligate species, and restore sagebrush ecosystems throughout the western United States. 

Forest Service science bolsters sagebrush and sage-grouse conservation

Science Spotlights Posted on: August 19, 2016
USDA Forest Service (FS) has been a leader for several decades in developing science and applications to support conservation and restoration of sagebrush ecosystems and sage-grouse populations. This spotlight describes an assessment that explains how and why understanding and supporting FS science is crucial for future management of sagebrush ecosystems.

Dendrochronology of Utah Juniper (Juniperus osteosperma (Torr.) Little)

Publications Posted on: March 23, 2016
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.

A new look at the race for survival: Cheatgrass biocontrol with “black fingers of death”

Science Spotlights Posted on: September 09, 2015
Cheatgrass is one of the most destructive plant invaders in the West with significant economic and ecological impacts on rangelands and agricultural lands. The seed pathogen "black fingers of death" is a promising tool under consideration for biocontrol of cheatgrass. Understanding the effects of slow-growing versus fast-growing pathogen strains may be the key to successfully slow down or stop cheatgrass seed germination.

The effect of planting depth on emergence of 20 native forbs

Projects Posted on: January 22, 2015
This project studies the seedbed ecology requirements of native forbs, particularly the appropriate seeding depth in loam textured soils.

Field testing provisional seed zones for basin wildrye

Projects Posted on: January 22, 2015
In the effort to use genetically appropriate plant materials for restoration projects, provisional seed zones were developed as one method of pairing seed sources to restoration sites. 

Forest inventory and analysis tree-ring data archive and analysis

Projects Posted on: January 22, 2015
The Interior West Forest Inventory and Analysis (FIA) Program collects increment cores as part of regular monitoring. Ring-widths from these increment cores are being digitized and assembled into data products for biogeographical or climatological analyses. 

A 576-year Weber River streamflow reconstruction from tree rings for water resource risk assessment in the Wasatch Front, Utah

Publications Posted on: September 12, 2014
We present a 576-year tree-ring-based reconstruction of streamflow for northern Utah's Weber River that exhibits considerable interannual and decadal-scale variability. While the 20th Century instrumental period includes several extreme individual dry years, it was the century with the fewest such years of the entire reconstruction.
