When tree rings go global: Challenges and opportunities for retro- and prospective insight

Publications Posted on: December 04, 2018
The demand for large-scale and long-term information on tree growth is increasing rapidly as environmental change research strives to quantify and forecast the impacts of continued warming on forest ecosystems. This demand, combined with the now quasi-global availability of tree-ring observations, has inspired researchers to compile large tree-ring networks to address continental or even global-scale research questions.

Forest productivity varies with soil moisture more than temperature in a small montane watershed

Publications Posted on: October 04, 2018
Mountainous terrain creates variability in microclimate, including nocturnal cold air drainage and resultant temperature inversions. Driven by the elevational temperature gradient, vapor pressure deficit (VPD) also varies with elevation. Soil depth and moisture availability often increase from ridgetop to valley bottom. These variations complicate predictions of forest productivity and other biological responses.

Competition amplifies drought stress in forests across broad climatic and compositional gradients

Publications Posted on: July 18, 2017
Forests around the world are experiencing increasingly severe droughts and elevated competitive intensity due to increased tree density. However, the influence of interactions between drought and competition on forest growth remains poorly understood.

Coram Experimental Forest

Experimental Forests and Ranges Posted on: September 08, 2015
Coram Experimental Forest lies within the Flathead National Forest in the Northern Rocky Mountains of Montana. Spanning 7,500 acres (3,020 hectares), Coram Experimental Forest was established in 1933 for researchers to study western larch regeneration and management. Today, the research conducted and the extensive datasets collected at Coram continue to be critical for western larch management.

Distribution of permanent plots to evaluate silvicultural treatments in the Inland Empire

Publications Posted on: April 19, 2013
To assess the adequacy of a permanent-plot data base for estimating growth and yield, one first needs to know how the plots in the data base are distributed in relation to the population they are presumed to represent. The distribution of permanent plots to study forest growth in the Inland Empire (northeastern Washington, northern Idaho, and western Montana) is displayed using a method that relates the permanent plots to the land base.

Maintaining adequate nutrient supply - Principles, decision-support tools, and best management practices [Chapter 6]

Publications Posted on: April 04, 2011
Maintaining adequate nutrient supply to maintain or enhance tree vigor and forest growth requires conservation of topsoil and soil organic matter. Sometimes nutrient amendments are also required to supplement inherent nutrient-pool limitations or replenish nutrients removed in harvested material.
