Where have all the Pinyon Jays gone?

Science Spotlights Posted on: January 27, 2021
We found Pinyon Jays prefer distinct forest conditions within woodlands for specific activities. These conditions are often present in places targeted for active woodland management. This research provides land managers knowledge they can incorporate into woodland prescriptions that meet management objectives for the treatment area while also benefiting the Pinyon Jay.

Is Mastication Right for Your Site? Science-Based Decision Trees for Forest Managers

Documents and Media Posted on: November 24, 2020
This Science You Can Use article describes the potential benefits of mastication as a forest management tool, presented in the form of a set of decision trees that can guide land managers in choosing the right treatment option for a particular site and management objective.

Where’s the Biomass? A New Approach for Quantifying Biomass and Carbon in the Western United States

Documents and Media Posted on: October 13, 2020
A brand-new Carbon Monitoring System (CMS) developed by RMRS researchers promises to be a valuable resource to support the U.S. Forest Service’s Shared Stewardship Initiative’s goals and policy makers calculating carbon budgets. Document Type: Other Documents

Forest gaps and western white pine regeneration

Events Posted on: October 06, 2020
In this webinar, RMRS research forester Terrie Jain joined Jason Jerman (Coeur d’Alene River Ranger District), James Pass (Three Rivers Ranger District), and Shelagh Fox (R-1 Regional Silviculturist) to discuss forest openings and seedling growth in western white pine restoration.

An Economic Feasibility Study for Forest Industry in Challis, Idaho

Projects Posted on: September 17, 2020
This study is evaluating the potential future wood supply from timber harvest, fuel reduction treatments, and forest restoration on the Salmon-Challis National Forest, and the economics associated with different types of forest industry enterprises that would use these materials, including a sawmill and a variety of other manufacturing and bioenergy options.  

Forest openings and seedling growth in western white pine restoration

Science Spotlights Posted on: September 02, 2020
Imagine you are a western white pine and western larch seedling growing in a forest opening. Your ability to grow into a mature tree depends on the visible sky above you in the opening and the light it provides. Seedlings of other species around you are also racing to grow upward and fill the same canopy space that you are striving to occupy. Your ability to maintain growth and outcompete the other seedlings is critical to your long-term survival.

Headed uphill? Aridity limits lower treelines in much of the western U.S.

Science Spotlights Posted on: August 25, 2020
Many forests in dry mountain regions have a lower elevational treeline that constitutes the dry edge of the forest belt.  Lower treelines currently at their climate limit are expected to be more sensitive to changing climate. Lower treelines constrained by non-climatic factors are less likely to respond directly to climate change but may be sensitive to other global change agents. Understanding the controls on the position of lower treeline can help managers anticipate forest shifts in response to climate change and prioritize vegetation treatments.

Increasing use of prescribed fire: Barriers and opportunities

Science Spotlights Posted on: August 20, 2020
Prescribed fire is an important tool for increasing the resilience of fire-dependent ecosystems and for reducing overall wildfire risk, but it is not being applied at the necessary or desired levels. We investigated barriers and strategies for facilitating prescribed fire application on USFS and BLM lands across the western United States.

Habitat suitability models for white-headed woodpecker in recently burned forest

Science Spotlights Posted on: August 11, 2020
Salvage logging in burned forests can negatively affect habitat for white-headed woodpeckers (Dryobates albolarvatus), a species of conservation concern. To quantify and map suitable woodpecker habitat after wildfires, we developed habitat suitability index (HSI) models to inform forest management activities.

Watering the Forests for the Trees: Water Yield and Changes in Forest Cover

Documents and Media Posted on: August 07, 2020
Forest cover loss may decrease water yield, particularly following nonstand-replacing disturbance in semi-arid western forests. This contradicts the long-held expectation that water yield increases when tree cover is reduced. Document Type: Other Documents
