Looking belowground: Investigations into belowground plant organs in grasslands and around the world

Projects Posted on: October 15, 2019
Belowground plant structures support aboveground regeneration in ecosystems around the world.  More research is needed to document and understand the anatomy, physiology, demography and ecological role of belowground plant organs.  By working with a global network of scientists we aim to provide research, syntheses and protocols on belowground plant traits.

A public engagement protocol: Social science in support of planning efforts

Science Spotlights Posted on: September 10, 2019
A recently released ‘social vulnerability’ protocol provides a detailed manual for applying social science to support forest and river planning efforts (e.g., forest plan revision). Specifically, the protocol is designed to engage the public about the importance of (and tradeoffs among) ecosystem services, as well as those drivers of change influential to such benefits.

Using FIA data to predict forest understory vegetation structure

Science Spotlights Posted on: September 03, 2019
Understanding the structure of understory vegetation in forests is critical for estimating carbon stocks, fuel loading, and assessing wildlife habit. Using nationally collected inventory data shows promise in providing better estimates and assessments in these areas over large geographical regions.

Engelmann spruce seed production: Long-term study on the Fraser Experimental Forest

Projects Posted on: August 26, 2019
In 1968, thirteen permanent research plots were established in Engelmann spruce-subalpine fir forests along an elevational gradient on the Fraser Experimental Forest. Seed traps were installed on these plots and have been sampled annually since 1968.  

Engelmann spruce seed production is influenced by climate

In 1968, thirteen permanent research plots were established in Engelmann spruce-subalpine fir forests along an elevational gradient on the Fraser Experimental Forest. Seed traps were installed on these plots and have been sampled annually since 1968. In 2011, tree cores were sampled to examine the relationship between climate and seed production.

Where the desert meets the river: Investigating southwestern riparian ecosystems

Science Spotlights Posted on: August 23, 2019
Rivers and streams of the American Southwest have been heavily altered by human activity, resulting in significant changes to disturbance regimes. Riparian vegetation in aridland floodplain systems is critically important as foraging, migrating, and breeding habitat to birds and other animal species. To conserve riparian ecosystems and organisms, understanding how plants and animals are affected by disturbance processes and multiple stressors is critical.

Big trees, bark beetles, goshawks, and timber

Science Spotlights Posted on: August 21, 2019
Throughout the Rocky Mountains over the last century, large ponderosa pine trees provided lumber for growing cities and towns, along with fuel and timber for the mining and railroad industries. Most of these forests are now occupied by dense young and mid-aged forests highly susceptible to being killed by bark beetles and burned by wildfires. These conditions have been exacerbated by fire suppression and urban encroachment. As a result, knowledge is needed to inform management actions directed at restoring and conserving ponderosa pine forests. 

Mountain pine beetle in Colorado: A story of changing forests

Science Spotlights Posted on: August 21, 2019
This research presents synthesis of recent research on the effects of mountain pine beetle outbreaks in Colorado’s lodgepole pine forests. The work updates users, scientists, and the public on research finds on how mountain pine beetle has affected a suite of ecosystem services. 

To masticate or not: Useful tips for treating vegetation

Science Spotlights Posted on: August 21, 2019
Recently, several large fires have burned through masticated sites – including in Colorado (Brewer et al. 2013), Washington, and New Mexico. Burning under extreme weather conditions with strong winds, these fires have challenged the benefits of using mastication, even though mastication can provide many positive environmental effects, such as soil moisture retention and cool, moist environments for soil microbes. However, informing managers when, where, and how mastication is applied is based on antidotal evidence. To address, this issue we synthesized information to provide managers with a current state of knowledge on mastication.

Beetle pheromones and maple volatiles reduce spruce beetle attacks on spruce trees

Science Spotlights Posted on: August 21, 2019
The spruce beetle is the most significant mortality agent of spruce in western North America, and management options are limited. In cooperation with FHP partners, a novel combination of a beetle-produced pheromone (MCH) and compounds from a non-host (maple) tree (AKB) were shown to be repellent to spruce beetles. High-release rate MCH-AKB devices that are attached to live spruce can reduce spruce beetle attacks on individual trees and small groups of trees.
