The scientists from the Forest and Rangeland Ecosystem Science Center capitalize on their diverse
expertise to answer critically important scientific questions shaped by the equally diverse environments
of the western United States. FRESC scientists collaborate with each other and with partners to provide
rigorous, objective, and timely information and guidance for the management and
conservation of biological systems in the West and worldwide.

Lead Poisoning in Birds from Ammunition and Fishing Tackle
Lead is a metabolic poison that can negatively influence biological processes leading to illness and mortality in North American birds. Lead ammunition and fishing...
Sagebrush Bird Community Response to Pinyon-Juniper Removal
Pinyon and juniper woodlands are expanding into sagebrush steppe areas across the intermountain western United States, affecting species that depend on sagebrush. Land...
Floodplain and Confined Valley Forms have Complimentary Roles in Rivers
In montane regions, rivers often alternate between canyon-confined segments and unconfined floodplain segments. Variation in channel confinement influences sediment,...
New Working Group on Ecological Responses of Large Dam Removal
Dam decommissioning is rapidly emerging as a river restoration strategy in the United States, with several major removals recently completed or in progress across the...
Standard Methods Measure a Hidden Form of Calcium in Soil
Calcium is an essential macronutrient for ecosystem function that occurs in various forms in soil. One form is organically-bound crystals of calcium oxalate, which are...
New Study: Mapping Sage-grouse Perception of Disturbance
Anthropogenic and natural disturbance have caused habitat fragmentation and loss, leading to population declines of greater sage-grouse. USGS ecologist Steve Knick is...
is a fire ecologist who leads research to understand how fire and other disturbances affect ecosystems across broad spatial and temporal scales. Doug and his staff study the historical role of disturbances in shaping ecosystem structure, diversity and resiliency; how plant communities change over time; and the role of disturbance in ecosystem management and conservation. To accomplish research across broad landscapes, Doug uses a variety of tools, including field sampling techniques, GIS, and landscape simulation modeling.
Understanding the Role of Fire and Fuels in Ecological Restoration
is important for land managers to track and manipulate fuel loads in order to assess fire risk, control fire behavior, and restore ecosystems. Fuel loads are important drivers of fire behavior, and fire is an important natural process that can also be used as a tool for ecological restoration purposes. The relationships between fire, vegetation dynamics, and fuel loads are critical to the successful management and restoration of many ecosystems.
