Examining dispatching practices for Interagency Hotshot Crews to reduce seasonal travel distance and manage fatigue

Publications Posted on: November 21, 2018
Interagency Hotshot Crews (IHCs) are a crucial firefighting suppression resource in the United States. These crews travel substantial distances each year and work long and arduous assignments that can cause accumulated fatigue. Current dispatching practices for these crews are supposed to send the closest resource while adhering to existing fatigue-management policies.

Modelling the management of forest ecosystems: Importance of wood decomposition

Publications Posted on: May 10, 2018
Scarce and uncertain data on woody debris decomposition rates are available for calibrating forest ecosystem models, owing to the difficulty of their empirical estimations.

Studying interregional wildland fire engine assignments for large fire suppression

Publications Posted on: September 19, 2017
One crucial component of large fire response in the United States (US) is the sharing of wildland firefighting resources between regions: resources from regions experiencing low fire activity supplement resources in regions experiencing high fire activity. An important step towards improving the efficiency of resource sharing and related policies is to develop a better understanding of current assignment patterns.

New approach to predict deforestation risk can help conserve forests

FS News Posted on: May 25, 2017
A new research collaboration has drawn attention to the risks of deforestation, providing conservationists’ with the tools to predict and plan for future forest loss.  

A simulation and optimisation procedure to model daily suppression resource transfers during a fire season in Colorado

Publications Posted on: January 24, 2017
Sharing fire engines and crews between fire suppression dispatch zones may help improve the utilisation of fire suppression resources.

The Rangeland Vegetation Simulator: A user-driven system for quantifying production, succession, disturbance and fuels in non-forest environments

Publications Posted on: December 27, 2016
Rangeland landscapes occupy roughly 662 million acres in the coterminous U.S. (Reeves and Mitchell 2011) and their vegetation responds quickly to climate and management, with high relative growth rates and inter-annual variability. Current national decision support systems in the U.S.

Forest health in a changing world: Effects of globalization and climate change on forest insect and pathogen impacts

Publications Posted on: July 15, 2016
Forests and trees throughout the world are increasingly affected by factors related to global change. Expanding international trade has facilitated invasions of numerous insects and pathogens into new regions. Many of these invasions have caused substantial forest damage, economic impacts and losses of ecosystem goods and services provided by trees.

The RxCADRE study: A new approach to interdisciplinary fire research

Publications Posted on: February 09, 2016
Much like other scientific endeavours, most fire research is conducted either within individual disciplines - fuels, physics, chemistry, ecology, modelling, and so forth - or, at best, across only two or three disciplines. This is primarily because fire scientists have particular areas of expertise and most collaborations are between scientists within that expertise.

Modelling the role of fires in the terrestrial carbon balance by incorporating SPITFIRE into the global vegetation modelORCHIDEE - Part 1: Simulating historical global burned area and fire regimes

Publications Posted on: October 07, 2015
Fire is an important global ecological process that influences the distribution of biomes, with consequences for carbon, water, and energy budgets. Therefore it is impossible to appropriately model the history and future of the terrestrial ecosystems and the climate system without including fire.

Fire Severity (FIRESEV) Mapping Project delivers information for all phases of fire management

Science Spotlights Posted on: October 05, 2015
Land managers often need the total number of acres burned broken down by these severity classes for planning after wildfire. To meet this need, Forest Service scientists and their cooperators developed the Fire Severity (FIRESEV) Mapping project, a comprehensive set of tools and procedures that create, evaluate, and deliver fire severity maps for all phases of fire management.
