We describe the development and performance of a dynamical one-dimensional (1D) model of fire spread (LIHTFire, Linear Ignition and Heat Transfer). The model resolves burning rates, heat transfer, and ignition at cm-scales with explicit accounting of heterogeneous fuels and time-varying weather. An empirical convective heating method speeds computation compared to CFD methods. Heating, drying, pyrolysis, ignition, and solid phase combustion of fuel with varying sizes and shapes is represented by a particle model that captures within-particle gradients. The heat transfer, burning behaviors, and...

Through the Missouri Outdoor Connections project, the USDA Forest Service aims to identify organizations that care for the natural resources of Missouri's central and southern regions so they can better work together. This project seeks to answer the question, “Who takes care of Missouri's natural lands and connects people to their benefits?”

User research is a cornerstone of digital technology development. User experience (UX) designers work to tailor new technologies and software to facilitate intuitive and seamless interactions with their products. With consideration for new capacities in data capture, cleaning, and visualization, the STEWMAP team sought to re-evaluate its survey methodology and digital visualization tools. By systematically engaging STEW-MAP users in our evaluation and adaptation of the project, we opened up the deployment of UX methods towards 1) more nuanced co-production of stewardship research, and 2) more ...

In a future sustainable society, everyday products and necessities—food, clothing, medicine, energy, cars, electronic devices, high-rise buildings, and more—can be made from wood or wood-based polymers and chemicals. Recognizing the potential of wood and wood polymers, U.S. Department of Agriculture (USDA) Forest Service scientists are developing innovative technologies to use these renewable materials in products that are essential to our daily living.

The Joint Fire Science Program (JFSP) and the Environmental Security Technology Certification Program (ESTCP) initiated the Fire and Smoke Model Experiment (FASMEE) (https://www.fasmee.net) by funding JFSP Project 15-S-01-01. This nationwide, multiagency effort identifies and collects critical measurements that will be used to advance fire and smoke science and modeling capabilities, allowing managers to 1) increase the use of managed fire, 2) improve firefighting strategies, 3) enhance smoke forecasts, 4) better assess carbon stores and fire-climate interactions and improve our understanding ...

FAQ's on Data for the Hawai'i STEW-MAP.

This guide walks through using the interactive maps for the Hawai'i Stewardship Mapping Project.

Forests are the largest terrestrial carbon sink in the world, absorbing carbon dioxide (CO2) and storing it as carbon (C) in soils and woody plants. In the United States, forests, wood products, and urban trees collectively offset annual CO2 emissions by roughly 10–15 percent.
