Abstract: 

Fire is a dominant disturbance in temperate and boreal biomes, and increasing burned area with climate change may fundamentally alter forests. Improved information about how fire-induced changes to forests may feedback to affect subsequent burning at regional scales could inform forest management and climate-mitigation strategies. However, fire is simplistically represented in Earth System Models, and regional statistical fire models often assume sufficient fuels, contributing to uncertainty in future projections. To address this challenge, we developed the Dynamic Temperate and Boreal Fire and Forest-Ecosystem Simulator (DYNAFFOREST). DYNAFFOREST represents the hierarchical structuring of forests, from individual cohorts to continental extents, making it possible to simulate feedbacks between fire and forests at broad scales over decades to centuries. We parameterized DYNAFFOREST for the western United States of America and benchmarked simulations with observations. DYNAFFOREST recreated patterns of forest cover, structure, and downed fuels, and was capable of capturing average 20th-century fire activity.

Methodology

We developed a coupled fire and forest ecosystem model called the Dynamic Temperate and Boreal Fire and Forest ecosystem Simulator (DYNAFFOREST). DYNAFFOREST is broken into two modules: a forest-ecosystem module and a fire module. We constructed DYNAFFOREST with a hierarchical structure where the forest-ecosystem module operates at a 1-km spatial resolution, and the fire module operates at a 12-km resolution. The time step of both modules is annual. We then evaluated how DYNAFFOREST performs relative to a set of observed benchmarks. See Hansen_environmental modeling and software_metadata_SHARE.docx for complete methodology.

Software

DYNAFFOREST (DYNAmic Temperate and Boreal Fire and FORest-EcosySTem Simulator). Software requirements: R statistical environment and language.
