FireBGCv2 is a computer modeling program and platform that mechanistically simulates fire, vegetation, climate, and fuels dynamics across multiple space and time scales.
Fire management will face many complex and novel issues in this coming century, including dealing with decades of fuel accumulation from past fire exclusion policies, protecting the expanding wildland-urban interface, and managing fire in landscapes that are being invaded by exotic plants and diseases -- all in the face of possible warmer and drier climates. Land managers need innovative tools and information to describe the impacts of past and future human activities on ecosystem dynamics so that they can plan for and respond to the burgeoning issues related to land management and conservation. The spatially explicit ecosystem process model FireBGCv2 is a landscape fire and vegetation model C++ computer program that incorporates several types of stand dynamics models into a spatially explicit landscape simulation platform. FireBGCv2 is intended as a research tool but it can be employed in various land management applications providing sufficient expertise exists to parameterize and initialize the model. This report is divided into four parts. The FireBGCv2 simulation modeling platform is currently used to address six main research areas within the arena of climate-disturbance interactions: 1) exploration of climate-wildfire interactions such as shifting fire regimes and fire severity, disturbance thresholds, and disturbance synergies; 2) effects on ecosystem patterns and processes including vegetation composition, wildlife habitat suitability, forest structure, net primary productivity, and landscape resilience/vulnerability; 3) integration of ecosystem modeling with long-term tree-ring, fire scar, and paleoecological records; 4) effects of climate changes and disturbance processes on landscape carbon dynamics, especially in the context of potential regime shifts; 5) threshold shifts or tipping points, at which relatively small perturbations of forcing variables result in large, abrupt, and long-term changes in ecosystem properties; and 6) potential land management strategies to reduce ecological vulnerability to climate and landscape change. The FireBGCv2 simulation modeling design incorporates climate change scenarios drawn from downscaled Global Circulation Models to define potential future conditions, and simulation landscapes are well-distributed across latitudinal and longitudinal gradients in Oregon, Washington, Montana, Wyoming, Arizona, and Colorado.
