Wildfire Fuels Modeling

The yellow fuel areas near and inside the boundaries of this southern California city are problematic given their proximity to natural areas with higher-risk fuels in orange and red. Both NATURAL AREAS and ORNAMENTAL AREAS inside the city constitute an ignition risk to homes.
Some cultivated landscapes, however, can create valuable buffers between natural wildfire-prone area and homes, such as the AVOCODO GROVE, which appears centered, in dark green in THIS FUELS MODEL. The area underneath this grove is far less susceptible to wildfire than similar areas in the city.
The hazard from fuels can also vary widely as a consequence of fuel moisture, creating the need for adaptive models that can be run under a variety of conditions.

Customizing fuel types for urban environments is an important aspect of zeroing in Landfire data on important aspects of wildfire danger to municipal areas, as evidence in this Southern California city

Creating customized wildfire fuels categories
for urban vegetation in Southern California

When assessing the wildland fuels (vegetation) for a southern California city, we evaluated a large area of ornamental planting inside the planning unit that did not fit into any existing fuels category. With our advanced capabilities in fuels modeling, we were able to to classify this vegetation into a custom model. Fire behavior derived from this model showed potentially dangerous areas for the city not previously addressed. But not all urban landscapes are hazardous. In fact, many man-made landscapes can actual provide useful buffers between natural, fire-prone, landscapes and structures, such as wetland areas, golf courses, parks, and as seen above, avocado groves.
