Assessing Fuel Loads in Sagebrush Steppe and PJ Woodlands

Great Basin Fact Sheet No. 9: Assessing Fuel Loads in Sagebrush Steppe and PJ Woodlands

By: Stephen C. Bunting and Jeff Rose

Summary:

This fact sheet helps define wildland fuels and review some of the approaches used to assess fuel loads in Great Basin ecosystems. Assessing wildland fuel loading is important for quantifying potential fire hazards, for monitoring the effectiveness of fuel treatments, and for predicting fire behavior, soil heating, fuel consumption, and emissions. The different methods developed to assess fuel loads in sagebrush steppe and juniper woodland vegetation vary in accuracy, and in time and effort required for sampling. Identifying areas of high and low fuel loading helps during the planning and implementation phases of a project.

In Brief:

  • Managers have developed several approaches for assessing fuel loads that vary with landscape scale, required data accuracy and precision, and resources available for data collection.
  • Understanding and quantifying the different components of wildland fuels, such as total fuel, consumable fuel, and time-lag fuels, is the first step for developing valid estimates of fuel loads.
  • Methods vary from those that are rapid and more qualitative to those that are quantitative. They include fire behavior fuel models, photo series, photoload methods, the planar-intersect method, and remote sensing.
  • Approaches vary in accuracy and in time and effort required for sampling. Fire behavior fuel models or photo series guides are effective for rapidly assess­ing fuel loads on multiple sites, but more intensive methods such as the planar intersect method are useful during the personnel-training phase.
