Comprised of 12 sites nationwide, the Fire and Fire Surrogates study (FFS) is a comprehensive interdisciplinary experiment designed to evaluate the economics and ecological consequences of alternative fuel reduction treatments in seasonally dry forests of the United States. The FFS deploys a common experimental design across the 12-site network, with each site consisting of a fully replicated experiment that compares four treatments: an un-manipulated control, prescribed fire, mechanical treatments, and mechanical + fire. Measurements include vegetation (trees, shrubs, grasses, forbs), fuels (forest floor, features of the living vegetation, and dead wood of various sizes), soil properties (chemical and physical properties of the forest floor and mineral soil), wildlife (birds, small mammals, herps), and bark beetles. While the FFS study did have an economics component, these data were not included for several reasons: data were too highly variable, based on market conditions, variability in practices and use of machines, and the extent to which each project was subsidized.
