Buffalo Creek Fire

This project investigates the effects of biosolid application on erosion, plant establishment, biomass production, and species diversity in a burned area. The experiment includes different application rates of biosolids and evaluates the chemical quality of plants and soil, as well as runoff quantity and quality.

  1. Buffalo Creek Fire Investigators CSU - Redente, Barbarick, Miller EPA - Brobst

  2. Background Information • Fire May 18, 1996 • Burned 4806 hectares of Ponderosa Pine/Douglas Fir at 2,200 m elevation • Severe Erosion following Thunderstorms in 1996 • Stream Flow – Normal < 10CFS • Steam Flow – Storm > 30,000CFS

  3. Project Objectives • Compare effects of single application of biosolids at 0,5,10,20,40 and 80 Mg/ha. • Plant establishment • Biomass production • Species diversity • Chemical quality of Plant and Soil • Runoff quantity and quality

  4. Experimental Design • 24 treatment plots - 6 treatments/ 4 reps. of each • Each plot 3m x 100-300m • Use of Full size Application Equipment • Single application of composted biosolids • disced to depth of 10-20 cm • Seeded at 27 kg/ha (FS provided Seed)
