  1. * Carbohydrates and lignin analysis completed after successive extractions with water and ethanol.
  2. **BKLPP refers to Beetle-killed lodge pole pine white wood; IFS is Interface Fire Slash (or Forest Thinnings); LR refers to Logging Residue.
  3. HOG I & II are two different types of hog fuels collected from Nippon Paper. Hog I is more bark intensive. Bark samples are sourced from lodge pole pine wood.
  4. ***Values in the bracket represent the deviations of triplicate analysis.
  5. ****Ash values reported are from biomass samples prior to extraction.
