Biomass and Production Learning Objectives

Learning Objectives

After completing this module, students will be able to:

  1. Define biomass and differentiate between the terms that are used to describe the weight of plant material in a unit area.
  2. Explain why biomass data are meaningful from both ecological and management perspectives.
  3. Describe the situations or applications in which biomass measurements are used.
  4. Describe the kinds of decisions about ground rules (such as plant parts measured, height for clipping or estimating, separation of live and dead material, etc.) that must be determined to when measuring biomass.
  5. Differentiate between the main methods used to measure biomass, including harvest methods, estimation methods, double sampling methods, and indirect methods, and explain the advantages and disadvantages of each approach.
  6. Calculate dry weight correction factors used to adjust estimated fresh weights to dry weights.
  7. Use regression analysis to adjust estimated fresh weights based on harvested weights collected with a double sampling approach.
  8. Given a small data set, analyze and interpret biomass data collected with different methods.
