Lesson Overview: Students use the stand history diagrams that they assembled in the 2 previous activities to learn about mixed-severity fire regimes. They check their skill in identifying historical fire regimes by interpreting stand history diagrams. Finally, in the assessment, they describe or depict the appearance of a forest that has had a historical regime of low-, mixed-severity, or stand-replacing fire.

Lesson Goals: Understand the nature of low-severity, stand-replacing, and mixed-severity fire regimes. Be able to interpret stand history diagrams showing these regimes and to envision a forest stand based on its fire history.

Objectives:

• Students can identify historical fire regimes from stand history diagrams.
• Students can describe or depict the appearance of aforest that has experienced a specifichistorical fire regime.
