Lesson Overview: Students use information from 11 cross-dated increment cores to figure out the approximate age of a forest stand that originated after stand-replacing fire.
Lesson Goals: Understand how scientists can determine the time when a stand-replacing fire occurred. Be able to assemble and interpret a stand history diagram and discuss evidence for a stand-replacement fire regime.
- Students can follow technical directions in order to record observations and help assemble a stand history diagram.
- Students can describe the fire history shown by a stand history diagram that contains 2 cohorts of trees.
