Lesson Overview: In this activity, students extract seeds from serotinous cones, count them, and estimate the number of seeds that might fall in an area after a large, severe fire.
Lesson Goal: Students will understand that Baker cypress and knobcone pine cones are serotinous and need wildland fire to open their cones and release their seeds. Thus they can establish a new forest after fire.
- Students can identify filled vs. empty seeds.
- Students can explain the importance of fire and serotiny for regeneration of knobcone pine and Baker cypress.
