You will see a sequence of slides in pairs. The first picture will show a forest unburned, and then it will show the forest burning. Observe the age and stage of the forest carefully in the first slide. In the next slide, watch the details of how the forest burns.

FORESTS and FOREST FIRESFORESTS and FOREST FIRES

Our National Forests have many purposes, but they are frequently managed for lumber. That means our National Forests have different ages. Please advise the Forest Service about what fire dangers they will find in different locations. Write a 1-3 paragraph essay about succession and forest fires. Be sure to include a chart of your observations.
