A fire has swept through a mature forest and devastated the area. Virtually all vegetation is burned and considered a complete loss. Foresters, however, realize that plants will soon colonize the area starting the successional process that will eventually restore the forest. Will the pioneer plants that first colonize the area most likely be r-selection strategists or K-selection strategists?
Explain your answer.
What will be an ideal response?
The best answers should address the fact that r-selection species reproduce quickly, with a large number of individuals. Therefore, they can quickly colonize a new area out competing a K-selection species that reproduces much more slowly and have fewer offspring. Pioneer species are often r-strategists and very important in early succession.
