1.) In the past, sometimes Aboriginal Albertans would purposely set prairie fires in the spring in a type of “controlled burn” in order to begin a secondary succession. Explain why this was done, and why this practice is no longer done.
2.) One of the first species to colonize burned forest is fireweed, a plant that makes a tall stalk of fushia-coloured flowers. Conduct an Internet search to find at least two traditional uses of this plant by Aboriginal peoples.

- INTERPRET DATA Examine Figure 56-24. How many of the sampled species are found in the nonserpentine soil? in the serpentine soil? in the ecotone? What generalization about ecotones do these data support? RESULTS AND CONCLUSION: The various plant species found in the two communities (yellow and blue) and in the ecotone between them (green) are shown in the graph. The ecotone had a greater richness than either adjoining community. SOURCE: Modified from C.D. White, VegetationSoil Chemistry Correlations in Serpentine Ecosystems, Ph.D. dissertation (University of Oregon, Eugene, 1971). Reprinted with permission of Dr. Charles D. White.
