Unit 3: Land and Water Use Checklist of Objectives Practice Questions  How alternative agricultural methods- 1. Design an integrated pest management scheme for a small including integrated pest management, no-till vegetable garden in a city lot behind a house. How would this agriculture, mixed cropping, and other scheme differ from integrated pest management used on a methods of soil conservation can provide large farm? What aspects of IPM could not be used? How major environmental benefits might the artificial structures of a city by put to use to benefit IPM? 2. Under what conditions might grazing cattle be sustainable when growing wheat is not? Under what conditions might a herd of bison provide a sustainable supply of meat when cows might not?  The difference between how limiting factors 1. You are sent unto the Amazon rain forest to look for new affect agroecosystems verus ecosystems. crop species. In what kinds of habitats would you look? What kinds of plants would you look for? Could the rainforest soil be assimilated?

 Describe the possible benefits and drawbacks 1. Should genetically modified crops be considered of genetically modifying crops acceptable “organic” farming? Explain. 2. You are about to buy your mother a bouquet of 12 roses for Mother’s Day, but you discover that the roses were genetically modified to give them a more brilliant color and to produce a natural pesticide through genetic energy. Do you buy the flower? Explain your reasoning and justify it using what you understand about genetic modification.  Describe the ecological services that are 1. Can a wilderness park be managed to supply water to a provided by landscapes of various kinds city? Explain. 2. What are the environmental effects of decreasing the rotation time (accelerating the rate of cutting) in forests from an average of 60 years to 10 years? Compare these effects for (a) a woodland in a dry climate on a sandy soil and (b) a rain forest.

1. What environmental conflicts might arise when a forest is  Describe the basic principles of forest managed for the multiple uses of (a) commercial timber, (b) management as well as the role that parks and wildlife conservation, and (c) a watershed for a reservoir? In nature preserves play in the conservation of what ways could management for one use benefit another? wilderness 2. In a small but heavily forested nation, two plans are put forward for forest harvests. In Plan A, all the forests to be harvested are in the eastern part of the nation, while all the forests of the west are set aside as wilderness areas, parks, and nature preserves. In Plan B, small areas of forests to be harvested are distributed throughout the country, in many cases adjacent to parks, preserves, and wilderness areas. Which plan would you choose?

 Describe the importance of habitat, 1. Describe an ecological island you have visited. Which ecosystems, and landscape in the conservation species are most vulnerable to local extinction? of endangered species 2. Why are we so unsuccessful in making rats an endangered species?  Steps we can take to achieve sustainability of 1. Of the eight justifications described in chapter 13, which wildlife, fisheries, and endangered species apply (if any) to the following organisms: black rhino, Furbish Lousewort (small rare flower), newly discovered beetle, smallpox, wild strains of potatoes, and the North American eagle. 2.  Describe the concepts of species persistence, 1. Describe an ecological island you have visited. Which maximum sustainable yield, the logistic species are most vulnerable to local extinction?
