This part of the activity focuses on the practice of setting aside natural areas for ecological, cultural, and recreational purposes. In some wilderness areas, human use of the area is kept to an absolute minimum. But, it can be expensive and difficult to maintain wild areas with little human influence. The areas are so beautiful that they attract many visitors, who in turn can harm the natural attraction itself. Vehicles can be a particularly difficult problem in natural areas such as this. Yellowstone Park was established in 1872 and has more than 2.2 million acres. It remains one of the most popular units of the U.S. National Park system and has more than 3 million visitors each year. Instructions Review the Case Study at the beginning of Chapter 12, entitled “Protecting Forests to Prevent Climate Change,” and Section 12.3, entitled “Parks and Preserves.” Consider reasons it is important to maintain forest ecosystems. Open Google Earth, and in the search box enter Old Faithful, Yellowstone National Park, WY. Click Search. According to the textbook, how and why did Stephen Mather, the first U.S. National Park Service director, encourage tourist use of the parks? What were some positive and negative results?

This part of the activity focuses on some of the key methods that have been useful in protecting endangered species and protecting biodiversity, including hunting and fishing regulations, creating parks and refuges, the Endangered Species Act, and recovery plans that aim to protect the habitat of rare or endangered species. As an example, there are many rare and unique species of both plants and animals in New Zealand. Nearly 1,000 years ago, though, colonists to the area introduced rats and other invasive species of plants and animals that began to harm the native ecosystems. At Kapiti Island, a recovery plan created a wildlife refuge, eliminated the non-native species such as goats, pigs, rats, and dogs and brought back native plants and animals such as the Kiwi bird. Instructions Review the Case Study at the beginning of Chapter 11, entitled “How Can We Save Spotted Owls?” and Section 11.1, entitled “Biodiversity and the Species Concept” and Section 11.2, entitled “What Threatens Biodiversity?” Spotted owl populations have suffered from habitat destruction, while native species in New Zealand have suffered from invasive species; these are two types of threat to biodiversity. Consider other threats as put forth in Chapter 10, as well as the implications of biodiversity loss for humans. Open Google Earth, and in the search box enter: Kapiti Island, Wellington, NZ. Click Search. 1. How big is Kapiti Island? Zoom way in and explore the island some. What evidence is there that this island is being preserved as a natural area?
