More than 265 teenagers from 44 states and nine Canadian provinces are at NAU to participate in North America’s largest high school environmental education competition, the 2008 Canon Envirothon.

Throughout the competition, teams—including a contingent from Sinagua High School in Flagstaff—will be tested on their knowledge of soils and land use, aquatic ecology, forestry, wildlife and a current environmental issue.

This year’s topic for the competition is “Recreational Impacts on Natural Resources.” Students will analyze long- and short-term environmental, social and economic factors relative to recreational impacts upon natural resources and their management.

As they continue to learn about environmental issues affecting natural resources, participants will have the opportunity to compete for a share of more than $125,000 in educational scholarships, as well as Canon products.

The competition, which runs through Aug. 3, is organized by the National Association of Conservation Districts in the United States, the U.S. Forest Service and the Natural Resource Conservation Service.
