context_page_description: NCF-Envirothon is an annual environmentally themed academic competition for high school aged students organized by the NCF-Envirothon a program of the National Conservation Foundation. The competition is held by the United States and Canada on a regional, state, and bi-national level. Envirothon combines in-class and hands-on environmental education in a competition setting which involves a problem-solving presentation as well as written field tests. The competition tests students on five core subjects- aquatic ecology, forestry, soils and land use, wildlife- along with a fifth annually-changing subtopic which focuses on relevant environmental issues. Currently, roughly 500,000 students from forty-five U.S. states and nine Canadian provinces/territories participate in the competition.
  States and provinces across the United States and Canada each have their own local competitions from which the winning high school team earns the privilege of representing their state/province at the NCF-Envirothon competition, held each summer in a different U.S. state or Canadian province.
