Envirothon is an annual environmentally themed academic competition for high school aged students organized by The North American Envirothon Organization. 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 Canon Envirothon competition, held each summer in a different U.S. state or Canadian province. In areas with a considerable number of teams, subdivisions such as county, regional, or district competitions are also held. Teams must win these intermediary competitions in order to move on to the state/province levels.
Organizers and Sponsors 
The North American Envirothon is a 501(c)3 Nonprofit organization headquartered in League City, Texas. Coordinating the delivery of the North American competition, the organization also relies heavily on volunteers across North America to advise individual teams from each participating state and province. Governing the program is the North American Envirothon Committee, which is made up of one representative from each participating state and province, as well as an Executive Director and elected Board of Directors.
Envirothon is sponsored by Canon USA, the National Association of Conservation Districts, the United States Forest Service, the Natural Resources Conservation Service, and the National Conservation Foundation. Individual teams are often sponsored by school clubs or classes, local businesses and governments, or 4H and other such non-scholastic organizations.
Competition participants are generally teams of five students with one to two team advisers. Home-schoolers can also take part as their own team.
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 North American Envirothon Competition, held each summer in a different U.S. state or Canadian province. In regions with a considerable number of teams, competitions on subdivision, county, regional, or district levels are also held. Teams must win these intermediary competitions in order to move on to the state/province levels. At the North American Competition, teams that rank first through tenth receive prizes and scholarships of various values.
Competition week at the North American Envirothon level includes various workshops, field trips, and seminars led by professionals and educators for both the students and their advisors. Most of these outings are linked to the current issue topic and provide information on the area in which the competition is being held.
During the competition, each team must complete five written field tests, each dealing with a different topic. These tests consist of various question types, including identifications and hands-on assessments. Each team must also prepare an oral presentation on the current issue topic, which the team presents to a panel of judges. An important element of the competition is the understanding that each topic is interrelated, and understanding human effects on the environment and how human activities connect with ecosystem functions. Each test is scored out of 100 points, with the presentation being scored out of 200 points. The team with the highest cumulative total of points at the end of the scoring is the winning team. Recognition is also given to teams with the highest scoring in each of the five categories.
Competiton Locations 
The location of the North American Competition is determined based on a regional map that separates North America into five general regions: Far West, Mid-West, Southeast, Northeast, and Far North. The host college or university is usually located in a different region than that of the year preceding it. For example, the most recent competition was held at Susquehanna University in Selinsgrove, Pennsylvania in the Northeast, and the 2013 competition will be hosted by Montana State University in Bozeman, Montana in the Far West.
Present Competition 
The 2013 North American Envirothon competition will be held August 4–10, and hosted by Montana State University in Bozeman, Montana. 45 States and 9 Canadian Provinces and Territories are registered for the competition so far. The current Issue Topic for this year's competition is Sustainable Rangeland Management: Achieving a balance between Traditional Agricultural Uses with Non-Agricultural uses on Montana Rangelands. This will be the first time that the state of Montana hosts the North American Competition.
Competition Topics 
Each field test dealing with one of five competition topics requires both theoretical understandings and hand-on skills such as identification and chemical testing. Each topic also has a degree of relatedness to one another, which is sometimes considered in theoretical-based test questions.
Aquatic Ecology 
- Learning objectives includeabiotic and Biotic factors, aquatic environments, and water protection and conservation, among other topics.
- The field test deals with these learning objectives, with focuses on the functions and significance of watersheds and wetlands; the connections between Water quality and aquatic organisms; and Water use, regulation, and threats such as Invasive species.
- Hands-on tasks conducted during the field test include identification of wetland types and species, outlining a watershed on a Topographic map, and performing chemical water quality tests.
- Learning objectives includetree and shrub physiology, Forest ecology, sustainable Forest management, and trees as important renewable resources, among others.
- The field test also focuses on forest structure in relation to biotic and abiotic factors; Silviculture techniques and tool use; and the identification and management of invasive species and diseases.
- The test's hands-on portion includes various tasks such as tree and leaf/needle identification, collecting tree core samples using an Increment borer to determine tree age and historical influences, and Tree planting using proper techniques.
Soils and Land Use 
- Learning objectives include physical properties of soil and soil formation, soil ecosystems, chemical properties of soil, soil conservation and land use management, and soil surveying, among others.
- Within these objectives lie focuses on identifying and understanding soil profiles and horizons; chemical properties and balances of soil; and understanding soil data, surveys, and Drainage and their relations to soil use.
- The field test includes hands-on tasks such as soil type and texture identification, outlining the different horizons in a soil profile, and performing chemical soil property tests.
- Learning objectives for the Wildlife field test include knowledge of wild birds and mammals, wildlife ecology, conservation and management of wildlife, and issues involving wildlife and society, among other objectives.
- Other topic focuses include understanding food habits and skull morphology of wildlife species; habitat features and influences; wildlife adaptations; and predator/prey relationships and Carrying capacity of ecosystems; and how humans, Introduced species, and diseases affect wildlife.
- Hands-on tasks conducted during this test include using an identification key to identify wildlife pelts, skulls, footprints, and calls/sounds; and using Global Positioning System to track tagged specimens.
Current Issue 
- The fifth topic changes annually, and deals with issues affecting present-day society and environment.
- The Current Issue field test focuses on theoretical understandings of the issue in relation to the other four competition topics, as well as some hands-on activities. Current Issue Topics have included Nonpoint source pollution/Low Impact Development (2012), Salt and Freshwater Estuaries (2011), Protection of Groundwater Through Urban, Agricultural, and Environmental planning (2010) and Biodiversity in a Changing World (2009), among others in earlier years.
In 1979 the Pennsylvania Soil and Water Conservation Districts set up the Environmental Olympics, later renamed Envir-Olympics, to encourage interest in environmental issues through hands-on competition. Expanding rapidly to include forty conservation districts by 1987, it gained attention from other states, and in 1988, the program became the National Envirothon, with participation from Pennsylvania, Massachusetts, and Ohio. In 1992 Nova Scotia became the first Canadian province to join the competition. The competition was sponsored by various state, local, and provincial conservation programs and associations until 1997 when Canon Inc. began its support of the program, with local sponsors still supporting lower level competitions. In 1999 Canon became the title sponsor of the competition between the U.S. states and Canadian provinces, with the competition being renamed the "Canon Envirothon." It is currently referred to as the "North American Envirothon."
