2016 Envirothon Team! Ashleigh Crum, Rob Tabaracci, Sarah Mad Plume, Kip Giddings, Dexter Clark
2015 Envirothon Team! Caleb Noble, Jayden Peterson, Landen Beckner, Megan Keys, Summer Diegel
The Envirothon Team is made up of 5 members. We meet weekly at lunchtime in Room 232 every Tuesday. On the third week of April, we travel to Lewistown for the state competition. Students are tested on their knowledge in five topic areas: soils and land use; aquatic ecology; forestry; wildlife; and a current environmental issue that changes each year. Through the program, students develop an understanding of effective teamwork, resource management and ecology. At the same time, they gain valuable exposure to a range of disciplines while exploring possible career paths.

Key Topics/Learning Objectives

species may have for those environments.
- Learn the different types of aquatic and wetland ecosystems in a watershed determining components.
- Learn major human impacts on water quality and quantity and develop an understanding of management practices which can reduce of eliminate adverse impacts on the water resource. Learn to identify major sources of point and non-point source pollution. Learn the major impacts of impaired water quality on humans, livestock, and wildlife.
- To expand an awareness of basic hydrology and the watersheds including determination of water discharge and recharge areas and an understanding of a water budget.
- To learn the basic measurement methods for indicators of water quality and how to apply these methodologies.
- To learn the basic physical and chemical properties of water. A basic knowledge of how these properties effect the geological features that come in contact with water. Chemical properties that should be reviewed would include, but are not limited to alkalinity, osmosis, hardness, total dissolved solids, and dissolved oxygen should familiar to the participants. Physical properties that should be reviewed would include but are not limited to conservation of energy, sediment transport, energy grade lines.
- Basic Forestry Knowledge; such as tree identification, silvics of
common trees, tree measurement and tool use, and interaction of forests and environment.
- Forest Ecology; such as the observation and identification of forest types, observing and describing forest stand structure, observing and
describing site variables that affect tree species, and observing and identifying the stages of forest succession.
- Silviculture Systems- such as describing the difference between harvesting and silvicultural systems, describe the difference between the goal of thinning and final harvest, describe the purpose of common silvicultural systems, and describe the management practices and their purpose.
- Viewing Ecosystems; such as the observation of how trees and forests impact soil development, wildlife habitat, public places, agriculture, and on water quality.
- Urban Forestry; such as the recognition of the value of trees in the urban landscape, choosing the correct species for specific locations, energy conservation through three plantings, urban wildlife benefits from tree plantings methods, proper tree care and maintenance, including wise choices in pest and disease control.

Description of Learning Objectives:
- Basic forestry knowledge involving the use of leaves, bark or twigs to identify common tree species of Montana (using a key if necessary), understanding rooting habit, shade tolerance, soil, and other characteristics of common tree species, identify and use such tools as a Biltmore stick, abney level or clinometer, prism or angle gauge, calculating the annual diameter growth by using annual ring measurements, understanding and explaining the use of basal area in forest management, and describing the effects of trees and forest on temperature, wind, sounds, and other variables.

- The viewing of ecosystems where the goal at each site is to assess the whole area while addressing questions on the various components you are asked to observe and understand.
- To understand the importance and benefits of trees in the urban habitat for a wide variety of reasons, including wildlife habitat, windbreaks, energy conservation, shade benefits, erosion control, aesthetics and others. To understand proper care of trees in the urban environment.
- Trees and forests occur in certain locations for certain reasons that are often identifiable by observing the site and the larger area surrounding the site. These may be as simple as the soil type, the amount of soil moisture, or need for a park or natural area within a residential area.
- Highly productive soils are often used for agricultural production and would also support a highly productive forest. As sites become less acceptable for agriculture due to drought or wet soils, certain tree species and forest types can still maintain high levels of productivity on many of these sites.
- As the amount of soil moisture on a site increases, there is a change in the types of vegetation that become dominant. Wetland sites have special combinations of tree species, shrubs, and herbaceous plants that are part of the important functions these sites contribute to the environment.
- Wildlife habitat is affected by the age, size, density, variety of tree species, and location of the trees or forest stands in relation to surrounding ecosystems such as residential areas, other wooded areas, streets and water sources. The level of importance of trees is dependent upon the ecosystem (prairie, wetland, agricultural field, forest) and the wildlife being studied.
