Key Topics

  • 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.

Learning Objectives

Students should be able to:
1. Identify common trees without a key.
2. Identify specific or unusual species of trees or shrubs through the use of a key.
3. Understand how wildlife habitat relates to: forest communities, forest species, forest age structure, snags and den trees, availability of food and cover, and riparian zones.
4. Understand basic forest management concepts.
5. Be familiar with use of a diameter tape and other forestry tools.
6. Understand the benefits of trees in urban/suburban    settings and the factors affecting their health and survival.

       

Description of Individual Learning Objectives:

1. 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.
2. Forest ecology involving the identification and description of adaptations for common trees associated with forest wetland systems, streamline forest systems, upland forest systems, old field sites, recognizing the different layers of vegetation found within most undisturbed forest stands, recognizing and evaluating variables, related to site such as depth to water table, soils, shade level and their effects related to tree species survival and growth, and recognizing and describing the process of secondary forest succession for old field and harvested sites.
3. Silviculture involving the explanation of the difference between clear-cut harvest and clear-cut silvicultural system, explain the difference between a thinning, diameter-limit cut and the single-tree selection system, understanding and explaining the difference between even-aged and uneven-aged management systems, listing probable reasons why a logger and a forester might select different trees for harvest, defining the goals of thinning in comparison to the goals of final harvest, outlining the goals and approaches used by the major silvicultural systems to insure stand regeneration after harvest, and be able to list at least five best management practices used to control flow of water on a harvest site and describe the situation where they are appropriately used.
4. 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.
5. 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.

 

Critical Facts:

1.

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.

 
2. 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.
3. 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.
4. 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.
