Forestry key points

Forestry learning objectives Standard of Learning
1. Identify common trees without the use of a key. ES 7; LS 5; BIO 7
2. Understand how the following issues are affected by forest health, and
management: Biological diversity, forest fragmentation, air quality,
aesthetics, fire, water quality, recreation and supply of wood products.
BIO 5,7,9; LS
4,5,6,7,8,9,
10,11,12,14
3. Know how to recommend management practices based on landowner
objectives, site and forest stand evaluations, and a forest inventory.
This requires an understanding of silvicultural concepts and forest
management practices, such as harvest methods and best management Practices.
BIO 1,5,7,9; PS 1,
ES 1,2,3; LS,4,5,6,
7,8,9,10,11,12,14
4. Know how to conduct a forest inventory. This requires and understanding
of the use of tree measuring devices: clinometer/abney level, diameter
tape, Biltmore stick, and land area measurement techniques
and terms: acres, chains, pacing, topographic maps, compass.
BIO 1; PS 1; ES
1,2,3; LS 4,5,
6,7,8,9,10,
11,12,14
5. Know how to conduct a site evaluation to determine its suitability for
growing trees. This requires an understanding of the relationship between
soil depth, slope percent, aspect, slope position and their effects on the
growth and ecology of trees.
BIO 3,5,7; LS
4,5,6,7,8,9,10,
11,12,14
6. Know how to conduct a stand evaluation, especially as it relates to forest
management practices. This requires an understanding of disturbance
factors, such as grazing and fire, forest type, stand origin, stocking and the size distribution of trees.
LS 4,5,6,7,8,
9,10,11,12,14;
BIO 7,9
7. Know how to calculate the board-foot volume of timber and the dollar value of that timber per acre, based on a 1/10th acre plot sample. A calculator will be helpful. BIO 1,9; PS 1;
ES 1,2,3; LS 4,
5,6,7,8,9,11,12
8. Understand the issue of "introduced species and their effect on biodiversity" as it affects the health of native forests. Determine what management measures may be taken to protect native species, stands and habitats.
LS 4,5,6,7,8,9,
10,11,12,14;
BIO 1,3,5,7,9;
9. Understand how wildlife habitat relates to: forest communities and riparian
zones (forest species, age, structure, food availability, cover, nesting, etc.)
