APPLIED SILVICULTURE

Stand Dynamics

Goal: To predict and anticipate the kind of vegetation and the patterns of development following regeneration cuttings and throughout the stand as it ages.

What is an example of a lethal forest disturbance that "kills from the bottom?"

What is an example of a lethal forest disturbance that "kills from the top?"

Define "cohort"

Define "chronological age"

Define "effective age"

What are the 3 general types of age-class structures recognized by silviculturists?

Be able to recognize and understand the stand structures and graphs on page 24.

What are the stages of stand development, AND describe what occurs in each stage.

The gradual decrease in numbers of trees as a stand develops, is the result of competition for light, moisture, and nutrients, and natural selection. (SURVIVAL OF THE FITTEST) The success a tree to win this "race for the sky" is dependent on it’s ability to ____________________ .

Know and be able to distinguish trees in each of the 4 crown classes:

D = CD = I = O (or S) =

What are some management strategies (or problems) for:

Pure, even-aged, single-canopied stands:

Double-cohort stands:

Pure, Uneven-aged or multi-cohort stands:

Mixed Single-canopied stands:

Single-cohort stratified mixtures:

Mixed, Multi-cohort stands:

How does ecosystem management apply to stand dynamics?
