planned program of activities applied to a given stand of forest trees from the period of establishment to harvest time
|
Silvicultural Systems - |
|
an area on which the entire timber stand has been cut |
Clear cutting - |
|
the area necessary to cut over each year to obtain the pre-determined annual cut under a given plan or regulation |
annual cutting area |
|
the average age of the trees which composed the stand |
Stand age |
|
- establishment of forest on an area which is not previously forested |
Afforestation |
|
a bud produced irregularly on older portion of a plant and not on the tip of the stem or in the leaf not connected to the pith of the tree |
Adventitious buds - |
|
- a newly cut-over area regenerated primarily by sprouts
|
Coppice |
|
- a process of producing a stock by rooting of a branch which is first connected with a parent tree |
Layering |
|
cutting done on a stand between the periods of establishment and harvesting |
Intermediate cuttings - |
|
an expression of forest site quality based on the height of dominant stand at an arbitrarily chosen agel |
Site index |
|
the process of conditioning nursery seedlings by subjecting them to conditions to enable them to withstand adverse environmental conditions in the planting site |
Hardening off - |
|
- removing of bark around the stem of the trees so that the flow of carbohydrates in the phloem from the crown to roots is blocked or cut off |
Girdling |
|
- establishment of forest either naturally or artificially upon areas where it is at present, absent, or insufficient |
Forestation |
|
- a type of forest stand where the difference in age of the oldest and the youngest trees does not exceed 20% of the rotation |
Even-aged |
|
- form of branches that often arise in hardwoods or coniferous trees that often develop in naturally pruned boles as a result of the extreme exposure after each cutting |
Epicormic branches |
|
- the quantity of forest products cut on a given forest area in a year |
Annual Cut |
|
the volume of wood which can be cut under the management for a given period |
allowable cut |
|
production of coppice and seedling high forest on the same area by clear cutting the coppice at short intervals at the same time removing of some mature high forest |
Coppice with standard - |
|
- collective term for the entire chemical preparations for killing or suppressing woody plants
|
Phytocides |
|
- the gradual removal of the entire stand in a series of partial cuttings which extend over a fraction of a rotation |
Shelterwood |
|
- removal of mature timber usually the oldest or largest trees either as single scattered trees or in small groups at relatively short interval of time
|
Selection |
|
a tree of sprout origin resulting from the cutting or injury to a small seedling, usually less than 2in. in diameter at the ground line |
Seedling sprout - |
|
removal of mature timber in one cut except for a small number of seed trees left singly or in a small groups which will provide seeds for the next generation |
Seed tree - |
|
a cutting made to remove trees killed or injured badly to utilize merchantable materials before it becomes worthless |
Salvage cutting - |
|
the rotation through which stands should be grown to maintain maximum vigor of growth and reproduction |
Rotation (Silvicultural) - |
|
phase of selective logging concerned with evaluating the result of tree marking after harvesting/logging operation |
Residual inventory - |
|
a sprout arising from a root |
Root suckers - |
|
a systematic activity designed to obtain basic information (physical, biological, socio-economic) about the proposed planting site which are then used in the preparation of a planting plan |
Planting survey - |
|
cuttings done in an area to remove old, mature, defective and undesirable species thus providing adequate space for regeneration |
Reproduction cutting - |
|
refers to the ability of trees cut to produce sprouts on the stump |
Regenerative capacity - |
|
the act of freeing a young stand of desirable trees not past the sapling stage from the competition of undesirable trees that threaten to suppress theml |
Release cutting - |
|
- the natural or artificial restoring of an area with forest trees |
Reforestation |
|
- the removal of live or dead branches from standing trees |
Pruning |
|
cutting of trees that come from the lower crown classes in order to provide openings to lower canopies to permit/encourage development of vigorous seed bearers and to accelerate decomposition of humus layer |
Preparatory cutting - |
|
a detailed systematic statement covering all artificial reforestation activities proposed for each tract of suitable groups of planting areas |
Planting plan - |
|
- a study of life history and general characteristics of the forest trees and stands as they relate to environmental factors
|
Silvics |
|
- the process of aligning slash, debris or other unwanted materials along the contours during the site preparation |
Windrowing |
|
- a loose term which denotes the planting stocks which have germinated and developed to seedling sizes |
Wildling |
|
- term that denotes the removal of all the plants competing with the crop species regardless of whether their crowns are above, beside or below those of desirable species |
Weeding |
|
- means of insuring the needed number of trees for future crop |
Tree marking |
|
- cutting made in an immature stand in order to stimulate the growth of the trees and to obtain greater total yield of useful material |
Thinning |
|
- an indication of the number of trees in a stand as compared to the desirable number for best growth and management |
Stocking |
|
a sprout arising from a bud developing in a tissue or a wound callus on the stump |
Stool shoots - |
|
- a branch of forestry which deals with the establishment, development and protection of forest |
Silviculture |
|
tree permitted to remain at the area after the cutting in a coppice forestl |
Standard tree - |
|
- an aggregation of trees or other growth occupying a specific area and sufficiently uniform in composition, age arrangement and conditions as to be distinguishable from the forest |
Stand |
|
productive capacity of the forest |
Site quality - |
|
- a shoot formed from the dormant buds at the base of the trees |
Sprout |
|
activity involving the treatment of the soil and the ground cover by hand, machine, chemicals, fire or combination of these for favorable reception to either naturally or artificially sown seeds or planted stocks |
Site preparation |
