Forestry Aesthetics

Over the next few weeks, we will be featuring a series on forestry aesthetics loaded with information for any landowner to use.  In order to better understand the series, we felt it would be beneficial to start with a glossary of terms.  Some are very familiar and some aren’t but all are important to know with regard to your forest and maximizing your landownership experience.

Aesthetics Management Zone (AMZ) – An area of land, typically along a roadway or water body, in which forestry is practiced in a manner sensitive to the aesthetics of an area.

Band Treatment – The application of fertilizer or herbicides in areas only as wide as the planting bed or within a few feet of either side or a planted tree.

Broad-based dip – A surface drainage structure designed to convey surface water runoff off a road while allowing vehicles to maintain normal speeds.

Broadcast application – The application of fertilizer or herbicides over an entire treatment site, usually via helicopter or airplane.

Clearcutting – The total removal of a merchantable tree crop from an area.

Contour – An imaginary line on the land surface that is at a constant elevation.

Crowning – The slight building up of the middle section of a road so that surface water flows off the sides.

Dispersal – The dissipation or disappearance of smoke.

Dog-legged roads – Roads that are curved away from the line of sight thus reducing the line of sight length.

Erosion – the detachment and movement of soil particles.

Feathering – The utilization of partial harvesting techniques between clearcuts and remaining stands of trees to reduce the appearance of change between harvested and non-harvested sites.

Flyovers – Helicopter or airplanes flying outside of the prescription zone at low altitudes.

Greenup period – The time required for vegetation to cover a site after harvesting or prescribed burning.

Group Selection – A method of harvesting timber wherein a designated group(s) of trees is removed. Groups may be determined by size, age, species, or other defined criteria.

Low impact – Modifier term used to identify forest practices which minimize actual or apparant changes to the landscape.

Low impact prescriptions – Forest practices, such as logging, that impact the site only minimally.

Patch clearcuts – A tree regeneration method whereby all of the merchantable trees in a relatively small area are removed.

Piling – Pushing logging debris into piles.

Reforestation – The re-establishment or restocking of a forest through natural regeneration or artificially planted seed or seedlings.

Revegetation – The growth of new herbaceous or woody vegetation on an area that has been cleared.

Rutting – Impressions left in the soil as a result of the passage of heavy equipment.

Sediment – Accumulation of soil particles which have been detached and transported by water during the process of erosion.

Shelterwood – A harvest method for regenerating a site that involves the gradual removal of the residual stand in a series of partial cuts. A new forest is established before the complete removal of the parent stand.

Site preparation – A forest activity to remove unwanted vegetation and other material to cultivate or prepare the soil for reforestation.

Skid trails – A temporary pathway for dragging felled trees or logs to a log deck or landing for processing.

Slash – Unmerchantable wood residue, usually brush, tree limbs, tops, or leaves that is left following a commercial timber harvest operation.

Smoke sensitive area – Areas that are sensitive to smoke, such as urban areas and well-traveled highways.

Spot treatment – A localized application of fertilizer or herbicide.

Staging areas – Specific base location where a helicopter or airplane loads fertilizer or herbicide.

Streamside Management Zones (SMZs) – An area adjacent to the bank of a stream or body of open water where extra precaution is necessary to carry out forest practices in order to protect bank edges and water quality.

Strip clearcuts – The total removal of merchantable tree crop from an area in strips.

Thinning/Selection – Removing some of the trees from a stand to encourage growth among the remaining timber.

Topography – The delineation of an area that shows its relative position and elevation; the lay of the land.

Utilization – The degree to which trees are removed and merchandized during the harvesting process.

Viewsheds – The view of a landscape from a particular vantage point.

Waterways – Any bay, branch, brook, canal, creek, lake, pond, river, reservoir, slough, sinkhole, or other natural or man-made watercourse which flows within a defined channel or is contained within a descernible shoreline.

Windrowing – The act of raking logging debris and unmerchantable woody vegetation and piling it in rows so that the debris can decompose or be burned and the site reforested more efficiently.

Wing ditch – A secondary drainage structure that diverts drainage water from primary roadside ditches to be filtered out into the surrounding area to minimize erosion.
