Thinning. An arboriculture term used to describe selective pruning to reduce density of branches and foliage.
Thinning. Use water, do not reduce solution beyond three parts water to one part Galva‐Etch.
Thinning. Although small diameter limbs may be pruned where the contractor desires, it will not be necessary to make cuts smaller than one inch in diameter, other than where branches may be shortened to accommodate clearance beneath the canopy. Thinning is to include the following: remove dead or broken limbs one inch in diameter or larger; if two limbs are crossing or touch each other, shorten or remove one of them; if two limbs (one inch diameter or larger) originate within twelve inches of each other on the trunk, shorten or remove one of them. CROWN REDUCTION Clearance from traffic lights / signals, street lights, photo cells (lamps / street lights), signs or other structures shall be to a minimum of five (5’) feet or as practical. Use directional pruning where possible so future growth is directed away from said structures. Pruning techniques Pruning shall be in accordance with ANSI A300 pruning standards with proper arboriculture practices as established by the National Arborist Association and done in such a way as to not disfigure or jeopardize the health of the tree. In unique situations it may be necessary to use heading cuts back to ANSI A300 appropriate location on branches. However, heading cuts are not preferred and topping is strictly forbidden. Equipment Climbing spurs, gaffes, or spikes in the act of pruning is prohibited Equipment and work practices that damage bark or cambium should be avoided. Rope injury from loading out heavy limbs should be avoided.
Thinning. While thinning, take care not to disturb surrounding landscape. Trim and edge as necessary to restrict growth from encroaching on to sidewalks, curb or where pedestrian traffic may occur. Not all shrub or groundcover is intended to be trimmed on a weekly basis. The Contractor is responsible to review the aforementioned plant specifications as to the nature of how individual plant groups shall be maintain. In addition, a pre-conference meeting with the Owner and the Owner's representative shall describe in detail any special circumstances relative to the site.
Thinning. After binarization, thinning [7] process is applied over the image, which reduces the thickness of all ridge lines to a single pixel. In the proposed method, central line thinning methodology is used.
Thinning. Primer may be thinned only if recommended by the manufacturer, done in strict compliance with the manufacturer’s instructions in the presence of the Engineer. Paint Application. Paint shall be applied using brush and roller methods. Spraying will be allowed only on areas which the Engineer deems inaccessible by brush or roller methods. Complete protection from paint spatter, spillage, over spray, windblown paint, or similar releases of paint shall be provided. Covers, tarps, mesh and similar materials shall be placed around the work area to protect public and private property, pedestrian, vehicular, marine or other traffic, all portions of the bridge, highway appurtenances, waterways, and similar surrounding areas and property, upon, beneath or adjacent to the structure. All areas cleaned shall be painted with one coat primer to overlap old/existing paint no less than one inch. Film Thickness. Primer shall be applied in sufficient quantity so as to produce a minimum dry film thickness of 2.0 mils.
Thinning. Paint may be thinned only if recommended by the manufacturer, done in strict compliance with the manufacturer’s instructions, approval by the Engineer and mixed in the presence of the Engineer. Paint Application Paint may be applied using brush or roller methods. Spraying will be allowed only on areas which the Engineer deems inaccessible by brush or roller methods. Complete protection from paint spatter, spillage, overspray, wind-blown paint, or similar releases of paint shall be provided. Covers, tarps mesh, and similar materials shall be placed around the work area to protect public and private property, pedestrians, vehicular, marine or other traffic, all persons at the bridge, highway appurtenances, waterways, and similar surroundings areas and property, upon, beneath, or adjacent to the structure. All areas previously primed shall be painted with one coat of intermediate paint to extend beyond the primer coat no less than one inch. ITEM 290570.960210 MAINTENANCE PAINTING INTERMEDIATE COAT (SPRAYING PROHIBITED) Film Thickness Intermediate paint shall be applied in sufficient quantity so as to produce a minimum dry film thickness of 2.0 mils.
Thinning. The cutting of trees to meet a short term desired stand condition (i.e. species composition and stocking level).
Thinning. Overstocked even-aged stands will be thinned, where appropriate, to redistribute the growth potential of the site to fewer conifer trees. When such an operation occurs in a very young stand (approximately 15 years old), it is called precommercial thinning. Stems are cut down and left on the site to decay. Commercial thinning requires preparation of a THP and may occur in stands as young as 35 years. Leave trees (i.e., the trees that will be retained) are selected to ensure that they are evenly distributed throughout the site and have the potential to take advantage of the increased growing space. The harvested trees are yarded to a landing, loaded onto trucks, and transported to a processing facility.
Thinning. Removing trees and brush to reduce stand density. See Appendix E for a discussion of thinning techniques.
