cut made on a tree trunk or branch, opposite from and toward the notch, face cut, or undercut, to complete felling or branch removal. Contrast with bore cut.
process whereby electricity is fed back into downed lines, usually from a home generator that can re-energize the lines. Voltage can be modified if it passes through a transformer.
(1) soil or amended soil used to fill the hole when planting a tree. (2) soil, common fill, aggregates, or contaminants in various combinations put back into an excavation. May not be hospitable for tree root growth and function.
single-celled organisms having a cell wall but no organized nucleus. A few species are plant pathogens.
in rigging, a technique for lowering a limb without allowing either end to drop.
rigging sling(s), usually with at least one spliced eye and a Prusik to position the load line. Used to rig a limb in a balanced configuration.
|balled and burlapped (B&B)||
tree or other plant dug and removed from the ground for re-planting, with the roots and soil wrapped in burlap or a burlaplike fabric. Contrast with bare root, container grown, containerized, and in-ground fabric-bag grown.
dangerous condition created when a tree or branch splits upward vertically from the back cut, slab up.
tree or other plant removed from the ground for re-planting without soil around the roots. Contrast with balled and burlapped, container grown, containerized, and in-ground fabric-bag grown.

cutting away torn or injured bark to leave a smooth edge.
see root barrier and tree protection zone barrier.

|basal bark application||
application of herbicides, usually mixed with penetrating oil, to the lowest 12 to 18 inches (30 to 45 centimeters) of the main stem(s) of unwanted vegetation.
device, often relying on balls or rollers, to reduce friction between mechanical parts such as a wheel or a pulley sheave and an axle or a shaft and case connecting rod. Contrast with bushing.
an auxiliary attachment point on a block or pulley, usually 180 degrees from the main attachment, that is used to reeve the rigging line in a set of blocks.
knot commonly used to join two ends of a piece of tubular webbing to create a loop. See water knot.
means of securing or slowing a climbing line by using wraps around a cleat, carabiner, or other device.
piece of equipment used to provide friction for belaying a climber.
