A fir tree snag among living fir trees. In forest ecology, a snag refers to a standing dead or dying tree, often missing a top or most of the smaller branches.In freshwater ecology it refers to trees, branches, and other pieces of naturally occurring wood found sunken in rivers and streams; it is also known as coarse woody debris.

Snagging chinook salmon. Snagging, also known as snag fishing, snatching, snatch fishing, jagging (Australia), or foul hooking, is a fishing technique for catching fish that uses sharp grappling hooks tethered to a fishing line to externally pierce (i.e. "snag") into the flesh of nearby fish, without needing the fish to swallow any hook with its mouth like in angling.
When a snag occurs in certain fine textiles like pantyhose, it is called a run. This is because the snag breaks at least one fibre, causing the knit to come undone in a line which runs up the grain of the fabric. In clothing, snags can also occur in coarse textiles like sweaters, or in certain types of sport jerseys such as for soccer (football).

A relative measure of fire-control difficulty; doubling the index means twice the effort may be needed to control the fire. burn out Setting fire inside a control line to consume fuel between the edge of the fire and the control line. burning period The part of each 24-hour period when fires spread most rapidly, typically from 10:00 AM to sundown.
Plant species richness of snag forests can be much higher than in unburned forests. [3] Bird and small mammal communities that utilize complex early seral forests forage on the abundant insects and increased abundance of seeds in the post-fire flora. [9] [11] These species, in turn, support an increase in raptors. [12]
Use of low snag equipment configurations (avoid dangling gear and snap hooks that can snag on lines). Overhead environment (cave, wreck or ice, where direct ascent to the surface is obstructed) Diver may get lost and be unable to identify the way out, and may run out of breathing gas and drown. [23] Inappropriate response due to panic is possible.
