How does a log jam happen?
Log jams form when trees floating in the water become entangled with other trees floating in the water, or become snagged on rocks, large woody debris, or other objects anchored underwater.
How do you get rid of log jams?
Logjams may be disposed of by removing them from the floodplain and/or wetlands, or by piling and cabling logs at secured areas, as appropriate, with minimum amount of disturbance to vegetation.
What is an engineered log jam?
Engineered log jams are structures created in streams, rivers and floodplains designed to simulate the function of naturally occuring log jams. While engineered log jams are temporary, they provdie habitat services, until riparian forests can grow the large trees to allow for natural formation of log jams.
What do log runners do?
Log driving is a means of moving logs (sawn tree trunks) from a forest to sawmills and pulp mills downstream using the current of a river. It was the main transportation method of the early logging industry in Europe and North America.
Why do loggers yell timber?
The short answer to your question (my ride is honking out front) is that lumberjacks shout “Timber!” to warn anyone in the vicinity that a big tree is on its way down.
How did Old Time Loggers break up log jams on the river?
In the winter, lumberjacks would use chains to pull cut timber to a frozen river, where they would stack it. When spring came, the river would thaw and workers — called river drivers — would float the logs down the river. Log jams were common in areas with shallow water or bends in the river.
What is timber jam?
1 : a jumble of logs jammed together in a watercourse. 2a : deadlock, impasse trying to break the logjam in negotiations.
Why are logs stored in water?
Storing logs under sprinklers or in a log pond helps prevent end checking and slows deterioration caused by insects, fungal stain, and decay. However, chemical staining can occur under wet conditions. Today, softwood logs decked in the log yard are typically protected by water sprinkling during warm weather.
Why are logs kept in water?
Why are sunken logs worth so much?
Trees become submerged by slipping from a logger’s grasp or by growing in a valley previously dammed for reservoir construction. Very few of these old growth trees remain legally accessible for harvest today, which makes the sinker logs that much more desirable.
