Timber rafting is one of the most important ways to transport felled timber, which uses the natural ability of a tree to stay afloat in the water. There are many ways to organize timber rafting. In Soviet times, it was practiced, including the now banned mole rafting of trees. It's time to talk about it and find out if this method really caused damage to the environment?
In most cases, mole rafting of felled wood is carried out during the spring flood. The main feature of this method is to carry out the transportation of cut wood in an unbound state. Mole rafting is used on the primary river network only in cases where no other method of transporting trees can be applied. To guide the forest along the river, special guide structures are installed on it - booms. Traps are installed at the destination to stop the forest.
In addition to the mole alloy, two more methods are widely practiced. The first is the koschevy rafting of the forest. The essence of this method lies in the fact that all transported logs are enclosed in special floating structures that do not allow them to "spread" all over the river, sink and wash ashore earlier term. The second way is raft alloy. The name of the method speaks for itself: with this approach, rafters knit huge rafts from trees.
The fact that the mole alloy is not only ineffective, but also potentially harmful to nature, began to be discussed back in the Soviet Union. Lumberjacks did not like this technique, first of all, because it was not overwhelming, but still quite solid. part of the logs sank or was thrown ashore, i.e. actually lost during transportation due to loss of buoyancy tree. Soviet scientists were worried that the logs that fell to the bottom would clog the bottoms of the rivers, which would later have to be cleaned.

Ecologists began to sound the alarm only in the early 1980s. At that time, it became quite obvious that it was impossible to continue using the mole alloy. Clogging of rivers harmed not only the environment, but also undermined economic activity, as it made it impossible for ships and barges to pass. So, for example, on the Pinega River, due to the clogging of the fairway as a result of mole rafting, today, for the most part, only ferries from one bank to the other can sail. As a result, the mole alloy was gradually abandoned. This method of transportation was completely banned after the collapse of the Soviet Union. The corresponding law was adopted in the Russian Federation on October 18, 1995 as part of the establishment of a new Water Code.
What is curious, as long as trees are rafted along the rivers, the number of fish in the reservoirs increases. Apparently, river inhabitants actively feed from logs floating and sinking in the water from time to time. Local residents of villages located near the rivers, where they used to be engaged in timber rafting, now and then note a decrease in the number of fish after the cessation of transportation.
