Question

write any two suggestions for in improvement of forest coverege​

Answer 1

In regulated cutting only one-tenth of the forest area is selected for use and rotational system is always followed for their protection.

Answer 2

Answer:

Control over Forest Fire

Destruction or loss of forest by fire is fairly common; because trees are highly exposed to fire and once started it becomes difficult to control. Sometimes, the fire starts by natural process, i.e., by lightning or by friction between trees during speedy winds, while in most cases it is also by man either intentionally or uninten­tionally.

According to an estimate, during the period from 1940 to 1950, in the US alone, fires consumed an average of 21.5 million acres of timber yearly and as many as 1,175,664 cases of forest fires occurred during 1955 to 1964 period. In US forests fire is very common and a main cause of the loss of forest.

Throughout the world forest fire is common and in most cases they were begun by man. As John D. Guthrie, former fire inspector of US Forest Service has written: “To stage a forest fire you need only few things a forest, the right atmospheric conditions, and a spark either from a lightning bolt or a match in the hands of a fool or a knave. The formula is simple the larger the forest, the drier the air, the bigger the fool, the bigger the fire you will have.”

In order to save forests from fire, it is necessary to adopt latest techniques of fire fighting. Some of the fire suppression techniques are to develop three metre wide fire lanes around the periphery of the fire, back fires, arrangement of water spray, fire retardant chemicals should be sprayed from back tank and if possible by helicopters. There must be trained staff of fire fighters to control the fire.

Reforestation and Afforestation

The sustained yield concept dictates that whenever timber is removed, either by block cutting or by selective cutting, the denuded area must be reforested. This may be done by natural or artificial methods. Similarly, any forested land, which has been destroyed by fire or mining activities, should be reforested. In rugged terrain aerial seeding is the method of choice.

Besides all this, fresh afforestation programmers should be started. New plantations will not only increase the forest cover but also help in making up the eco-balance. For afforestation, selection of trees should be done according to local geographical conditions and care must be taken during initial growth of the trees.
