What is called log?
logarithm, the exponent or power to which a base must be raised to yield a given number. Expressed mathematically, x is the logarithm of n to the base b if bx = n, in which case one writes x = logb n. For example, 23 = 8; therefore, 3 is the logarithm of 8 to base 2, or 3 = log2 8.

A logarithm is the power to which a number must be raised in order to get some other number (see Section 3 of this Math Review for more about exponents). For example, the base ten logarithm of 100 is 2, because ten raised to the power of two is 100: log 100 = 2. because. 102 = 100.

How does strip logging work?
Strip logging involves the clear-cutting of a relatively thin strip of forest that parallels a river (goes along the river) along a slope. A gallery forest (bordering the river) is left intact, but a strip is cut immediately upslope and the desirable timber is removed by a road that is also designed to parallel the river. Following this, another strip is cut several years later immediately upslope to the first strip and the road. Nutrients eroded (broken down) from the newly cut strip wash down slope and aid in spreading the recovery of the first strip (Kricher, 1997, p. 346). The process allows the strip to regenerate (regrow) while selecting another strip upslope. It also prevents erosion (the wearing down of nutrients from the soil) because the strip is buffered by a row of trees remaining and a supply of nutrients from the newly cut strip. Smart, huh?
How does selective logging affect trees?
This is a very interesting question! You think it would be, but actually selective logging can be very damaging to the surrounding trees which are not selected for logging. What happens is that the heavy equipment used to cut the selected trees often damages the surrounding trees. It is estimated that 40% (40 out of 100 trees) die from just one tree that is selectively logged (Kricher, 1997). That's a lot of damage!
What is logging in paper?
By Lisa Algee. Logging, or commercial logging, involves cutting trees for sale as timber or pulp. The timber is used to build homes, furniture, etc and the pulp is used to make paper and paper products. Logging is generally categorized into two categories: selective and clear-cutting. Selective logging is selective because loggers choose only wood ...
Why is selective logging considered selective?
Selective logging is selective because loggers choose only wood that is highly valued, such as mahogany. Clear-cutting is not selective. Loggers are interested in all types of wood and therefore cut all of the trees down, thus clearing the forest, hence the name- clear-cutting.
Why is the strip buffered?
It also prevents erosion (the wearing down of nutrients from the soil) because the strip is buffered by a row of trees remaining and a supply of nutrients from the newly cut strip.
Why is clear cutting harmful to tropical rainforests?
According to NASA, clear cutting is much more damaging to a tropical rain forest because when all of the trees are removed, the soil loses its nutrients and becomes barren (NASA, 1998).
How do trees help the soil?
Flooding. Trees keep the soil stable by absorbing rain water. Rainforests receive 1,500-3,000 mm of water annually (hmmm, how many inches is that?) That's a lot of water! Without trees, flooding and mud-slides can occur causing serious environmental and ecomonic damage. Seedlings (young plants) and existing trees can be wiped out as well as nearby homes and buildings. Many people have lost their lives due to massive floods and land slides.
