Management restores health to forests in several ways. Logging opens up the ecosystem for new plant growth. Removal of litter reduces the intensity of future fires by decreasing the fuel load so that devastating crown fires that kill all plant life in their path can be avoided.
Logging favors the succession of plants that are adapted to an ecosystem, often getting rid of non-native species which may take over a habitat.
Habitats where fire is frequent include species adapted to its presence. For example, jack pine relies on fire to prompt its cones to open. Non-native grasses like brome are not adapted to fire and will perish. If managed improperly, logging can have serious environmental impacts. Logging potentially removes habitat for birds and other wildlife that use trees for cover, nesting habitat, or food.
Owls, for example, prefer older trees with a larger diameter for nest cavities. If logging occurs along stream banks, the risk of flooding and erosion increases, as these trees help to anchor the soil in place Erosion also occurs through the logging operation itself.
What follows is a rushed effort to maximize yield and profit as fast as possible. Little consideration is given to safeguard timber stocks for future harvests, and this leads to the usual litany of biodiversity loss, over-hunting of wildlife and subsequent conversion for agriculture or pasture.
Collateral damage Although selected logging targets specific commercially valuable trees, logging methods usually result in collateral damage. Surrounding trees may be damaged or brought down unintentionally. IMAZON Amazon Institute of Man and the Environment has documented that for every commercial tree removed, 27 other trees more than 10 cm in diameter are damaged, 40 m of road are created and m 2 of canopy is opened 4.
Once fallen, trees must be transported which may involve using tractors. The erosion that follows logging washes away nutrients and adversely affects streams and rivers.
It also takes time for timber to grow back, provided that the logged areas have not been taken over for cattle-ranching or cultivation. Do forests grow back on logged areas? Loss of trees adjacent to streams can increase water temperatures. Related Stories. That is a key finding of a new The findings In the wake of the And researchers Spiders' Web Secrets Unraveled. Using a novel technique, researchers have been able Generally, a high school diploma is sufficient for most logging occupations.
Through on-the-job training, logging workers become familiar with the character and dangers of the forest environment and the operation of logging machinery and equipment. However, many loggers also undergo additional training provided by their state agencies or local logging companies and trade associations. Many states have training programs for loggers, which included classroom or field training in areas such as best management practices , environmental compliance, wetlands, safety, endangered species, reforestation, and business management.
Some programs lead to logger certification.
