Tandem-rotor helicopter lifting a log Helicopter pruning. Heli-logging, or helicopter logging, is a method of logging that uses helicopters to remove cut trees from forests by lifting them on cables attached to a helicopter. [1] Helicopter logging is often used in inaccessible areas of forests. Because the use of helicopters reduces the level ...
Cut-to-length logging (CTL) is a mechanized harvesting system in which trees are delimbed and cut to length directly at the stump. [1] CTL is typically a two-man, two-machine operation with a harvester felling, delimbing, and bucking trees and a forwarder transporting the logs from the felling to a landing area close to a road accessible by ...
Sustainable forestry – providing for the needs of society in the form of forest products while maintaining the health of forests and their mitigation of climate change and biodiversity loss through forestry practices that mimic natural patterns of disturbance and regeneration, such as balancing the numbers of trees by age, to provide a ...
Options for cutting off the branches include chain saws, harvesters, stroke delimbers and others. Limbing can happen at the stump in log/tree length systems and cut-to-length systems or at the landing in whole-tree logging. Chainsaw limbing. When the tree is lying on the ground, branches may be storing enormous potential energy through ...
Forests or tree plantations, those whose primary purpose is the extraction of forest products, are planned and managed to utilize a mix of ecological and agroecological principles. [11] In many regions of the world there is considerable conflict between forest practices and other societal priorities such as water quality, watershed preservation ...
A harvester is a type of heavy forestry vehicle employed in cut-to-length logging operations for felling, delimbing and bucking trees. A forest harvester is typically employed together with a skidder that hauls the logs to a roadside landing, for a forwarder to pick up and haul away. CAT 501 HD with tracked treads
More recently, forest managers have found that clearcutting oak stands helps regenerate oak forests in areas of poor soil. The tree canopies in oak forests often shade out the ground, making it impossible for newly sprouted oaks to grow. When the mature trees are removed, the saplings stand a chance of recruiting into the forest. [30]
Mt. Otzi Forest Reserve was established because of its rich biodiversity, but over the years it has been affected by anthropogenic and natural disturbances. The Forest Reserve's tree species distribution was significantly affected by altitude, fire, farm lands, fallow, and felling by cutting, according to Canonical Correspondence Analysis (CCA ...
