Tree breeding is the application of genetic, reproductive biology and economics principles to the genetic improvement and management of forest trees. In contrast to the selective breeding of livestock, arable crops, and horticultural flowers over the last few centuries, the breeding of trees, with the exception of fruit trees, is a relatively recent occurrence.
Forestry research with Human Resource Development in areas like biodiversity conservation, forest protection, silviculture, non-wood forest products, socio economics and tree improvement for poverty alleviation. The main stake holders for training programmes are farmer, students, Forest officers and scientist from forestry sector.
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 ...
The term continuous cover forestry has been widely adopted in British forestry practice following the creation of the Continuous Cover Forestry Group in 1991. It is also a widely used term in Ireland where continuous cover forestry is actively supported by a dedicated woodland improvement programme administered by the Department of Agriculture, Food and the Marine (DAFM).

Generally, silviculture is the science and art of growing and cultivating forest crops based on a knowledge of silvics, the study of the life history and general characteristics of forest trees and stands, with reference to local/regional factors. [2] The focus of silviculture is the control, establishment and management of forest stands.
A review of studies in British Columbia and in similar forest types indicates that while both aggregated and dispersed retention can contribute to biodiversity conservation there may be some negative consequences for timber production such as wind damage to retained trees and reduced growth rates of tree regeneration compared to clearcuts ...
The college has facilities for teaching undergraduate and post graduate degree programs, viz. Biodiversity Park on 50 ha, containing more than 150 plant species, Mist chamber and Nursery unit, which produces around 1 lakh seedlings of 50 tree species and several MAP species, Block Plantation of different timber tree species and multipurpose tree species, Bamboo museum having collection of 19 ...
In forestry, periodic annual increment (PAI) is the change in the size of a tree between the beginning and ending of a growth period, divided by the number of years that was designated as the growing period. [1] For sigmoid growth, the graph of PAI increases rapidly and then quickly declines, approaching zero. PAI may go negative if a tree ...
