Felling made in immature stand for the purpose of improving the growth and form of the trees that remain without permanently breaking the canopy. It is mainly done:
Pollarding consists of cutting a sapling or pole tree at some height above the ground level so that it produces new shoots from below the cut. Pollarding is done at a height of 2- 2.5 m above ground level; e.g. in Salix spp., Hardwickia binata, Grewia optiva, Morus alba, etc.
Removal of one year shoots or fresh growth from entire crown of the tree/plant in order to get sufficient fodder for livestock is known as lopping. Lopping is extensively done in Morus, Grewia, Bauhinia, etc.
Cutting or heading back of main stem at 20-30 cm from the ground level. Strong coppicers: Acacia catechu, Albizia lebbek, Anogeissus latifolia, etc.; Good coppicers: Aesculus indica, Chloroxylon swietinia, Hardwickia binata, etc.; Bad coppicers: Adina cordifolia, Bambax ceiba, etc.; and Non coppicers: All conifers.
Restricting the development of bole to allow more food material to new leaf shoots. Bending and coppicing are useful when it is desirable to produce large quantity of foliage close to ground level.
In agroforestry vertical spread of the tree is a desirable feature, therefore trees raised in agroforestry systems must be vertically trained to avoid shade and light competition to underground crop.
