Sustainable forestry Timber is a renewable resource with a sustainable yield. Sustainable forestry takes into consideration the varied roles of woodland: ;It is a valuable source of timber (for building sector) ;It provides habitats for wildlife ;Important in sustaining biodiversity ;Important role in recreation and leisure activities Trees removed for timber may be replaced with young tress so that the woodland is regenerated 0 The following factors may be considered:
Softwood species (Sites spruce,lodged pine and larch) are frequently planted since they have relatively high yields and so generate more timber. Management of timber prod auction is more considerable and alternative systems to clear-felling (large areas of woodland cut down at the same time) are used. Copping (management based on regeneration by Rexroth from the cut stumps) can be used for some hardwood species, such as willow, hazel and ash, and causes least disruption on the forest ecosystem. Et aside’ land schemes’ This scheme is set to encourage land owners / farmers to allow areas of land previously used for food production to return to nature by planting trees. E. G. At field margins or small areas of isolated land. New plantings create a range of habitats that further encourage diversity and improve the aesthetic appeal Of the forested countryside. Soft wood forests advantages Soft wood forests egg, larch and spruce grow more quickly.
Able to grow in poor soil conditions (less fertile and more acidic soil)- enables immemorial woodland to be sited in areas not particularly suitable for intensive agriculture. Disadvantages The high density of softwood forest planting decreases diversity. Hard wood forest Advantages Indigenous hardwood forests, egg ash and oak provides greater variety of habitats and increased biodiversity com pared to introduced larch and spruce. Decomposition of leaves provide soil with nutrients Hardwood species are very site specific. Particular sites need to be identified before planting or seeding.
