The Significance of Forests

Introduction Forests can shape our landscape; they provide a very precious appeal for rural areas and suburban areas to determine the characteristic landscape features. In addition, the importance of interpretation of design can promote management objectives and results, especially near populated areas. Among them, the community has fear of affinity, vested interest, general profit, or change. Historical landscape design: The main influence on the forest landscape is the establishment of the Forestry Act and the Forestry Commission (FC) in 1919 and its role is to establish strategic wood reserves necessary for war.

After many of the farms were abandoned after the liberation, the forest area in the mid - 19th century increased significantly. It is estimated that by 1886 it increased to 323,760 hectares. By the end of the century, the increase in banana cultivation resulted in more land felling, which also resulted in a reduction in forest area. By 1943 the forest area declined 32% to 219,230 hectares, or about 0.57% annually. Nevertheless, in 1943, about 20% of the Jamaican people were covered with forests. The first systematic land cover research in Jamaica was completed in 1968 - it was published by Gray and Sims in 1972. They decided that Jamaica has a total of 491,252 hectares of 260,869 hectares of natural forests, 4,131 hectares of forest plantations and 226,252 hectares of other forests. This brought about an important and complex factor to the discussion: "What is forest covering?"

Forests are essential to Portugal because one third of Portugal is covered with forests. 83% of all forests are private, most of which are included in farmland. Given its importance, there has been a strategic change in the public management of forests in recent years to provide more and better services to private forests. The public forest area is 519,000 hectares, basically composed of coniferous forests. 3% is state-owned and is mainly composed of pine tree (Pinus pinaster). These are dominant in coastal areas and are subject to management plans to ensure the sustainable production of high quality timber. One quarter of the forest covers the coastal sand dunes. The harvest is managed by the conservation guidelines and ensures regeneration through clear logging. 6% of forests are managed by industrial enterprises (pulp industry)

Plantation accounts for only 7% of the world's forest area, but occupies more than half of the world's industrial log production (FAO, 2006b). There is a high possibility of expanding plantations to land that is free from limits of land and crops and livestock production. The proportion of sustainable industrial logs and timber used for power generation is increased by afforestation rather than native forest. Inefficient use of water for irrigation leads to poor energy efficiency, so it is expected that improvement of irrigation efficiency will lead to energy saving and reduction of pumping cost. Protective agriculture saves about 60% of diesel fuel over the whole planting cycle compared to traditional agriculture. Reducing the fuel demand for primary and secondary farming work and planting is particularly important. Use other inputs that require energy, such as machinery, chemical fertilizers, agricultural chemicals.
