Document Summary
Deforestaion rates: esimated loss of 1 billion hectares of forested land, most of this loss occurred in temperate laitudes, more recently, losses in temperate laitudes reduced, accelerated deforestaion in tropical regions. Crown cover: when sun is on top and shine down on loor: closed forests: at least 20% crown cover, open forests: 5-20% crown cover. Dominant forest harvesing pracice that has caused signiicant conlict in. Enire stands of trees are felled and removed. Harvest of selected trees of various ages in a stand. Valuable, mature trees, along with poorly shaped, unhealthy, crooked, damaged trees selected. Coninuous and regular supply of mature trees over ime. Diiculty in deining deforestaion rates: complete clearance of forests for agriculture and other land uses, reducing crown cover to less than 10, degraded forests vs. deforestaion. Deforestaion and forest management pracices have an impact on both the risk and impacts of hazardous events.
