Global review of forests pests and diseases : a thematic study prepared in the framework of the Global forest resources assessment 2005 Rome : Food and Agriculture Organization of the United Nations, 2009 ix, 222 p. : col. ill., maps ; 30 cm Insect pests, diseases and other biotic agents have considerable impacts on forests. They can adversely affect tree growth, vigor and survival, the yield and quality of wood and non-wood products, wildlife habitat, recreation and the aesthetic appeal and cultural value of forests. They may also impede forest plantation programs and make it necessary to abandon certain tree species or to clear cut large areas dominated by infested trees. This publication represents an effort to address forest pests and diseases comprehensively at the global level. Part I summarizes the results of a thematic study reviewing forest pests in 25 countries. Part II presents profiles of some globally important forest pest species, and III discusses select forest trees species and their associated pests.--Publisher's description Trees Trees Forest surveys Food and Agriculture Organization of the United Nations http://www.fao.org/docrep/011/i0640e/i0640e00.htm EK 15680 15680 0 0 0 634_000000000000000_FOO_2009_A091_OR 0 69288 LBA LBA A091 2017-12-05 634 FOO 2009 A091 Or.
