Second one, species selection for timber forest should consider growth speed, yield, timber quality and forest stability. Last one is the methods of fitting species to the site include selection and modification, but selection is more important, more basic one.<\/p>\n See online APFNet Course 6: Forest Resource Management and Protection (http:\/\/blogs.ubc.ca\/apfnet06\/<\/a>) Module I, Topic 1 Principles of silviculture, 1.1.2 Species selection.
