| Summary: | <p>The aim of this publication is to assist foresters in the selection of species for inclusion in the initial phase of forest species trials programmes. The intention is not to recommend particular species for specific site or climatic conditions, or plantation objectives. Given the varying tolerance and adaptability of different species, and the imprecise methods of quantifying site factors and their interactions, such final selection can only be based on first hand experience of species' performance under any given set of site conditions. Such experience can only be gained by the establishment of species trials. Whilst the degree of sophistication and duration of trials programmes may vary, the need for some form of trials before embarking on large scale planting programmes cannot be overemphasized...</p>
