Abstract

There is renewed interest in planting mixed-species stands for the purpose of improving wood quality characteristics. The underlying premise is that mixed-species stands will have some of the advantages of growing trees at higher densities, without the disadvantage of increased competitive mortality. We undertook to search the literature for information that would either support or weaken this assumption. We knew from previous searches that there are few, if any, studies that address this subject directly. This literature review was done in conjunction with the establishment of high density mixed-species plots to directly investigate the subject. In this literature review we first consider what are the characteristics of wood quality and how they are influenced by growing conditions. Then we consider mixed-species stand growth and development pointing out the similarities and differences with single-species stands. We conclude with the implications and likely outcomes of growth in mixed species-stands on wood quality.
