Quality in reforestation: an approach from silviculture and ecophysiology

Abstract

The forest regeneration process is complex because successful regeneration requires combining an understanding of physiological performance and morphological development characteristics of Mediterranean species with proper silvicultural practices. Ultimately, seedling performance on a reforestation site depends on the inherent growth potential of the seedlings and the degree to which field site environment conditions limit or enhance this potential. Nursery cultural and pre planting silvicultural practices have a strong influence on seedling performance immediately after planting. The effects of these practices on seedling performance need to be understood to make sound forest regeneration decision. The intent is to try and define factors that can enhance as well as limit the development of seedlings on reforestation sites. Seedling performance is examined in relation to possible site limiting environmental conditions and silvicultural practices (e.g. site preparation, vegetation management, pos-planting practices, etc.) that can possibly mitigate these environmental constraints and improve seedling performance.
