Dendrology
Dendrology ( grc, δένδρον, ''dendron'', "tree"; and grc, -λογία, ''-logia'', ''science of'' or ''study of'') or xylology ( grc, ξύλον, ''ksulon'', "wood") is the science and study of woody plants ( trees, shrubs, and lianas), specifically, their taxonomic classifications. There is no sharp boundary between plant taxonomy and dendrology; woody plants not only belong to many different plant families, but these families may be made up of both woody and non-woody members. Some families include only a few woody species. Dendrology, as a discipline of industrial forestry, tends to focus on identification of economically useful woody plants and their taxonomic interrelationships. As an academic course of study, dendrology will include all woody plants, native and non-native, that occur in a region. A related discipline is the study of sylvics, which focuses on the autecology of genera and species. Relationship with botany Dendrology is a branch of botany th ...
