Woodland biodiversity, palaeo-human ecology and some implications for conservation management

This paper appraises the role of prehistoric human societies in modifying t he natural woodland biodiversity of several regions throughout Scotland. It draws attention to the likelihood that, contrary to popular belief, biodiv ersity was enhanced by interactions between agricultural communities and wo odlands. The possible purposefulness of such interactions is discussed. Mindful of the present concern to re-establish 'native' woodlands in many p arts of northern Britain, we then review three approaches to the identifica tion of native tree types in Scotland, and conclude that insufficient atten tion in reafforestation schemes is being paid to (a) the palaeoecological r ecord as a record of native woodland or (b) the likely former high taxonomi c diversity of woodlands. Both these failings will lead to the creation of new woodlands lacking in species diversity.
