Ecological assessment of proposed road developments: a review of environmental statements

Abstract Since the adoption of EC Directive (85/337) in the UK in 1988, potential environmental impacts of certain proposed road schemes must be assessed before development consent can be given. This paper focuses specifically on the ecological effects of road developments. A review of Environmental Statements produced for road development schemes is described, and the methods used to assess ecological effects are summarized. Many statements failed to provide the data necessary to predict potential ecological impacts, and very few attempted to quantify these impacts. It is suggested that ecological assessments should be carried out earlier in the planning and design of new roads, thereby permitting more thorough assessments to be made.
