Technical Data Report Vegetation ENBRIDGE NORTHERN GATEWAY PROJECT AMEC EARTH & ENVIRONMENTAL A division of AMEC Americas Limited Calgary, Alberta David E. Reid, M.Sc., P. Biol. Carol E. Thompson, B.Sc. Mary Ann Johnson, B.Sc., P. Biol. Laura C. Roberts, M.Sc., P. Biol. 2010 Preface This technical data report (TDR) relies primarily on data collected up to September 2008. These data are used in the vegetation environmental and socio-economic assessment (ESA) for the Enbridge Northern Gateway Project, Volume 6A Part 1, Section 8, which also includes more recent data collected up to June 2009. Some minor discrepancies may occur between this TDR and the ESA because of the different datasets.
