Saskatoon, Sask. : Canadian Wildlife Service, Prairie and Northern Region, 2002. iv, 23 p. : ill. (some col.) Canadian Wildlife Service technical report series ; no. 384 Digitized edition [produced by Environment and Climate Change Canada]. Includes bibliographical references (p. 14). "The land classification scheme for St. Denis National Wildlife Area (NWA) was updated using a 1: 2500 orthographically corrected photomap, which was based on aerial photography obtained October 1997. ... The land classification scheme was generated in a Geographic Information System (GIS) by identifying and digitizing seven vegetation and land use categories: ponds, wetland vegetation, trees/shrubs. native grassland, tame grassland, cultivated land and farm/rights-of-way. This report outlines the methods of map creation along with an analysis of the area of each land use category and overall accuracy of the map based on ground checking. References are made to hydrological and land use data sources for the NWA. A comparison is made to a previous land classification based on 1983 aerial photography. Identification of hydrological impacts on the wetlands from seeding cultivated land with planted grass cover at the NWA has also highlighted the necessity of documenting the spatial and temporal extent of these land use changes. This report provides a summary of significant land use changes since the site was established as well as information on recent cropping and agricultural land management practices"--Abstract, p. i.
