Most landscape definitions in the western world are based on soil, climatic, or physiographic features and do not integrate
humans as an integral part of the landscape. We present an approach where landscape types have been delineated in southern
Québec, Canada based on current land use where anthropogenic and agricultural activities are concentrated as a practical application
of the holistic approach in landscape definition. Landsat-TM satellite images were classified and the 27 habitat classes were
regrouped into 5 general land cover classes (cash crop, dairy farming, forest, anthropogenic, wetlands) and overlaid onto
soil landscape polygons to characterize natural boundary units. Cluster analyses were used to aggregate these polygons into
seven agricultural types of land scape forming a gradient from urban and high-intensity cash crop farming activities to landscapes
dominated by a mosaic of agriculture and forested areas. Multivariate analyses of raw data and of socio-economic and farming
practices variables were used to describe the defined types of landscape and these were projected over three established land
classification systems of southern Québec (Canadian ecoregions, North American Bird Conservation Initiative regions and Corn
Heat Unit regions) to compare their similarity in terms of land cover and for planning of future ecological studies. Because
agricultural landscapes are highly dynamic, they are bound to undergo changes in the near future. Our landscape delineation
may serve as an experimental setup where land scape dynamics and wildlife populations and community structures could be monitored.
Because the information we used to delineate and characterize agricultural landscape types is readily available in other countries,
our approach could easily be adapted to similar data sources under and a wide variety of landscape types.
