Land cover and land use, Sherbrooke census metropolitan area (CMA) and census metropolitan area-ecosystem (CMA-E), 1971, 1991, 2001 and 2011
Table summary
This table displays the different types of land cover and land use for Sherbrooke. The row headers provide information on the total land area, total built-up which is further split into settled and roads, arable and natural and semi natural lands, in 1971, 1991, 2001, and 2011. In 2011, the natural category is further split into forest, water and other. The row headers also provide information on the land cover and land use change from 1971 to 2011 for total built-up, arable, and natural and semi natural. The column headers provide information on area, in square kilometres, and percentage change for the CMA, and CMA-ecosystem. The column headers also provide information on CMA as a proportion of CMA-ecosystem as a percentage.

Note 1.

2011 census metropolitan area (CMA) boundaries are used for all years. Total area excludes water.

Note 2.

The CMA-Ecosystem (CMA-E) combines any Soil Landscapes of Canada (SLC) polygon that is contained within or that intersects with the CMA boundary, as well as SLC polygons that are fully contained within this newly formed boundary of the CMA-E. Includes all terrestrial and water surfaces.

Note 3.

Built-up area for 1971 is based on Canada Land Inventory: Land Use (CLI: LU), code B – Urban Built-up. Canada Land Use Monitoring Program (CLUMP) data exclude the CMAs of Moncton, Trois-Rivières, Sherbrooke, Peterborough, Kingston, Barrie, Brantford, Kelowna and Abbotsford–Mission. As a result, 1971 built-up areas may be underestimated for these CMAs. CLI: LU built-up areas that were not built-up in the AAFC Land Use, 1990 dataset were removed from the 1971 built-up data and reclassified according to their 1990 cover. To improve comparability with the other years, roads included in the core built-up area were identified and removed to produce the 1971 settled area. The 1971 dataset did not include roads outside the core built-up area. Roads were modeled by applying the ratio of roads to settled area from 1990 to the 1971 settled area.

Note 4.

Arable land area is composed of the cropland, tame or seeded pasture and summerfallow land from the Interpolated Census of Agriculture.

Note 5.

Natural and semi-natural land is the residual area remaining after subtracting built-up and arable land from the total area. Because it was calculated residually, the class also includes some homes and other buildings, particularly those located on large lots and in rural areas, since these may not be captured by satellite imagery as built-up, due in part to the resolution of the data and overlying tree canopy.

Note 6.

Built-up area estimates for 1991, 2001 and 2011 are based on Land Use, 1990, 2000 and 2010, codes 21 (Settlement–Built-up and urban) and 25 (Roads–primary, secondary and tertiary).

Note 7.

For 2011, forest and water are broken out separately based on data from AAFC Crop Inventory, 2011 and CanVec+ respectively. Other natural and semi-natural land is a residual class calculated by subtracting all other classes from the total area. The change over time for these categories requires further validation.
