Classification type Classes Method Data sources

Land cover natural (forest, barrens, beaches) GIS reclassified Forestry Forestry GIS Database (NSDNR 1992 public communications)
  semi-natural (clear cut, plantation) GIS Database into land cover classes; areas of natural cover were selected out as priority areas
  degraded (agriculture, landfill)
  unnatural (built-up, urban)
  water
  unclassified
       
Area of contiguous natural cover 0–200ha GIS selected areas of natural cover that connect directly or by by-passing unnatural areas; selection ended when further connections could not be found; areas of natural cover greater than 10,000 ha were selected out as priority areas Forestry GIS Database (NSDNR 1992 public communications)
  200–2000ha
  2000–10,000 ha
  greater than 10,000 ha
       
Road density 0 km/km2 GIS calculated total length of road (major and secondary roads, trails, railways, cart tracks, and woods roads) in each 1-km square grid cell; areas of zero road density (no roads) were selected out as priority areas Provincial aerial photographs taken between 1987 and 1997 and mapped at a scale of 1:10,000 by NS Geomatics Centre
  0.01–0.06 km/km2
  0.06–0.60 km/km2
  0.60–1.0 km/km2
  1.0–3.0 km/km2
  greater than 3.0 km/km2
       
Forest cover maturity regeneration GIS reclassified Forestry Forestry GIS Database (NSDNR 1992 public communications)
  young GIS Database into maturity classes; uneven-aged stands were selected out as priority areas
  immature
  pole
  mature
  over mature
  uneven aged

 

   Note: All classifications were processed as UTM NAD83 projections with ArcInfo 8.01.
