Appendix C. Classes for assessing site potential for representation.
|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)|
|Area of contiguous natural cover||0200ha||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)|
|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|
|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|
Note: All classifications were processed as UTM NAD83 projections with ArcInfo 8.01.
