List of figures

  • Figure 1. Critical habitat for Dun Skipper vestris subspecies at van Home Creek (Population 3; 329.6 ha), Koksilah River (Population 12; 329.6 ha), and west of Shawnigan Lake (Population 9; 329.6 ha), B.C. is represented by the yellow shaded polygons (units) where the criteria and methodology set out in Section 1.1 are met. The 1 km x 1 km UTM grid overlay shown on this figure is a standardized national grid system that indicates the general geographic area within which critical habitat is found in Canada. Areas outside of the shaded yellow polygons do not contain critical habitat.
  • Figure 2. Critical habitat for Dun Skipper vestris subspecies at Nanaimo River (Population 6; 682.0 ha) and Big Sicker Mountain (Population 10; 329.6 ha), B.C. is represented by the yellow shaded polygons (units) where the criteria and methodology set out in Section 1.1 are met. The 1 km x 1 km UTM grid overlay shown on this figure is a standardized national grid system that indicates the general geographic area within which critical habitat is found in Canada. Areas outside of the shaded yellow polygons do not contain critical habitat.
  • Figure 3. Critical habitat for Dun Skipper vestris subspecies northeast of Port Alberni (Population 7; 434.7 ha), at Denman Island (Population 18; 739.2 ha), and at Hornby Island (Population 21; 129.1 ha), B.C. is represented by the yellow shaded polygons (units) where the criteria and methodology set out in Section 1.1 are met. The 1 km x 1 km UTM grid overlay shown on this figure is a standardized national grid system that indicates the general geographic within which critical habitat is found in Canada. Areas outside of the shaded yellow polygons do not contain critical habitat.
  • Figure 4. Critical habitat for Dun Skipper vestris subspecies at Mount Currie (Population 8; 329.6 ha), Blackwater Creek (Population 26; 329.6 ha), and Railroad Creek (Population 27; 329.6 ha), B.C. is represented by the yellow shaded polygons (units) where the criteria and methodology set out in Section 1.1 are met. The 1 km x 1 km UTM grid overlay shown on this figure is a standardized national grid system that indicates the general geographic area within which critical habitat is found in Canada. Areas outside of the shaded yellow polygons do not contain critical habitat
  • Figure 5. Critical habitat for Dun Skipper vestris subspecies south of Lytton (Population 25; 724.0 ha) and at Boston Bar (Population 16; 3063.7 ha), B.C. is represented by the yellow shaded polygons (units) where the criteria and methodology set out in Section 1.1 are met. The 1 km x 1 km UTM grid overlay shown on this figure is a standardized national grid system that indicates the general geographic area within which critical habitat is found in Canada. Areas outside of the shaded yellow polygons do not contain critical habitat.
  • Figure 6. Critical habitat for Dun Skipper vestris subspecies at Dog Mountain (Population 17; 664.9 ha) and at Yale (Population 24; 329.6 ha), B.C. is represented by the yellow shaded polygons (units) where the criteria and methodology set out in Section 1.1 are met. The 1 km x 1 km UTM grid overlay shown on this figure is a standardized national grid system that indicates the general geographic area within which critical habitat is found in Canada. Areas outside of the shaded yellow polygons do not contain critical habitat.
  • Figure 7. Critical habitat for Dun Skipper vestris subspecies at Saltspring Island (Population 19; 666.0 ha), B.C. is represented by the yellow shaded polygons (units) where the criteria and methodology set out in Section 1.1 are met. The 1 km x 1 km UTM grid overlay shown on this figure is a standardized national grid system that indicates the general geographic area within which critical habitat is found in Canada. Areas outside of the shaded yellow polygons do not contain critical habitat.
  • Figure 8. Critical habitat for Dun Skipper vestris subspecies at Burns Bog (Population 20; 454.3 ha), B.C. is represented by the yellow shaded polygons (units) where the criteria and methodology set out in Section 1.1 are met. The 1 km x 1 km UTM grid overlay shown on this figure is a standardized national grid system that indicates the general geographic area within which critical habitat is found in Canada. Areas outside of the shaded yellow polygons do not contain critical habitat.
  • Figure 9. Critical habitat for Dun Skipper vestris subspecies west of Morris Lake (Population 22; 659.2 ha) and at Soowahlie Indian Reserve 14 (Population 23; 329.6 ha), B.C. is represented by the yellow shaded polygons (units) where the criteria and methodology set out in Section 1.1 are met. The 1 km x 1 km UTM grid overlay shown on this figure is a standardized national grid system that indicates the general geographic area within which critical habitat is found in Canada. Areas outside of the shaded yellow polygons do not contain critical habitat.
