List of Figures

• Figure 1. Critical habitat for the Blue-grey Taildropper at Matheson Lake, Devonian, and Rocky Point, B.C. is represented by the yellow shaded polygons (units), in accordance with the criteria and methodology set out in section 2.1. The 1 km x 1 km standardized UTM grid overlay shown on this figure is part of a standardized national grid system that indicates the general geographic area within which critical habitat is found. Areas outside the shaded yellow polygons do not contain critical habitat.
• Figure 2. Critical habitat for the Blue-grey Taildropper at Galloping Goose, B.C. is represented by the yellow shaded polygon (unit), in accordance with the criteria and methodology set out in section 2.1. The 1 km x 1 km standardized UTM grid overlay shown on this figure is part of a standardized national grid system that indicates the general geographic area within which critical habitat is found. Areas outside the shaded yellow polygons do not contain critical habitat.
• Figure 3. Critical habitat for the Blue-grey Taildropper at Sooke Hills, B.C. is represented by the yellow shaded polygon (unit), in accordance with the criteria and methodology set out in section 2.1. The 1 km x 1 km standardized UTM grid overlay shown on this figure is part of a standardized national grid system that indicates the general geographic area within which critical habitat is found. Areas outside the shaded yellow polygons do not contain critical habitat.
• Figure 4. Critical habitat for the Blue-grey Taildropper at Logan, Prior Lake, Thetis Lake, and Mill Hill-Colwood, B.C. is represented by the yellow shaded polygons (units), in accordance with the criteria and methodology set out in section 2.1. The 1 km x 1 km standardized UTM grid overlay shown on this figure is part of a standardized national grid system that indicates the general geographic area within which critical habitat is found. Areas outside the shaded yellow polygons do not contain critical habitat.
• Figure 5. Critical habitat for the Blue-grey Taildropper at Observatory Hill, B.C. is represented by the yellow shaded polygons (unit), in accordance with the criteria and methodology set out in section 2.1. The 1 km x 1 km standardized UTM grid overlay shown on this figure is part of a standardized national grid system that indicates the general geographic area within which critical habitat is found. Areas outside the shaded yellow polygons do not contain critical habitat.
• Figure 6. Critical habitat for the Blue-grey Taildropper at Durrance Lake, B.C. is represented by the yellow shadedpolygon (unit), in accordance with the criteria and methodology set out in section 2.1. The 1 km x 1 km standardized UTM grid overlay shown on this figure is part of a standardized national grid system that indicates the general geographic area within which critical habitat is found. Areas outside the shaded yellow polygons do not contain critical habitat.
• Figure 7. Critical habitat for the Blue-grey Taildropper at Mt. Tzouhalem, B.C. is represented by the yellow shaded polygon (unit), in accordance with the criteria and methodology set out in section 2.1. The 1 km x 1 km standardized UTM grid overlay shown on this figure is part of a standardized national grid system that indicates the general geographic area within which critical habitat is found. Areas outside the shaded yellow polygons do not contain critical habitat.
