Table of contents - part 1

List of tables

  • Table 1. Activities likely to result in the destruction of critical habitat for Edwards’ Beach Moth. IUCN Threat numbers are in accordance with the IUCN-CMP (World Conservation Union–Conservation Measures Partnership) unified threats classification system (CMP 2010).

List of figures

  • Figure 1. Critical habitat for Edwards’ Beach Moth on Sidney Island, B.C. is represented by the yellow shaded polygons where the criteria and methodology set out in Section 2.1 are met. The detailed polygons show a total of 35.4 ha containing critical habitat at Sidney Spit (3.7 ha) and Hook Spit (31.7 ha). 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 Edwards’ Beach Moth on James Island and on southeast Vancouver Island, B.C. is represented by the yellow shaded polygons where the criteria and methodology set out in Section 2.1 are met. The detailed polygons show a total of 21.2 ha containing critical habitat on James Island at Powder Jetty (7.0 ha), North Spit (8.7 ha), and Melanie Spit (5.5 ha), and 30.0 ha on southeast Vancouver Island, at Cordova Spit & Island View Beach. 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 Edwards’ Beach Moth at Wickanninish Beach near Tofino, B.C. is represented by the yellow shaded polygons where the criteria and methodology set out in Section 2.1 are met. The detailed polygon shows a total of 30.0 ha containing critical habitat at this site. 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.
