Conservation Status Ranks

The Conservation Data Centre (CDC) assesses the level that B.C. species or ecological communities are at risk of being lost. Based on that, the CDC assigns a provincial Conservation Status Rank that can be used to set conservation priorities.

BC Species & Ecosystem Explorer search results display the following provincial Conservation Status Rankings. The year the status was last reviewed appears in parenthesis after the ranking code. The prefix on the code indicates the geographic level at which the rank is applied – subnational (provincial), national or global.

Type of rank Meaning
S Subnational ranks assigned and maintained by the B.C. Conservation Data Centre
N National ranks assigned by national and international conservation authorities
G Global ranks assigned by national and international conservation authorities
