Compile Lists of Species and Ecological Communities 
(Elements)
Element: A recognized classification (taxa) of plant, animal or ecological community 
(the biological unit that we track in BC)
View provincial lists of elements through BC Species and Ecosystems Explorer (BCSEE):
•Vertebrates
•Invertebrates
•Vascular Plants
•Bryophytes (Mosses, Liverworts and Hornworts)
•Lichens
•Macrofungi
•Ecological communities
Currently over 24,000 elements reported through BCSEE!
Refer to BCSEE for the standard scientific and common names in B.C.

BC Conservation Status Ranks
range ranks/uncertainty
(e.g.S1S2, S2?)
SNR +
global ranks (G Ranks) and 
national ranks (N Ranks)
S1 – Critically Imperiled
S2 – Imperiled
S3 - Vulnerable
S4 – Apparently Secure
S5 - Secure

Simplified groupings of conservation status ranks.
Non-regulatory!
Red List: SI (critically imperiled), S2 (imperiled), SH (possibly extirpated), SX (presumed extirpated)
Blue List: S3 (vulnerable)
Yellow List: S4 (apparently secure) or S5 (secure)
