Notes:
1) For caribou, increasing, Stable, Declining and Extirpated do
not add up to total historic area, because there are several caribou
sub-populations for which the status is unknown (accounting for
approx. 114,000 km2), as well as an additional approx.
154,000 km2 where caribou occur sporadically.
2) Extirpated includes 9,094km2 on the Queen Charlotte
Islands that was the range of the Dawson Caribou subspecies, extinct
since 1910.
3) For Grizzly Bears, "Threatened" includes both Poor
and Fair population viability classes.
4) Extirpated includes areas that are not Viable.
