Table IV-4. Abundance, precision, trend, and
recovery factors for
endangered species and Cook Inlet beluga. (The end point for use in the
decision tree in Figure IV-2 is in italics if a change would be required, and
has an asterisk if a change may be required depending on the increase in recovery
time chosen for the different risk levels. Note that the only case where
choice of the threshold criterion makes a difference -- see Tables IV-1 and IV-2
-- is for the central North Pacific humpback whale, but that both end points
I and J result in a low risk rating.) |
