When a species is in a critical state what may take place?

Under the Endangered Species Act, critical habitat designations are to be finalized at the same time that we issue the final listing rule for a species, unless a critical habitat designation is not prudent for the species, or it is not yet determinable. In cases where critical habitat is not determinable at the time the species is listed, we may extend the deadline for designating critical habitat by one additional year.
