High priority species would still be those confronting a high magnitude, imminent threat, and the most noticeable effect would be a reduction in priority rankings from twelve to eight resulting from the shift from a ternary criterion based on whether the species belongs to a monotypic genus, a polytypic genus, or is merely a subspecies to a binary criterion based on whether the species is ecologically significant or not.
