No. That's right.
There are a variety of some 30 species concepts that are out there to address a variety of different priorities, but the biological species concept that you referred to, the ability to interbreed, is still one that's quite important in the scientific community.
But the act refers to “wildlife species” and it has a very specific definition of “species”, which is as defined in the act. It can include what we would call “biological species”, but it can also refer to specific sets of differentiated populations or units within a species, subspecies, or groups of populations that are in a particular region.
These are decisions that are made...well, I don't want to say they're made at the COSEWIC table, but they're decisions that are discussed intensely in the assessment of species. That's where those judgments are made on the basis of the best available scientific information.
