There really no longer is a STANDARD for North America or anywhere else for that matter. Any committee of experts you would put together would come up with a different list.
The reasons for this are twofold. (1)There are several different competing definitions of species, and wholely competing ideologies behind them. (2) Some of those ideologies cannot accept the reality of subspecies. They either must deny geographic differences have any meaning, or make full species out of the subspecies.
My advice for non-experts, take the two lists (CNAH and SSAR) and combine them. IMO it is best to take the names that most emphasize the biodiversity that some find hard to accept is really out there.
An example: Most recent evidence shows that Bufo punctatus, the Red-spotted Toad, is three separate species. Only the Chihuahuan Desert Red-spotted Toad is B. punctatus. The Baja Red spotted toad is B. beldingi. The Sonoran-Mojave red-spotted toad is presently without a name.
