* Each state or province's Conservation Data Centre assigns subnational ranks. They are not legal designations, but reflect the relative rarity of the species within that jurisdiction.
- Extremely rare; usually 5 or fewer occurrences in the state/province or very few remaining individuals; often especially vulnerable to extirpation.
- Very rare; usually between 5 and 20 occurrences in the state/province or with many individuals in fewer occurrences; often susceptible to extirpation.
- Rare; usually between 20 and 100 occurrences in the province; may have fewer occurrences, but large number of individuals in some populations; may be susceptible to large-scale disturbances.
- Uncommon; but not rare; some cause for long-term concern due to declines or other factors.
- Common; widespread and abundant.
- Historically known from the state/province, but not verified recently (typically not recorded in the state/province in the last 20 years).
- Apparently extirpated, with little likelihood of rediscovery. Typically not seen in the state/province for many decades, despite searches at known historic sites.
- Unrankable. Currently unrankable due to lack of information or due to substantially conflicting information about status or trends.
- Not ranked.
