Existing Protection or Other Status Designations

Presently, E. p. persius enjoys no specific legal protection in Canada through either federal or provincial legislation. It is considered to be extirpated from Ontario by the Ontario Ministry of Natural Resources (NHIC 2001).

In the United States, E. p. persius is designated as Endangered in Indiana, New Hampshire, New York and Ohio; Threatened in Michigan and Massachusetts; and of Special Concern in Connecticut and Pennsylvania. It is considered by relevant state authorities to have been extirpated from Maine, and it has not been recorded within the last 20 years in New York, New Jersey or Maryland. Elsewhere, it is mostly considered critically imperilled, but in its presumed stronghold of Michigan, it is considered to have a sub-national rank of S3. Global, national and sub-national conservation ranks for all jurisdictions where it is known to have occurred are presented in Table 1.

Note:

G5T2T3 = Globally secure as a species, but the subspecies is considered to be very rare to rare.
NX = Nationally extirpated.
N2N3 = Nationally very rare to rare.
SX = Extirpated in the state or province.
SH = Historically known from the state or province, but not reported in the last 20 years.
S1 = Extremely rare in state or province; usually 5 or fewer occurrences in the state or province or very few remaining individuals; often especially vulnerable to extirpation.
S2 = Very rare in state or province; usually between 5 and 20 occurrences in the state or province or with many individuals in fewer occurrences; often susceptible to extirpation.
S3 = Rare to uncommon in state or province; usually between 20 and 100 occurrences in the state or province; may have fewer occurrences, but with a large number of individuals in some populations; may be susceptible to large-scale disturbances.
S? = Unknown status, or if following a numbered S-rank, indicates uncertainty in the ranking.
E = Endangered, T = Threatened, SC = Special Concern

Of the two sites where E. p. persius has been confirmed to have historically occurred in Ontario, one is owned and controlled by the conservation group Lambton Wildlife Incorporated, and the other is owned and controlled by the Ontario government. Specific protection is not provided at either site, although Lambton Wildlife Incorporated forbids collecting of flora and fauna on its property without prior written permission.
