United States

Rounded National Status Rank: N3 - Vulnerable

Rounded Global Status Rank: T3 - Vulnerable

Reasons: This subspecies is not as numerous as it once was and is probably declining in some areas more rapidly then we previously thought. Habitat is declining due to development and recreation pressures.

Global Short Term Trend: Relatively stable to decline of 30%

Comments: Declining in some areas particularly those close to developing communities and areas with heavy recreation.

Degree of Threat: B : Moderately threatened throughout its range, communities provide natural resources that when exploited alter the composition and structure of the community over the long-term, but are apparently recoverable

Comments: Threatened by development, recreation, water diversions, and habitat alteration.

Global Protection: Few (1-3) occurrences appropriately protected and managed

Comments: Probably some occurrences are protected but many are not.
