ENDANGERED SPECIES ACT PROFILE

PROTECTION STATUS: Endangered

YEAR PLACED ON LIST: 1997

CRITICAL HABITAT: None

RECOVERY PLAN: None

RANGE: The mountains of southeastern Arizona in the San Pedro watershed in Santa Cruz and Cochise counties

THREATS: Habitat loss and degradation from livestock grazing, groundwater pumping, and water diversion; competition with nonnative species; illegal collection; and possibly fire suppression

POPULATION TREND: Five populations of Canelo Hills ladies’ tresses existed as of 2007. Estimating population size and stability is difficult because nonflowering plants are hard to find and dormant plants go uncounted.
