NatureServe Status

Global Status: G2
Global Status Last Reviewed: 27Nov2012
Global Status Last Changed: 25Mar1991
Ranking Methodology Used: Ranked by calculator
Rounded Global Status: G2 - Imperiled
Reasons: This edaphic species is known from 32 locations in the San Andres and Sacramento mountains of south central New Mexico. The plants are locally abundant but restricted to limited suitable habitat. The plants primarily spread by cloning, but also by limited sexual reproduction.
Nation: United States
National Status: N2

NatureServe Global Conservation Status Factors

Range Extent Comments: Occurs in the San Andres Mountains and Sacramento Mountains of Southern New Mexico (USFWS 2011h).

Number of Occurrences: 21 - 80
Number of Occurrences Comments: 32 populations documented (USFWS 2011h).

Overall Threat Impact: High
Overall Threat Impact Comments: Potential threats include trampling due to illegal livestock grazing, expanded military activities, communication tower and line construction, and mineral, oil and gas exploration (USFWS 2001d). Other threats could include browsing by deer, rabbit, elk, and rodents, as well as insect larvae herbivory or drought (USFWS 2001d). Forests surrounding populations are becoming increasingly dense due to a history of fire prevention. Fire, natural or prescribed, could increase the extent and number of populations (USFWS 2011h).

Intrinsic Vulnerability Comments: Low seed set (USFWS 2011h).

Environmental Specificity Comments: Occurs on gypseous soils (USFWS 2011h).

Ecology & Life History
Help
Basic Description: An erect perennial herb that grows to about 1-1.8 dm tall. Tubular orange-red flowers borne singly along the upper part of the stem; in flower from July through September. The plants are rhizomatous, and reproduction is primarily asexual.
Duration: PERENNIAL
Reproduction Comments: Nutlets remain inside the calyx which has a mucilaginous surface when wet. The sticky calyx sticks to surfaces, therefore limiting long distance dispersal (USFWS 2001d).

Plants typically have a low seed set which seems to be a genetic characteristic of the species (USFWS 2011h).

Terrestrial Habitat(s): Forest/Woodland, Woodland - Conifer
Habitat Comments: Steep gravelly north- and east-facing slopes with loose, gypseous-limestone soils at about 2000 m elevation. The surrounding plant community is an open pinyon-juniper woodland (USFWS 2001d, NMNP PAC 1984).
