NatureServe Status

Global Status: G3
Global Status Last Reviewed: 10May1999
Global Status Last Changed: 26Jan1993
Rounded Global Status: G3 - Vulnerable
Reasons: Narrowly endemic to Nevada, Mirabilis pudica is relatively abundant within its small geographic range. The species comprises two varieties that occur in the southern portion of the state only. M. pudica var. pudica is more widespread in Nevada; it is found in Nye, Lincoln, and Clark Counties. The plants are found on alkaline flats and disturbed sandy playas at elevations of 100 - 444 m. They thrive on these disturbed sites and colonize quickly. There are not any known active threats to this species. The global rank of this species may be estimated based on unrecorded information in Nevada's files, and so may not correspond with the number of stated occurrences.
Nation: United States
National Status: N3

Number of Occurrences:  
Number of Occurrences Comments: In Nevada, there is one record for an extant occurrence (Nevada Natural Heritage Program 1999).

Population Size Comments: These plants thrive on disturbed sites and colonize quickly (Mozingo and Williams 1980). Infrequent (Kartesz 1988).

Overall Threat Impact Comments: No known active threats (Jim Morefield, personal communication 1999).

Intrinsic Vulnerability Comments: Readily invades disturbed soils, because it has the ability to survive disturbance on at least some soils (Beatley 1977).
