Rank Reasons
Pinaropappus parvus is a regional endemic from Texas and northern Mexico probably known from fewer than 100 occurrences globally.
Range Extent Comments
Pinaropappus parvus is endemic to the Chihuahuan Desert Region of Trans-Pecos Texas, southern New Mexico and Coahuila, Mexico (J. Poole in Henrickson & Johnston, in prep.). In Texas it is known from the Guadalupe Mountains of Culberson County; Victorio Canyon in the Sierra Diablo of Hudspeth County; and the Apache Mountains of southeastern Culberson County (Warnock, 1974). In Coahuila it is known from the Sierra Mojada (J. M. Poole in Henrickson & Johnston, in prep.; TEX-LL, 1998).
Occurrences Comments
Given its restriction to a few mountainous regions in the Chihuahuan Desert region, it is likely that the taxon is represented by fewer than 100 occurrences globally.
Threat Impact Comments
Specific threats to the taxon are unknown.
