Existing Protection or Other Status Designations

International status 

Uropappus lindleyi is not covered under the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES), the Endangered Species Act (U.S.) or the IUCN Red Data Book. Globally, U. lindleyi has a rank of G5, indicating that, on a global scale, the plant is considered "common; widespread and abundant" (NatureServe Explorer 2003).

This species is listed as, S1 (“critically imperiled”) only in Utah (NatureServe Explorer 2003). In Arizona, California, Idaho, Nevada, New Mexico, Oregon, Texas and Washington this species is ranked SNR, meaning that its ranking status has not yet been assessed (NatureServe Explorer 2003).

National and provincial status

In Canada, U. lindleyi is restricted to British Columbia, and has national and provincial rankings of N1 and S1, respectively. These are the most critical ranks that can be applied to species at the national and provincial levels and indicate that the species is "critically imperiled because of extreme rarity (typically five or fewer occurrences or very few remaining individuals) or because of some factor(s) making it especially vulnerable to extirpation or extinction" (NatureServe Explorer 2003). The species is also included on theBritish Columbia Ministry of Environment red list (Douglas et al. 2002).

Uropappus lindleyi could be a candidate for listing under the provincial Wildlife Amendment Act (2004) due to its British Columbia Ministry of Environment red-list status.
