There are no current severe threats to this species, but it is potentially vulnerable to habitat degradation due to overgrazing and trampling, as well as salt mining. These threats are however unlikely to rapidly cause this species to become in danger of extinction.

Cynodon polevansii is a widespread, but highly localized habitat specialist (AOO <50 km²). It is currently known from ten subpopulations, but is possibly easily overlooked and more common than records suggest. The population is not declining.

Population trend
De Wet and Harlan (1971) report that C. polevansii readily hybridises with the widespread and common C. dactylon (with which if often co-occurs), and that it should be considered to be only a variety of that species. Fish et al. (2015) state that further collections and research is needed to resolve taxonomic problems in Cynodon. Hahn (2013) indicates that C. polevansii can be readily distinguished from C. dactylon, and doubts that there should be taxonomic uncertainty over the validity of this species.
