Threats and Conservation
editLocalized threats may exist, but on a range-wide scale no major threats are known. Listed as Least Concern in view of the large extent of occurrence, large number of subpopulations, large population size, and lack of major threats. The trend over the past 10 years or three generations is uncertain but likely relatively stable, or the species may be declining but not fast enough to qualify for any of the threatened categories under Criterion A (reduction in population size). Currently, this species is of relatively low conservation concern and does not require significant additional protection or major management, monitoring, or research action.[1]
