IUCN Red List

Lasiancistrus caucanus is broadly distributed throughout Atlantic and Pacific coast drainages in eastern Panama and Colombia. Extent of Occurrence is estimated to be 502,659 km2. Total population size is unknown, but this species is abundant throughout much of its range. Potential localised and regional threats include land-use changes and deforestation associated with agricultural expansion, pollution and sedimentation resulting from mining activities, and additional sources of pollution from industrial and domestic waste water discharge. However, there is currently no indication of major population decline. As such, L. caucanus is assessed as Least Concern. (IUCN 2020).
