The conservation status Blue-and-gold Tanager has been listed by IUCN Red List as Near Threatened (BirdLife International 2011). It received this categorization due to its small estimated range, about 8900 km2. Further, it has been described as uncommon with evidence of population decline and major threats. Parker et al. (1996) considered this species of "medium" conservation priority relative to other Neotropical birds due to sensitivity of human disturbances.
Effects of human activity on populations
Human activity such as burning, logging, and other intense agricultural use has been known to decrease the numbers of Blue-and-gold Tanagers (Birdlife International 2011). Parker et al. (1996) considered Bangsia arcaei to have a medium degree of sensitivity to human disturbance relative to other Neotropical birds. In Costa Rica, Bangsia arcaei is known from the following protected areas: Reserva Biológica Alberto Manuel Brenes (Arias and Granados 2012), Reserva Biológica Bosque Nuboso Monteverde (Fogden 1993), and Brauillo Carillo National Park. In Panama it is known from La Reserva de Fortuna, Chiriquí (Tejera 2001).
