Population justification: The global population size has not been quantified, but this species is described as 'fairly common' (Stotz et al. 1996).

Trend justification: The population trend has not been estimated directly. The only threat known for this species is forest clearance for agricultural expansion (del Hoyo et al. 2002). Tracewski et al. (2016) measured the forest loss within the species’s range between 2000 and 2012 as c. 740 km². This roughly equates to a rate of forest loss of 1.4% over three generations (12.6 years) for this species. Due to its tolerance of secondary, converted habitats, Arrowhead Piculet may not be severely affected by deforestation. It has even been suggested that the species might benefit from forest loss as deforestation is opening up new areas of suitable habitat (O. Ottema in litt. 2018). In the absence of evidence for any declines or substantial threats, the species is tentatively assessed as being stable.
