Justification of Red List category
This species is classified as Near Threatened because it has a moderately small population with is suspected to be in decline due to the degradation and loss of its habitat, mainly for agricultural purposes.

Population justification
The species occurs at low densities; distance sampling along transects found on average 4 individuals/km² (Devenish et al. 2020). Multiplying local densities by the area of suitable habitat at a site yielded a minimum population estimate across the study area of 1,575 (95% CI: 638-3,185) individuals (Devenish et al. 2020). This roughly equates to a minimum of 1,000 mature individuals and therefore, the overall population is here placed in the band 1,000-2,499 mature individuals.

Trend justification
Habitat degradation within the range is suspected to be driving a slow population decline. The rate of decline has not been quantified, but is unlikely to exceed 10% over ten years.

Ochthoeca salvini is endemic to extreme north-west Peru, from Tumbes south to La Libertad, where it is considered uncommon and occurring at low densities (Ridgely and Tudor 1994, Devenish et al. 2020). In 2008, it was recorded near the town of Zapotillo in south-west Ecuador, very close to the Peruvian border (Athanas et al. 2009; Ordóñez-Delgado et al. 2016). 

It inhabits lowland Algarrobo Prosopis pallida forests, arid scrub, arid scrub with scattered Algarrobo trees from lower parts of the hills of the west slope of the Andes, to dense deciduous dry forests at 700 m and occasionally higher (F. Angulo in litt. 2007; Devenish et al. 2020). It shows a preference for trees with a large girth (Devenish et al. 2020). It has been considered to usually occur near watercourses (Ridgely and Tudor 1994; Parker et al. 1996), but it has also been found in areas where the nearest water source is about 25 km away and on heavily grazed, deforested, arid and low density type forests without vine tangles (F. Angulo in litt. 2007). It perhaps undertakes local seasonal movements (Barrio 1997).

Habitat destruction is the principal threat, with selective logging, understorey clearance, loss of riverine thickets to irrigated agriculture, large-scale agriculture in the coastal plains and over-grazing by goats the main processes (Best and Kessler 1995, Stattersfield et al. 1998, Devenish and Piana 2019, Devenish et al. 2020). Mining and mineral extraction is a further threat, but currently present at only a small number of sites (Devenish et al. 2020).

Conservation Actions Underway
None is known.

Conservation Actions Proposed
Monitor the population at key sites. Research the effects of grazing and wood cutting on populations of the species. Protect significant areas of lowland dry forest, in both strictly protected areas and community led multiple use areas. Declare key sites of occurrence as KBAs and protected areas. Establish a network of protected areas. Restore habitat. Work with local farmers to restrict goat grazing. Raise awareness for the species among local farmers and industry.
