BirdLife International and the IUCN classify the Rufous-breasted Spinetail as Least Concern on the basis that it has a range larger than that required for Vulnerable (<20,000 km2), its population trend seems to be stable, and its population is too large to be considered Vulnerable (<10,000 mature individuals in population decline) (BirdLife International 2012).
Parker et al. (1996) report that lowland scrub habitats, such as that occupied by Rufous-breasted Spinetai, are being lost or degraded by human activity, and consider the spinetail to have a medium conservation priority, in which it is not in any short-term danger, but will decline if current rates of habitat loss persist. The spinetail will not inhabit severely or completely deforested regions (Dickey and van Rossem 1938), but its population could expand if more secondary habitat is created (Remsen 2003).
Effects of human activity on populations
Dry forests in the Neotropics are severely degraded, and a major factor for this is human activity (Parker et al. 1996). However, the Rufous-breasted Spinetail's use of secundary scrub habitats as well can prevent many of its populations from disappearing (Remsen 2003). The impacts humans will have on the spinetail will depend on how much acceptable secundary habitat increases compared to the rates of complete deforestation, which is not tolerated by the bird (Dickey and van Rossem 1938).
