Justification of Red List category
This species has a very restricted range and is suspected to have a very small population size that could be sufficiently threatened by the introduction of invasive predators or disease, or through wildfire to drive the species to Critically Endangered within a short time. Therefore, it is listed as Vulnerable.
Population justification
Given its highly restricted range, the population size is likely less than 1,000 mature individuals, placed here in the range of 250-999 mature individuals.
Trend justification
The population is suspected to be stable in the absence of evidence for any declines or substantial threats.
Geospiza acutirostris is found only on the island of Genovesa, in the Galápagos Islands, Ecuador, with a maximal area of occupancy of c. 15 km2.
This species is found in arid scrub habitat (Jaramillo 2016).
The species occurs on one small island, hence its restricted range puts it at risk from a variety of threats, particularly the introduction of invasive predators and disease, and also wildfire and a loss of genetic diversity (Jiménez-Uzcátegui et al. 2019). Its habitat may also be threatened in the long-term as climate change results in dramatically altered climatic conditions (Jiménez-Uzcátegui et al. 2019).
Conservation Actions Underway
Conservation Actions Proposed
Attempt to prevent the introduction of invasive species onto Genovesa.
