This species is listed as Endangered because it has a very restricted distribution with an estimated range of 30 km2, it is known from only one location, and there are potential threats that may be causing continuous decline in the extent and quality of the habitat. Further research is needed to better determine its population size and trends and the effect of the potential threats.

Geographic Range [top]

Range Description:Stenocereus humilis is endemic to the Dagua Valley, Colombia (Hunt et al. 2006). It grows in a 14 km stretch in the Dagua Valley between Orten Dagua and Lobo Guerrero at elevations between 700 and 1,000 m asl. The extent of occurrence and area of occupancy of this species is estimated to be approximately 28 km2 (calculated by multiplying the length of the valley where it occurs (14 km) by the width (2 km), measured using Google maps).

Habitat and Ecology:This species inhabits dry tropical/subtropical habitats. It forms dense thickets.
Continuing decline in area, extent and/or quality of habitat:Yes

Use and Trade [top]

Use and Trade: There is no information available about uses of this species.

Threats [top]

Major Threat(s): The valley where the species occurs is traversed by a main road/highway and there are several exploitation activities in the municipality of Dagua (population 40,000), mainly agriculture, livestock, forestry, and mining. Therefore, it is very likely that this species is impacted by some these activities.

Conservation Actions [top]

Conservation Actions: It is not known whether this species occurs in any protected areas. Research is needed to better determine the distribution and population size and trends of this species.
