Taeniophallus nebularis has been assessed as Data Deficient as the species is only known from its type locality. Although it is thought to have a restricted range of approximately 600 km², being isolated to an 'island' of cloud forest within otherwise humid shrubland habitat, the area surrounding the type locality itself is protected by occurrence within a National Park. Although lower elevation environments near the type locality are affected by ongoing habitat degradation of the forest as a result of destructive agricultural practices, this is unlikely to affect this species throughout its range. Whether or not climate change will be having a positive or negative effect on this species' cloud forest habitat in the future is still under discussion. More information on the distribution of this species is required.

Geographic Range [top]

Range Description:This species is known only from its type locality, from the trail between Las Melenas and Cerro Humo, at 800 m elevation, Peninsula de Paria, Estado Sucre, Venezuela. The area of cloud forest in which the species was found has an area of approximately 600 km². The surrounding area is dry scrubland habitat, and it is assumed that the species is restricted to the forest habitat.

Habitat and Ecology [top]

Habitat and Ecology:This species is known from cloud forest habitat. The cloud forest in which the species is found is surrounded by humid scrubland, and it is assumed that the species is restricted to the forest habitat.

Threats [top]

Major Threat(s): Encroaching human population has resulted in degradation of the natural habitat, especially at lower elevations; conversion of land to agriculture, which is done in the traditional way, involving clearing and burning of the vegetation before cultivation, is one of the major factors causing degradation of the habitat in this region. The type locality itself, however, is in a protected area (Parque Nacional Panínsula de Paria). Cloud forests have also been highlighted as a habitat particularly vulnerable to climate change, though some studies are starting to question whether the impact of climate change might be positive in some cloud forest areas due to increased humidity (E. La Marca pers. comm. 2010).

Conservation Actions [top]

Conservation Actions: The species is known from the Península de Paria National Park, IUCN category II. Further research on the distribution of this species is required.
