Assessment Information [top]

Red List Category & Criteria: Near Threatened ver 3.1
Year Published: 2012
Date Assessed: 2012-05-01

This species has a small range, within which it is uncommon and probably declining. Future increases in human encroachment within the range could place this species at higher risk of severe declines. However, the range is not yet severely fragmented or restricted to few locations. For these reasons, the species is classified as Near Threatened.

Geographic Range [top]

Range Description: Melanopareia maranonica occurs in north-west Peru (local in the upper río Marañón valley of Cajamarca) and extreme south Ecuador (Zumba region of south Zamora-Chinchipe) (Ridgely and Tudor 1994).

Population [top]

Population: The population size of this species has not been quantified, but it is described as local and uncommon.
Population Trend: Decreasing

Habitat and Ecology [top]

Habitat and Ecology: It is uncommon and local in dry deciduous forest, arid lowland scrub and riparian thickets at 200-800 m, where it apparently tolerates a degree of disturbance (Ridgely and Tudor 1994, Parker et al. 1996, Stattersfield et al. 1998, R. Webster and R. A. Rowlett in litt. 1998).

Systems: Terrestrial

Threats [top]

Major Threat(s): Its habitat in the Marañón drainage has progressively deteriorated during a prolonged period of cultivation (Ridgely and Tudor 1994), while the spread of oil palm plantations, cattle-ranching and logging are all serious threats within its small range (Dinerstein et al. 1995). Oil extraction is a potential future problem (Dinerstein et al. 1995).

Conservation Actions [top]

Conservation Actions: Conservation Actions Underway
Conservation Actions Proposed
Conduct ecological studies to determine whether this species can genuinely tolerate secondary or disturbed habitats. Re-visit known localities to determine rates of population change and habitat loss. As a precaution, protect significant areas of suitable habitat.
