IUCN Red List Assessment

Red List Criteria
Criterion A (population reduction):
Threats to this species have not ceased and are not reversible. Population decline occurred in the past and is projected for the future. Habitat destruction has occurred for decades in the range of the dwarf deer. Its extent of occurrence (EOO) has declined in Bolivia and Peru (at least 40% of the expected range in Bolivia somehow degraded due to colonization, deforestation, and burning for agriculture and cattle grazing (see Threats)). An inferred population decline based on habitat reduction suggests assignment to the category of VU A4c.
Criterion B (geographic range size):
Area of occupancy (AOO) based on 60+ record points in Bolivia (with 2x2 km quadrats = 224 kmÂ², and with 4x4 km quadrats = 656 kmÂ² ) and 49 points in Peru (104 kmÂ² or 368 kmÂ²) is within the range size of the VU category (500-2,000 kmÂ²). Points may be grouped into 5-7 areas in Bolivia and 7-9 in Peru, but include some old collecting / report sites that are now densely settled and degraded. The small number of locations, restricted AOO, and the decline in habitat range support the status of Vulnerable.

The Dwarf Brocket (Mazama chunyi), or Chunyi, is a small species of deer native to the Andean highlands in western Bolivia and south-eastern Peru, where found in forest and páramo. Its pelage is redddish-brown with dark grey foreparts and neck. The underparts are lighter brown, and the muzzle short and thick. It weighs approximately 11 kilograms.
A little studied species of brocket deer, the IUCN considers the Dwarf Brocket as Vulnerable. Research has occurred in the forests of Bolivia, expanding known localities and modelling geographic distribution; while as much as 40% of the habitat was degraded or fragmented, the rest showed good conservation. This led to the recommendation of treating it as Vulnerable.
