Justification:
This species has a very small range (and probably a small population), which is presumably declining in response to the impact of changing agricultural techniques and conversion to plantations. It would qualify as Endangered, but is known from seven locations, and is consequently listed as Vulnerable.

Geographic Range [top]

Range Description:	Premnoplex tatei occupies a restricted range in the mountains of north-east Venezuela. It occurs on the Paria Peninsula, Sucre, and in the Turimiquire Massif (both the Serranía de Turimiquire west of the San Antonio valley, and the Cordillera de Caripe to the east) on the borders of Sucre, Anzoategui and Monagas. In the Serranía de Turimiquire, it has been recorded on cerros Peonía, Turimiquire, Macanillal (Colvee 1999) and Negro (Boesman and Curson 1995) and, on the Paria Peninsula on cerros Humo, El Olvido and Azul. Apart from records in 2005-2006 on cerros Turimiquire, Quiriquire ("Piedra 'e Mole'") and Macanillal in the Turimiquire massif and from the Paria Peninsula (Hernández et al. 2006, Sharpe in litt. 2011), there have been few recent records, and none from cerros Peonía or Azul.

Population [top]

Population:	The population is estimated to be in the band 2,500-9,999 individuals in total, equating to 1,667-6,666 mature individuals, rounded here to 1,500-7,000 individuals. In 1988, 2.4 pairs per hectare were estimated on Cerro El Olvido (Bond et al. 1989) and, in 1993, 0.8 individuals per hectare were found in Cerro Humo (Evans et al. 1994a). The population on the Paria Peninsula has been estimated at 3,600 individuals (Bond et al. 1989).
Population Trend:	Decreasing

Habitat and Ecology [top]

Habitat and Ecology:	In the Cordillera de Caripe, it is known from 1,200-2,400 m. On Cerro Humo, it occurs at 1,100-1,200 m and, on Cerro El Olvido, at 800-885 m. It inhabits the understorey (up to 2 m from the ground) of montane humid forest, where there is extensive epiphytic growth.
Systems:	Terrestrial

Threats [top]

Major Threat(s):	There has been widespread clearance for agriculture and pasture in the Cordillera de Caripe. Even in El Guácharo National Park there is clearance, repeated burning and understorey removal for coffee (Boesman and Curson 1995, Sharpe and Lentino 2008). The slopes of Cerro Negro are largely bare with the more obvious forest patches actually shade-coffee plantations (Boesman and Curson 1995). There is conversion to coffee, mango, banana, and citrus plantations in the Turimiquire Massif, but extensive forested areas remain (Colvee 1999, Hernández et al. 2006, Sharpe in litt. 2011). On Cerro Humo, increases in cash-crop agriculture since the mid- to late 1980s, have resulted in uncontrolled burning and forest degradation.

Conservation Actions [top]

Conservation Actions:	Conservation Actions Underway It is formally protected by Paria Peninsula and El Guácharo National Parks. The latter reserve was recently expanded to include a further 500 km² of largely undisturbed forest (Gabaldón 1992). The Turimiquire massif is a Protective Zone, but in practice the legal status is not enforced (Sharpe and Lentino 2008). It is similarly considered Vulnerable at the national level in Venezuela (Sharpe 2008). Conservation Actions Proposed Survey El Guácharo National Park, Los Cumbres de San Bonifacio, Serranía de Turumiquire, Cerro Azul and other suitable areas (Boesman and Curson 1995, Rodríguez and Rojas-Suárez 1995, C. J. Sharpe, J-P. Rodríguez and F. Rojas-Suárez in litt. 1999). Develop alternative agricultural techniques for areas adjacent to Paria Peninsula National Park (Rodríguez and Rojas-Suárez 1995).
