CALDERON MOYA-MENDEZ, Natalia; CERONI STUVA, Aldo  and  OSTOLAZA NANO, Carlos. Distribution and state of conservation of the genus Haageocereus (Cactaceae Family) in the department of Lima. Peru. Ecol. apl. [online]. 2004, vol.3, n.1-2, pp.17-22. ISSN 1726-2216.

Haageocereus genus distribution and conservation status in the Department of Lima (Perú) was studied. Plants were collected in 12 places located in Canta, Huaral, Huaura, Huarochirí, Lima and Oyón provinces, from 180 up to 2500 masl. The number of taxa evaluated was 12: 4 species, 6 subspecies and 2 hybrids, and also 2 forms, which were classified into the following conservation categories: Vulnerable (3), Endangered (5) and Critically Endangered (6). The lowest distribution species was H. tenuis (Ritter) Rauh & Ostolaza, which has been included into the "Critically Endangered" category because of the high vulnerability of its sole habitat. On the other side, the highest distribution species was H. acranthus (Vaupel) Backeberg, categorized as "Vulnerable". Disturbed localities are Cajamarquilla, Santa Clara and on the way to Huacho (118 km North Panamerican Highway), where ex situ conservation plans for H. pseudomelanostele (Werdermann & Backeberg) Backeberg and H. tenuis (Ritter) Rauh & Ostolaza species are expected to be undertaken.

Keywords : Cactus; distribution; conservation; categorization; genus.
