Inventory of the Orchidaceae Familyin Pululahua Geobotanical Reserve

Pululahua Geobotanical Reserve; Inventory; Orchidaceae family.Abstract
The Pululahua Geobotanical Reserve has been identified as an area with an important plant diversity (905 spp. - Cerón, 2004), despite being one of the smallest protected areas within the PANE (Heritage of Natural Areas of the State) (3356 ha.) For this reason, in 2013, it was decided to start with the project "Inventory of the Orchidaceae Family in the Pululahua Geobotanical Reserve", which had the objective of gathering information on the wealth of species of this family within the protected area. The sampling was carried out from 2013 to the present, through the sweeping methodology that consists of the registration of the species found in the trails and roads within the protected area. A total of 153 species grouped in 57 genera have been identified, of which the most representative are Epidendrum (29 spp.), Pleurothallis (16 spp.), Maxillaria (10 spp.), Cyrthochilum (8 spp.), Lepanthes (5 spp.). Regarding the state of conservation, 27 species are considered within a category, according to the International Union for the Conservation of Nature: 13 as Vulnerable (VU), 4 as Near Threatened (NT), 8 in Minor Concern (MC) and 2 with Data Deficient (DD) (IUCN, 2012). In relation to Endemism, 19 species are considered endemic to Ecuador. The data obtained during this study shows an increase of 48 species in relation to what Cerón (2004) obtained, with which it can be seen that there is still a lot of information to be obtained within the protected area. The presence of species considered as Vulnerable prioritize the conservation of this family within the reserve to be a taxonomic group susceptible to be affected by the illegal trafficking of species.
