Resumen
The Dictyocaryum lamarckianum palm is a dominant species of montane forests that forms extensive stands. In the site of Las Palmeras Natural Reserve in Cubarral Meta, it was found that this palm is the habitat of the population of the yellow-eared parrot (Ognorhynchus icterotis), becoming its main source of food and nesting site. Due to the ecological importance of the palm, we characterize its population structure and evaluate the production of fruits as a key resource for the conservation the yellow-eared parrot. Two parcels of one hectare each were established, morphological and structural data of all individuals was taken, Principal Components Analysis was carried out and the population categories were established. Three racemes were collected to register the quantity and weight of the fruits, and the production fruit was recorded in stand the ten hectares, from the year 2015 to 2018. A population of 16 993 individuals was found in two hectares, distributed in seedlings with 11,131 individuals (65.5%), juveniles with 5 851 individuals (34.24%) and Adults with 11 individuals (0.06%). The production of fruits had large annual fluctuations with an average of 153 081 fruits, the year of greatest production was 2017 with 342 560 fruits, while in 2016 only 19 269 fruits were produced. The management of the D. lamarckianum palm as a strategy for the conservation of the yellow-eared parrot should guarantee the presence of adult individuals and should include seedling rescue activities to plant in other areas. To counteract the periods of scarcity of fruits, the zone should be enriched with other species that provide food for the Yellow-eared Parrot.
