Heliodoxa aurescens

NOTES

To elaborate our model we removed uncertain localities such as those localities with no coordinates and all records with coordinates laying down in sites with estimated elevations above 1,156 m. Also one record in BioMap from west Nariño, which represent corrupted data in the database was deleted before modelling.

The habitat suitability model generated in Maxent showed some areas suitable in climatic terms for this species west of the Andes including areas along the Pacific slope of the Western Andes, the northern serrania del Baudo and a very few sections of the mid and high Magdalena Valley. Those areas are not known to be occupied by this species and were deleted from our final potential distribution map. It is important to highlight that an extensive area in the northern Amazonia and a few in the southern Amazonia were not predicted as suitable by our model and this was noted in our maps.

Assuming that the distribution of the species may have filled the complete climatic model generated plus the areas not predicted but likely suitable, its distribution today in remnants of forest is about 432,842 km2, which corresponds to a loss of 9 % of its potential original distribution due to deforestation.
