Spatial analysis and structural connectivity in the landscape with wax palm (Ceroxylon quindiuense) and its relationship with birds, butterflies, and mammals in Tolima, Colombia
Wax palm (Ceroxylon quindiuense H.Wendl. ex H.Karst) forests are constantly threatened ecosystems by agricultural and cattle systems. Research regarding these ecosystems are restricted to their fauna and flora. However, there is no information about the structural aspects of landscape connectivity. This is a key element not only of their sustainability and distribution but also their management and protection. For this reason, this study aims to define the structural connectivity of wax palm landscapes and how they relate to birds, diurnal Lepidoptera, and mammal communities in Ibagué, Cajamarca, and Roncesvalles (Tolima, Colombia). Highly intervened landscapes were identified based on satellite images. Through analyses at the patch, class, and landscape level, correlations were made with each fauna component. In Ibagué and Cajamarca, this landscape has wooded areas with good connectivity, important to interior and periphery species, while Roncesvalles has poor connectivity for this land cover. The correlation between landscapes and fauna showed that isolation is linked to birds’ richness, the core area is linked to butterflies’, and the size of fragments and their isolation is linked to mammals’. This highlights the importance of this habitat to the conservation and sustainability of these species.
