The Greater Grison, Galictis vittata, is a poorly known species in Colombia. Throughout its range major knowledge gaps exist regarding its ecology and conservation. To compile and analyse information about the species’ distribution records in the department of Cordoba, Colombia and assess its presence probability according to land scape attributes, we conducted a literature review of all wildlife studies in the region and compiled all possible direct presence records of the species in the department. We generated random location points and characterized each distribution and random location by their distance to landscape attribut es and land-cover type and modelled landscape presence using a Multiple Logistic Regression approach.
We found 33 records of the species in Cordoba with most of the records distributed in the subregion of Alto Sinú (36%). Higher presence probabilities are localized in areas near forests mostly in the southern parts of the department, showing the species is still related with the largest forest blocks. Grisons appears to potentially tolerate some levels of disturbance but is still dependent to forest. The influence of natural habitats and abundance across the department and other areas of its distribution remain to be evaluated.
