GRANADOS-RODRIGUEZ, Federico et al. Distance to vegetation, road layout, and run overs of wild vertebrates in Puntarenas, Costa Rica. Cuadernos de Investigación UNED [online]. 2024, vol.16, n.1, pp.212-220. ISSN 1659-4266.  http://dx.doi.org/10.22458/urj.v16i1.5260.

Introduction: Understanding the impact of roads on wildlife is crucial for implementing protective measures; Costa Rica is among the most studied tropical countries on this regard, but some areas remain poorly known. Objective: To evaluate the relationship between roadkill frequency, road layout and distance to vegetation. Methods: We worked over 15km from April 8 to 10, 2016, in the Pacífica Fernández National Highway, Puntarenas, Costa Rica. We counted all visible roadkills. Results: We recorded 56 roadkill individuals, primarily toads (Rhinella horribilis) and iguanids. Close vegetation increased the number of victims, while straight versus curved road sections did not. Conclusions: We recommend barriers, speed reducers, and suitable wildlife crossings, particularly in areas with dense vegetation close to the road.
