Pest species cause significant ecological, social and economic impacts, and programs to control them usually target specific landscape features when pests use these to disperse. Roads or railways are often used by pest species as dispersal corridors, but little is known about the specific characteristics of these human infrastructures that facilitate pest species dispersal. This is particularly evident in the case of native agricultural vertebrate pests like the European wild rabbit (Oryctolagus cuniculus) in the Iberian Peninsula (IP). Rabbit damage to agricultural production in IP has increased notably in recent years. This study uses a ‘favourability function’ to model the extent to which macroecological favourable conditions for rabbits and different fine-scale variables, including environmental, anthropogenic and agricultural factors, favour the presence of rabbit warrens on the verges of a motorway network in southern IP. For this purpose, we collected rabbit warren locations during car transects using CyberTraker 3.0 installed in a pad along 787 km of motorways. Our results revealed that rabbit warren distribution was widespread along the verges. Rabbit warren presence correlated positively with the presence of olive groves and with macroecological favourable conditions for rabbits. Our results provide strong evidence that rabbits use motorway verges, which are likely to act as dispersal corridors across landscapes. Additionally, our innovative approach, based on a rabbit warren index, the favourability function and a combination of local and macroecological predictors, could be used in many other areas where rabbits cause crop damage to make fine-scale predictions of high risk stretches and, therefore, where to apply mitigation measures.
