We assessed the role of biological corridors for plant dispersal under climate change at a regional scale with limited knowledge on species traits (i.e., on tropical ecosystems) and uncertain future climate scenarios. For this purpose, we developed a cellular automata model to simulate plant dispersal and used the Mesoamerican Biological Corridor (MBC) as a test base. We found that important biological corridors have relatively large areas and gradients in altitude, latitude, and longitude and that only the fastest species can keep up with the expected change in climate. We conclude that the spatial assessment of the vulnerability of protected areas and the role of corridors in facilitating dispersal can help conservation planning under a changing climate.
