The role of forest clearings and Marantaceae forest on elephant movement at the Odzala National Park was studied by describing and mapping elephant paths. Three types of paths were distinguished based on their direction, length, width, elephant activity and the types of forests they cross. They were called boulevards, foraging paths, and clearing alleys. All paths explored were heavily used. Boulevards are used for travelling over long distances (up to 34 km) and for linking up rapidly favourite sites such as clearings. Foraging paths mainly run through the medium‐density Marantaceae forests which provide elephants with both herbaceous foods and tree fruit. Clearing alleys form a dense network of tracks around clearings. This network could be a result of an anti‐predatory monitoring behaviour of elephants before entering the clearings where they have long experienced heavy poaching. The heavy trampling which results from the elephant activity could contribute to the maintenance of clearings by preventing germination and seedling survival of the numerous seeds dispersed in their dung.
