African wild suids living in forests have been poorly studied, and some species such as the giant forest hog (Hylochoerus meinertzhageni) – one of the largest species of wild pigs in the world – are disappearing at alarming rates. Of particular concern are the eastern Africa populations that are endangered by habitat encroachment and illegal hunting. Here, we present results of the first ecological study on this species in the Kibale National Park, a mid-elevation, tropical forest in western Uganda. The goal of our research was to determine group’s movement patterns, group size and structure, habitat use, and foraging patterns. At intermittent periods over 5 years, we tracked a group of this species using handheld GPS, and for 2 years we deployed automated camera traps in salt licks and bathing places. Home range of the group of giant forest hogs was estimated at 11.2 km² (kernel density estimator at 99%) with a core area of 2.4 km² (kernel density estimator at 50%). Areas with dense bushes and sparse trees surrounded by mature forests were their favorite habitat where they feed on the herbaceous plants and rest in shady areas of approximately 5 × 5 m located under the densest thickets called “sleeping sites.” Giant forest hogs were captured on camera traps 7893 times within 141 independent events that showed that group size is highly variable and ranges from 3 to 11 individuals with occasional sightings of solitary individuals, usually subadult males. Occupancy rate value was medium (ψ = 0.778; SE = 0.01), and the species presented a low detection probability (P = 0.172; SE = 0.01). Large groups are composed of a dominant male, one or two additional males, several adult females, and up to four juveniles. Conservation of this species in eastern Africa requires the protection of forest ecosystems and associated mosaic of habitats with dense bushes and open gaps surrounded by mature forest.
