Dzanga National Park mammal records (Central African Republic, 2025)

Site Summary: In March 2025 I visited Dzanga Bai and Bai Hokou, both in Dzanga National Park, with Ian Thompson. The +20 mammal species seen on four days in the park (excluding the buffer zone) included Forest Elephant, Bongo, Giant Forest Hog, Agile Mangabey and Noack’s Round-leaf Bat. My reptile records for Dzanga-Sangha are reported separately HERE and included Gonwouo’s Mabuya (Trachylepis gonwouoi).

C.  Site Information

Dzanga NP and the buffer zone are within the Dzanga-Sangha Protected Area, which includes various national parks and buffer zones.

Dzanga Bai:
Bais are natural open wetlands with mineral salts and are frequented by the larger mammals. Dzanga Bai, in the Dzanga sector of the Dzanga-Ndoki National Park, is especially significant as up to 200 forest elephants might be present. The bai is about 500 meters long and 200 meters wide. WWF have constructed a large, covered platform at which you can camp overnight. From Doli Lodge it is a 45-minute drive to the Dzanga Bai Camp and a 40-45 minute walk, with guides, across a creek and into the rainforest, but longer if stopping to mammal-watch. On day-visits you have to leave Dzanga Bai by 4 PM, to minimize elephant encounters.
GPS: Dzanga Bai Camp: 2.942253°N 16.352154°E.
GPS: Dzanga Bai Tower: 2.954336°N 16.364109°E.

Bai Hokou:
The Bai Hokou ranger station is about a one-hour drive from Doli Lodge.
GPS: Bai Hokou Camp: 2.859772°N 16.467685°E.
The Saline Tour involves guided walks between the various bais. The Agile Mangabey Tracking Tour is a guided tour to the troop of habituated Agile Mangabeys. Our guides took us to trackers who had already located the troop.

D.  Trip Information

We had two one-night stays at Dzanga Bai (13 and 19 March). We also went on two guided day-trips to Bai Hokou (12 and 21 March); the first was focused on Mangabey Tracking and the second was a Saline Tour / Bai Walk. These trips were all done whilst we were based at Doli Lodge. Costs and logistics for these visits are summarised in my Doli Lodge report here.
Ian Thompson’s report for this trip was posted on mammalwatching.com here (on 6 July 2025).

BBC Earth documentary series: “The Guardians”
Whilst at the lodge we met Mark McClean and Ben Zand who were working on a BBC Earth documentary series called The Guardians. The first episode features Dzanga-Sangha NP and can be seen HERE (on YouTube). Blue Hare Films: “The first episode was produced and directed by Mark and Ben Zand and features Dzanga-Sangha National Park in the Central African Republic. It’s a UNESCO World Heritage Site where the fight for conservation is as complex as the rainforest itself. It celebrates the ranger Modiki (Africa Ranger of the Year 2024), a truly inspiring figure who went from poacher to protector. Through immersive patrols, we witness his powerful transformation and deep commitment to safeguarding the park’s precious biodiversity.”
