Lomami

Lomami National Park, formally established in 2016, is one of the world's newest national parks and protects a vast tract of primary lowland rainforest in the Tshopo and Maniema provinces of the Democratic Republic of the Congo, straddling the Lomami River. Covering approximately 8,880 square kilometres of core zone (with an even larger buffer zone), the park was established following a scientific expedition in 2007 that discovered a new species of monkey—the lesula (Cercopithecus lomamiensis)—in the area, one of the first new primate species described in Africa in 28 years. The park protects some of the most intact and least-surveyed primary forest remaining in the Congo basin.

Lomami's wildlife is remarkable for its endemism and the presence of species rarely encountered in conservation-accessible parks. The lesula monkey, described as new to science in 2012, is endemic to the central Congo basin and occurs within the park. The bonobo (Pan paniscus)—the most endangered of the great apes and found only in the DRC—has significant populations in Lomami. Forest elephants range through the park. The TL2 (Tshuapa-Lomami-Lualaba) landscape, which Lomami anchors, holds six species of primates including the elusive dryas monkey. Okapi are present. The river systems hold Congo dwarf crocodile and numerous endemic freshwater fish species.

Lomami protects primary lowland Congolian rainforest, one of the most biologically diverse but least studied forests on Earth. The tree canopy rises to 40–50 metres, dominated by Gilbertiodendron dewevrei (limbali), a large leguminous tree that can form nearly monodominant stands covering hundreds of square kilometres. Other canopy trees include Cynometra alexandri, Pericopsis elata, and various Brachystegia species. Understorey diversity is extraordinary, with dense communities of herbaceous plants, ferns, and the world's most diverse African orchid flora. The forest floor is carpeted in leaf litter and traversed by small streams harbouring specialist aquatic plants.

Lomami lies within the Congo Craton, the ancient Precambrian basement that underlies the Congo Basin. The park terrain is gently undulating lowland peneplain at elevations of 400–700 metres, with the Lomami River cutting through ancient laterite soils. The geology is dominated by deep tropical weathering profiles—laterite and ferricrete—that overlie Precambrian basement rocks. The Congo Basin itself is a structural depression that has accumulated sediments for millions of years, and Lomami is situated on its eastern margin. The Lomami River is a significant tributary of the Congo River, flowing northward through the park before joining the Congo.

Lomami has a humid equatorial climate with high temperatures and rainfall year-round. Annual precipitation exceeds 1,700 millimetres, distributed across two wet seasons (September–December and March–May) separated by two shorter dry periods. Temperatures average 24–27°C with little seasonal variation. Humidity is constantly high, creating the hot, moist conditions that sustain the primary rainforest. Dry season conditions are relative rather than absolute—rain still falls during the 'dry' months, just at reduced frequency. The equatorial position means solar radiation is intense year-round, driving high rates of plant growth and forest productivity.

The central Congo basin has been inhabited by forest-dwelling peoples—including various Mongo, Luba, and Tetela communities—for thousands of years, practicing shifting cultivation and hunting-gathering in the forest. The remoteness of the region means it was little affected by the early colonial rubber exploitation that devastated more accessible Congo forest areas. The Lomami River was a route used by Arab slave traders in the late 19th century, and the area was incorporated into the Belgian Congo colony following the end of the Arab-Swahili trade. The sparse human population of the forest interior reflects the genuine wilderness character of the central Congo basin.

Lomami's path to national park status began with the 2007 scientific expedition led by John Hart and Terese Hart of the Wildlife Conservation Society, which entered the 'TL2' region—named for the three river boundaries of Tshuapa, Lomami, and Lualaba—for the first time by conservation biologists. The discovery of the lesula monkey galvanised international support for protecting the area. A consultative process with local communities resulted in a jointly developed park proposal that was formally gazetted by the DRC government in 2016. The Harts and Wildlife Conservation Society established the Lomami National Park management framework with ICCN, with particular attention to community benefit-sharing.

Lomami is a wilderness scientific and eco-tourism destination rather than a conventionally developed park. River travel by pirogue (dugout canoe) along the Lomami River is the primary access and exploration mode. Wildlife watching from river and forest camps focuses on bonobo viewing in areas where communities of these great apes have been located near the riverbanks. Lesula monkey observation is possible but requires expert guides with local knowledge. The park's primary appeal is the experience of genuinely untouched primary Congo basin forest—one of the last places on Earth where such large-scale primary forest wilderness survives.

Lomami is extremely remote and requires expedition-level logistics. Access is typically by light aircraft from Kindu (Maniema province capital) or Kisangani to rough airstrips near the park, followed by river travel by pirogue. There are no tourist facilities within the park; visitors must be entirely self-sufficient. The Wildlife Conservation Society and Lomami National Park management can arrange guided expeditions for researchers and specialist eco-tourists with considerable advance notice. Travel in the region requires security assessment given the broader instability of eastern DRC.

Lomami's conservation depends on maintaining the community support structures built during the park establishment process, as the surrounding villages are critical partners in anti-poaching and boundary management. The park staff includes community rangers recruited from local villages. The principal threats are bushmeat hunting, artisanal mining in the buffer zone, and the potential for agricultural encroachment as population pressure increases. The Wildlife Conservation Society and ICCN continue to support park management, and a community benefit-sharing fund distributes income from any tourism to neighbouring villages, creating tangible economic incentives for conservation.
