Okapi: The Forest Ghost of the Congo Basin
A single living species connects modern wildlife to the ancient lineage that produced the giraffe — yet most people have never heard its name. The okapi (Okapia johnstoni) inhabits only the dense rainforests of the Democratic Republic of the Congo, where its secretive habits kept it unknown to Western science until 1901 [Sclater 1901; Lankester 1901]. Today, this Endangered species faces mounting pressure from artisanal mining, illegal trade, and armed conflict. This article introduces the okapi's biology, explains the forces threatening its survival, and describes the science-driven partnerships working to secure its future.
Biology and Identification
The okapi is the sole living member of genus Okapia and belongs to family Giraffidae — placing it as the closest living relative of the giraffe, not the zebra despite superficial resemblance [Hassanin et al. 2012]. The black-and-white horizontal stripes on its haunches and upper legs have long prompted popular comparisons to zebras, but okapis and zebras share no close common ancestry — they belong to entirely different mammalian orders [Hassanin et al. 2012].
Adults stand roughly 1.5 meters at the shoulder; females typically weigh between 225 and 350 kilograms and males between 200 and 300 kilograms, making females the larger sex on average [SDZWA]. The body coat is a rich chestnut-brown that blends with the dappled light of the forest understory. Males carry short, skin-covered ossicones structurally homologous to those of giraffes.
One of the okapi's most remarkable anatomical features is its prehensile tongue, which the animal uses to clean its own eyelids and ears — an adaptation well-suited to a densely forested environment [SDZWA]. As a browser, the okapi selects specific leaves, shoots, bark, and fruiting bodies rather than grazing indiscriminately.
Okapis are predominantly solitary outside of brief mating associations. Females raise a single calf after a gestation of approximately 14 to 15 months; the calf may remain with the mother for up to a year [SDZWA]. Scent glands on the feet deposit secretions during travel, a behavior documented in territorial marking contexts [SDZWA].
Habitat and Range
The okapi is a strict forest specialist found only within the Democratic Republic of the Congo [IUCN 2015]. Its range is concentrated in the lowland and lower-montane tropical rainforests of the Congo Basin, where closed-canopy cover, layered understory browse, and proximity to water sources are all present. The species does not persist in degraded or fragmented forest patches; intact forest extent is the primary determinant of local population viability [AJE 2025].
Key refugia occur within several of the DRC's protected areas, including the Okapi Wildlife Reserve (a UNESCO World Heritage Site) and multiple national parks in the country's north and east. In accordance with NRWL sensitive-species protocols, specific site coordinates and subpopulation localities are not disclosed here.
Conservation Status
The okapi is currently listed as Endangered on the IUCN Red List of Threatened Species, reflecting an estimated population decline exceeding 50 percent over approximately two decades [IUCN 2015]. This represents a significant change from the species' earlier classification as Near Threatened and reflects the acceleration of the pressures described below.
In November 2025, the okapi was uplisted to CITES Appendix I at CoP20 in Samarkand — the highest level of international trade protection, prohibiting all commercial cross-border trade in the species or its parts [CITES 2025]. The Wildlife Conservation Society (WCS) and the DRC's Institut Congolais pour la Conservation de la Nature (ICCN) were among the primary advocates for this uplisting [WCS 2025].
Wild population estimates vary considerably given the difficulty of surveying dense forest. Recent analyses estimate fewer than 15,000 individuals remaining — down from an estimated 40,000 in earlier population surveys [AJE 2025; IUCN 2015].
Threats
Artisanal and small-scale mining has been identified as the dominant driver of okapi population decline since 2009. Regression analysis attributes approximately 98 percent of the population reduction over that period to habitat destruction associated with mining operations, through a strong inverse relationship between the number of active mining sites and remaining primary forest cover [AJE 2025]. Mining operations fragment and destroy forest, displace wildlife, and introduce associated human settlement, subsistence hunting pressure, and access infrastructure into previously intact areas.
Illegal wildlife trade compounds these pressures significantly. Since 2019, export of okapi parts — including skins, meat, bones, and fat — has been documented crossing DRC's borders into neighboring countries. Investigations suggest products linked to approximately ten individuals per month have been smuggled internationally, though the actual scale is difficult to verify independently [WCS 2025]. The CITES Appendix I listing directly targets this trade route at the international level.
Deforestation and logging, driven by charcoal production, commercial timber extraction, and agricultural encroachment, continue to reduce total forest cover and fragment the landscape in ways that isolate subpopulations from one another [AJE 2025].
Armed conflict and civil insecurity in eastern DRC impede ranger patrols and conservation fieldwork, allowing illegal extraction and poaching to proceed unchecked in areas that are formally protected [OCP 2025]. The June 2012 armed attack on the Epulu research station within the Okapi Wildlife Reserve — which killed 14 captive okapis and six people including two wildlife rangers, and destroyed more than a decade of conservation infrastructure — illustrates how directly insecurity translates into conservation losses [Mongabay 2025].
What's Being Done
The Okapi Conservation Project (OCP), in partnership with the ICCN, coordinates the most sustained ground-level conservation program for the species. In 2024–2025, OCP deployed camera trap arrays that confirmed continued okapi presence alongside co-occurring threatened species such as chimpanzees and African forest elephants, providing the first systematic occupancy data from target sectors in several years [OCP 2025].
OCP also operates an agroforestry program that distributed more than 115,000 seedlings to more than 4,000 farming households in 2024, reducing pressure on intact forest by improving agricultural productivity on already-cleared land. Over 800 community vegetable gardens were established in the same period, directly improving food security for households adjacent to the reserve [OCP 2025]. An intelligence network of community informants supports anti-poaching operations in areas where ranger access is constrained.
In a significant milestone, an okapi was returned to the Epulu research station in February 2025 — the first animal at the facility since the 2012 attack [Mongabay 2025; OCP 2025]. Reestablishing a managed facility enables veterinary research, behavioral observation, and community education programs that feed directly into wild population management.
The IUCN SSC Giraffe and Okapi Specialist Group coordinates international scientific assessment and supports DRC national authorities in developing evidence-based management plans [IUCN SSC 2025]. WCS provides technical support and ranger capacity building for ICCN units operating across remote forest areas [WCS 2025].
How Readers Can Help
- Learn and share accurately. Public awareness outside the DRC shapes the market demand that drives illegal wildlife trade. Sharing verified, source-linked information about the okapi's endangered status is a direct contribution to reducing that demand.
- Engage on supply-chain policy. Artisanal mining of gold and coltan — minerals in consumer electronics — is the single largest measured driver of okapi habitat destruction [AJE 2025]. Constituent contact with legislators and trade regulators about mineral supply-chain due diligence laws (such as the EU Conflict Minerals Regulation and U.S. Dodd-Frank Section 1502) has documented policy effects.
- Advocate for forest-protection legislation. Timber import regulations, deforestation-linked commodity standards, and foreign aid provisions for conservation all affect the habitat pressures on Congo Basin species. Contacting elected officials and regulatory agencies in consumer countries is an actionable step.
- Participate in citizen science. Contributing verified biodiversity observations to platforms such as iNaturalist builds the global datasets that scientists use to model habitat connectivity and climate vulnerability — including for species in regions where direct fieldwork is logistically difficult.
- Choose certified materials where available. Fairtrade Gold and FSC-certified timber represent third-party verification of responsible sourcing. Consumer purchasing decisions aggregate into market signals that affect extraction practices in forest landscapes.
- Support AZA-accredited zoos. Institutions accredited by the Association of Zoos and Aquariums participate in the okapi Species Survival Plan (SSP), fund field conservation directly, and maintain the genetic and behavioral research that informs reintroduction planning. Membership and educational engagement at accredited facilities supports this work.
