Okapi conservation


Because of its shy nature and the challenges of fieldwork in the forests of the Democratic Republic of Congo (DRC), obtaining accurate and up to date information on the okapi - or 'forest giraffe' - has been a major conservation challenge. In 2010, ZSL started a collaborative effort to carry out the first range-wide conservation status review of this little-known but iconic species. This research led to the reassessment of the okapi as Endangered on the IUCN Red List of Threatened Species and laid the foundations for the development of the first okapi conservation strategy, which outlines the conservation measures to be taken to ensure the persistence of this species in the future.

Work in DRC

Okapi were first discovered (by a ZSL fellow) in Virunga National Park in eastern Democratic Republic of Congo: the oldest and most biodiverse national park in Africa. Virunga was the first African protected area listed as a UNESCO natural World Heritage Site, but as a result of civil conflict was re-listed as a World Heritage Site in Danger in 1994. Since 2001, ZSL has worked to rebuild the capacity of the Congolese conservation authority, ICCN, to restore the long-term integrity of the park and other protected areas in the okapi’s range. Sadly, as a result of political unrest across the okapi's range and tragic attacks on staff and okapi in the Okapi Wildlife Reserve where we were working at the time, ZSL was forced to suspend operations on the ground in DRC in 2013, but continues to support okapi conservation efforts as co-host of the IUCN SSC Giraffe and Okapi Specialist Group (see below).

Okapi in Virunga

In 2008 ZSL and the Congolese conservation authority, ICCN, surveyed the Watalinga forest in northern Virunga National Park and reconfirmed the presence of okapi in the park, not officially recorded since 1959. In doing so, the team captured the first ever camera trap images of a wild okapi. ZSL investigated the threats faced by the Watalinga okapi population and concluded that its local extinction was likely unless immediate conservation action was taken. A rehabilitated road cutting through the park had allowed increased pressure from deforestation and hunting for meat and skins.

Leading range-wide okapi conservation

In 2010 ZSL and ICCN launched a major collaborative project to assess the status of okapi across its range and develop a strategy for its conservation. Collating historic and current okapi survey data and carrying out genetic analyses has allowed us to understand the distribution, abundance and threats to okapi across its range. This has facilitated the development of new tools to monitor okapi, underpinned the reassessment of the okapi as Endangered on the IUCN Red List and enabled the development of the first ever okapi conservation strategy and status review, guiding actions for a ten-year period from 2015-2025. We also trained staff from ICCN and partner organisations to build capacity for future okapi management. A workshop was held in May 2013 in DRC with multiple stakeholders from across the okapi’s range to develop this strategy.

Studying okapi genetics

Joint ZSL Institute of Zoology and Cardiff University PhD student Dave Stanton carried out a pioneering study of okapi genetics as part of ZSL's range-wide okapi conservation project, using current and historic dung, skin and bone samples collected with the help of museum and field partners across the okapi's range. He found that okapi are genetically both distinct and diverse, probably as a result of periods of forest fragmentation and expansion in the Congo Basin in the ancient past. His work also confirmed the presence of the okapi on the west bank of the Congo river, provided new information on individual movements, barriers to dispersal and ecology of okapi, and uncovered the relatedness between captive okapi and to those in the wild. Finally, he found that field teams often confused okapi dung with that of the bongo, which has serious implications for the accuracy of dung-based okapi population surveys! Such insights are invaluable in informing future conservation efforts.  


Safeguarding okapi and forest elephants in the Okapi Wildlife Reserve

The Ituri Landscape harbours the largest remaining population of both okapi and forest elephants in DRC. Unfortunately, even in its namesake core protected area, the Okapi Wildlife Reserve (RFO), populations of both species are declining and threatened by poaching and the impacts of illegal mining.  Following a brutal attack by armed poachers on the Reserve headquarters in 2012, killing 7 people and all 14 okapi housed there and destroying infrastructure and equipment, ZSL is working with the Wildlife Conservation Society to help ICCN restore the integrity of RFO and implement SMART, a protected area management system which enables managers to put rangers where they are most needed and to monitor the impacts of their patrols so they can adapt patrol effort accordingly.

IUCN SSC Giraffe and Okapi Specialist Group

In March 2013 the IUCN SSC (Species Survival Commission) Giraffe and Okapi Specialist Group was formally established. The aim of the group is to attract and strengthen international support for giraffid conservation, provide technical advice on giraffe and okapi and provide an official forum to support strategies to conserve these species. The two co‐chairs for the group are Dr Julian Fennessy from the Giraffe Conservation Foundation (for giraffe) and Dr Noëlle Kümpel from ZSL (for okapi).

Project information

Key species

The okapi (Okapia johnstoni), a close relative of the giraffe, is endemic to the tropical forests of central and north-eastern Democratic Republic of Congo (DRC). It is listed as Endangered in the IUCN Red List (following an assessment led by ZSL in 2013). ZSL's relationship with the okapi dates back to its official discovery in 1901 by a ZSL Fellow. The size of a small horse, the ‘forest giraffe’ has a chocolate brown coat with distinctive white stripes on its legs and hindquarters, and a 30 cm long, purplish-blue tongue adapted for browsing trees like its better-known cousin.

Partners and sponsors

ZSL is leading this range-wide okapi project on behalf of ICCN (Institut Congolais pour la Conservation de la Nature), and relies on the efforts of multiple partners working across the entire okapi range and beyond, including the Okapi Conservation Project, Wildlife Conservation Society, Lukuru Foundation and University of Cardiff.

The project has been generously funded by the UK government's Darwin Initiative, the US Fish and Wildlife Service, the Mohamed bin Zayed Species Conservation Fund, the European Commission, the Natural Environment Research Council, SOS – Save Our Species and Fondation Segré.

The okapi was first discovered by the western world by ZSL fellow, Sir Harry Johnston, in 1901 but what else do we know about this extraordinary and shy creature?


  1. The only place in the world that you can find a wild okapi is in the dense tropical rainforests of the Democratic Republic of Congo. It is hardly surprising then that they are the country's national animal and even feature on local bank notes.
  • Okapis closest living relative is the giraffe. As its slightly smaller, shyer, rarer cousin in the giraffid family it is often known as the ‘forest giraffe.’ 
  • The okapi tongue is purplish-black, prehensile and reaches 30cm - that's long enough to lick its nose, ears and even its eyes. The dark colour protects the tongue from getting sunburnt as it curls around branches and vegetation, pulling it into its mouth to eat.   
  1. Zebra-like stripes on the okapi’s legs and bottom are thought to be a key part of its fantastic camouflage as well as a way to help the young to follow their mothers through the thick forests.  Being unique to each individual, these stripes also help conservationists to monitor their activities and population size by capturing images of the animals on remote ‘camera traps’
  • Male okapi have furry horns on their heads called ossicones, a bit like the giraffe’s horns, though these are found on both male and female giraffe.

The threats facing the okapi include poaching, deforestation, armed conflict and illegal mining

  • Okapi have large ears they can point in different directions to detect dangerous predators such as the leopard.
  1. Okapi are shy and usually harmless herbivores threatened by deforestation, poaching, armed conflict and illegal mining that has caused their population to drop dramatically in recent years. Having reassessed the species as ‘Endangered’, ZSL worked with IUCN, ICCN (the Congolese conservation authority) and a wide range of other partners to develop the first ever long term Okapi conservation strategy aimed at keeping the Okapi from extinction.
  • Until recently there were thought to be between 10,000 and 35,000 okapi left in the wild. However, as this wide range suggests, it is very hard to know for sure as they are so difficult to survey in the wild, though experts estimate that their number has halved in the past 25 years.
  • The first wild photos of the okapi were taken by ZSL camera traps in 2008, reconfirming the presence of the okapi in the very spot where the species was first described, by ZSL over 100 years before.

Okapi camera trap image

  • As you may have gathered, okapi are incredibly hard to see in the wild.  Even for field researchers lucky enough to spend time in the okapi’s native rainforests, the best chance of seeing a real, live okapi is probably in a zoo like ZSL London Zoo!
