<!-- INSTRUCTIONS FOR COMPLETING Site INFORMATION
- Wiki site pages contain information in paragraphs of text, tables, keyword lists, and images
- Text paragraphs and images are not restricted, so text format and images can be chosen as desired.
- Tables and keyword lists are extracted as data, and so have the following restrictions:
1) Table structure cannot be changed
2) Keyword format should not change, i.e. they are comma separated lists, not bullet points or numbered lists.
3) Keywords must be taken from the list of permitted words, or added to the list of permitted keywords. A link to the keyword list page is found adjacent
to the relevant table or keyword list. This ensures that the same keyword always refers to the same concept, e.g. Everybody uses "Industrial mining",
rather than several keywords such as "Industrial mining", "Large-scale mining", and "Mining".

= Summary = <!-- An overview of the site, with a one sentence overview of each of the following sections. can include a site map -->

* Western chimpanzees ([https://www.iucnredlist.org/species/15935/17989872 ''Pan troglodytes verus'']) are present in East Nimba Nature Reserve.
* It has been estimated that 28 individuals occur at the site.
* The chimpanzee population trend is stable.
* This site has a total size of 135 km².
* Key threats to chimpanzees are habitat loss due to iron ore mining and shifting agriculture, and poaching.
* Flora and Fauna International, and Conservation International support Liberia’s Forest Development Authority in the protection of the site and implementation of conservation activities, focused mainly on education and awareness.
* The site borders Mount Nimba Strict Nature Reserve in Guinea and Ivory Coast.


= Site characteristics = <!-- A paragraph summary of physical and geographic aspects of the site, and a table of key information -->

East Nimba Nature Reserve is located in the north of Liberia, bordering Guinea and Cote d’Ivoire. East Nimba Nature Reserve was established in 2003 and covers part of the Mount Nimba Mountain range, which spans across Liberia, Guinea, and Cote d’Ivoire. The reserve borders Mount Nimba Strict Nature Reserve (UNEP-WCMC and IUCN 2019). In addition to the Western chimpanzee, other endangered and endemic ([http://www.liberianfaunaflora.org/east-nimba-nature-reserve-ennr species]) inhabit the site, including Jentink’s duiker (''Cephalophus jentinki''), Nimba otter shrew (''Micropotamogale lamottei''), Nimba flycatcher (''Melaenornis annamarulae'') and Nimba toad (''Nimbaphrynoides occidentalis'').

= Ape status = <!-- a text overview of ape status (population sizes, trends etc), followed by a table of specific surveys and results -->

The population in East Nimba Strict Nature Reserve has been estimated at 28 individuals (WCF unpubl. data). In addition, chimpanzee presence in the reserve has been recorded by the nationwide survey teams (Tweh et al. 2014). However, based on two unpublished datasets from 2010 (WCF unpubl. data) and 2014 (PANAF unpubl. data) Kühl et al. (2017) estimated a stable population size for this site.

= Threats = <!-- a text overview of threats, followed by a table of key threats -->

Part of the nature reserve was severely degraded due to iron ore mining that occurred between 1962 and 1989 (CILSS 2016). The site has also been severely affected by deforestation; between 1974 and 2014, about half of its forest cover was lost (CILSS 2016). Bushmeat hunting in the area is also a key threat to chimpanzees (Bene et al. 2013).

= Conservation activities = <!-- a text overview of conservation activities, followed by a table of key activities -->

Liberia’s Forestry Development Authority (FDA) is responsible for the protection and long-term management of East Nimba Nature Reserve. The site lies within the concession of an iron ore mining company, Arcelor Mittal Liberia (AML). In 2015, AML funded a ([https://www.fauna-flora.org/projects/implementing-effective-management-east-nimba-nature-reserve joint project]) with Flora and Fauna International to ensure the effective management of the site and provide technical support and capacity building (FFI). Conservation International (CI) also contribute to the protection of the site by providing environmental education and conservation awareness in nearby communities (FFI). As part of their livelihood improvement project, CI recruit Frontline Conservationists from local communities, who patrol and monitor the forests in exchange of a monthly stipend (CI 2016).
