Ideanau-Batoke coastal forest

CMNTIPA042
Ideanau-Batoke coastal forest

Country: Cameroon

Administrative region: Southwest (Region)

Central co-ordinates: 4.09400 N, 9.01300 E

Area: 114km²

Qualifying IPA Criteria

A(i)Site contains one or more globally threatened species

IPA assessment rationale

Although little natural habitat remains, the many rare and threatened species recorded from this area qualify it as an IPA under criterion A(i).

Site description

The Idenau-Batoke coastal forest is a much degraded but unique, very wet, lowland evergreen rain forest strip beneath the boundary of the Mt Cameroon National Park. The area here demarcated includes 114 km2 but this includes approximately 55 km2 designated as palm oil plantations, as well as other cultivated and degraded areas and the settlements of Idenau, Njonji, Bakingili and Cape Debundscha. Populations of several recorded species may already be lost from this site. The site borders three other proposed IPAs, Mt Cameroon National Park, Mokoko-Onge, and Eastern Mt Cameroon. While several species are shared with one or more of these sites, major variation in local climate and topography, as well as the highly threatened status of these other sites, justify its additional inclusion.

Botanical significance

The much larger total area of the Mt Cameroon massif contains the highest recorded diversity of vascular plants in tropical Africa with 2345 species (Cable & Cheek, 1998). It is the only remaining area in Africa with a continuous gradient of vegetation from lowland rainforest at sea-level to subalpine summit grassland (Cheek et al., 1996; Forboseh et al., 2011). Although a large part of this is protected as the Mt Cameroon National Park, the lower slopes and foothills of the massif lie largely outside this zone, are highly threatened, and are botanically very significant due to the rarity of lowland coastal forest and the exceptional climate conditions created by Mt Cameroon. In contrast, many species from the upper areas are more secure from immediate threats and often occur at several other montane sites along the Cameroon volcanic line (Cable & Cheek, 1998).
At least one species, Carappa littoralis (provisionally EN) is considered globally endemic to these remaining scraps of forest. A large proportion of the other listed threatened species, and also several not listed here but included for Mt Cameroon N.P., are found close to the boundary of the National Park which is imperfectly protected and suffering from incursions and border effects. It is unlikely that these populations can survive without efforts to conserve and restore habitat below the N.P. boundary.

Habitat and geology

At over 4000m and by far the highest peak in West and Central Africa, Mt Cameroon has a profound influence on local climate, with great variation in rainfall even along the c.30 km length of this coastal site. Cape Debundscha is considered one of the wettest places on earth, frequently cited as having an average of over 10 m of rain per year based on data from Courade (1974). More recently published long term annual averages extending from 1965-1993 show this reduced somewhat to 9086 mm, with a maximum of nearly 17 m (Fraser et al., 1998). Rainfall is also very high further west at Idenau, with a mean of 8392 per annum. However, at Mokundange at the southeastern tip of this site, only 19 km from Debundscha, the mean per annum drops to 4935 mm. Further inland (outside the site) only 2-3 m falls in the rainshadow on Mt Cameroon's eastern flanks. Rainfall is strongly seasonal throughout the site, with southwesterly prevailing winds driving a wet season peaking in July and August, and then replaced by the dry and dusty northeasterly Harmattan as the intertropical convergence zone moves south. At Mokundange, there is frequently less than 50 mm of rain per month during December and January.
Mean monthly maximum and minimum temperatures vary very little seasonally but minima are a few degrees lower at Mokundange (17.1-18.9 °C) than at Debuschanda (21.6-23.3 °C) and maxima a little higher (27.9-31.7 versus 27.2-30 °C).
Mt Cameroon is the only active volcano in mainland Africa west of the Virunga mountains in eastern DRC. It is formed of alkali basalt and basanite lavas overlying Cretacious to Miocene (or more recent) sediments, which in turn rest on precambrian metamorphic basement rocks (Dereulle et al, 1987; Mathieu et al., 2011). The mountain is considered to be a horst structure by Dereulle et al., 1987): ie. its height is constituted by uplift from below rather than just by accumulation of lava. The age of surface lavas is unclear, with upper Mioecene age estimated by Vincent (1971) and 10 Ma by Fitton (1983) but <3 Ma by Marzoli et al. (2000) and other sources (Mathieu et al., 2011), and recent geological dating suggesting 1-2 Ma (Wembenyui et al. 2020). The unusual nephelinitc lava (Etindite) of Mt Etinde, the southern slopes of which are partly located within this TIPA site, have been dated to 0.65 Ma and are considered approximately simultaneous with Mt Cameroon (Nkoumbou et al, 1995; Ntoumbe et al., 2016) but have previously been estimated to represent an earlier, Miocene, volcanic formation to the main massif (Dereulle et al., 1987; Cable & Cheek, 1998). Seven eruptions were recorded in the 20th century from various Mt Cameroon vents, with a further brief eruption in 2012. Only two of these eruptions, reached this site, the 1922 eruption which flowed down the western slope to meet the sea at Bibundi-Idenau and the 1999 eruption which descended 2500 m down the southern flank to stop just before the sea to the west of Bakingili (Geiger et al., 2016). Recent alluvial soils are also exposed near Idenau (Cable & Cheek, 1999). The soils of this coastal strip, except around Etinde and the insufficiently weathered 20th century lavas, are generally highly fertile and have been targeted for agri-plantations, while further west in the Onge reserve area they are apparently less rich and contain areas of white sand (Cable & Cheek, 1999). Many cinder cones are also present on the southern flanks, a few of these within the site boundaries.

Conservation issues

Much of the coastal strip between the lower National Park boundary and the coast has already been replaced with oil palm plantations where the original vegetation is entirely destroyed (MINFOF & WRI, 2021). Outside the plantations, small-scale agriculture and logging have severely degraded most of the area (Birdlife International, 2021). A hard-surfaced road also runs between Idenau and LImbe, separating the extreme coastal fringe from the mountain and connecting the various settlements. Limbe is now connected to Mokundange and Batoke by continuous urban sprawl which has engulfed former plantation areas. A major new "Limbe Deep Sea Port" is planned at Ngeme, east of Mokundange, which is anticipated to bring 20,000 jobs and stimulate development in the area (Ngah, 2016;. There is also an oil refinery at Mokundange and there is oil prospecting in the area. According to Birdlife International (2021), the best surviving forest of the whole mountain is around Mt Etinde, which has its lower slopes outside the National Park partly in this proposed IPA. Continued development around Batoke and the deep sea port will inevitably further threaten these slopes unless serious conservation efforts are made. The port is also anticipated to increase tourism to the area which, if managed well, could be positive for conservation (Olsen et al., 2001). The DFID and German Government funded Mount Cameroon Project, established in 1994, funded development projects in the area in collaboration with MINEF under a Participatory Biodiversity Conservation Strategy. The proposed IPA area incorporates the Bakingili community forest, established in 2000. REDD+ initiatives have been developed elsewhere around the mountain but apparently not in this area (Awono et al., 2014). Native reforestation efforts within exhausted palm oil plantation zones could be investigated and could be worthwhile because of the unique climate conditions; such projects have been implemented elsewhere on the mountain (ERUDEF, 2021; Truscott, 2021).

Ecosystem services

The area has great potential for ecotourism which could be increased if coastal forests were able to regenerate. Landslides and flooding are a risk to local communities and are mitigated by forested slopes (Payton, 1993; Thierry et al., 2008; Mathieu et al., 2011). The site would previously have helped support the rich fauna of the area but its value has been greatly diminished in this respect.
