“…Similar results have been obtained in other sacred forests in Cameroon [21,31,34,35,36]. Moreover, these results differ from those of Mbaiyetom et al [37], who found a preponderance of large-diameter individuals in the tree park in the Sudanian zone of Tchad [38][39][40].…”

Cameroon has a diversity of forest ecosystems, including sacred forests that have been preserved until now by traditional laws. The aim of this study was to characterize the vegetation of two sacred forests in the Western Highlands and to estimate the quantities of carbon stored by these forests. The inventories were carried out in 24 quadrats measuring 30 m x 30 m installed in the Bansoa and Baloum forests according to their surface area. Individuals with a diameter of 10 cm or more at breast height (1.30 m from the ground) were measured. Phytodiversity was assessed using the Shannon and Simpson indixes. The quantities of carbon stored by the sacred forests were obtained using allometric equations developed by other researchers and appropriate to the tropical zone. Overall, 50 species in 31 genera and 25 families were recorded. The diversity index values are low. They range from 1.47 to 2.52 bits per plot for the Shannon index, and from 0.70 to 0.91 for the Simpson index. Markhamia lutea and Cola acuminata are the most frequent and abundant species in the study area. The densities of individuals per hectare are 368 individuals/ha at Bansoa and 416 individuals/ha at Baloum and the basal area varies from 32.37 m2/ha to 38.44 m2/ha. The shrub layer dominates in both forests. Of the species recorded, 03 are Vulnerable and 02 are Endangered. Carbon sequestration was 286.84 t C/ha at Baloum and 232.44 t C/ha at Bansoa, with CO2 uptake of 1052.12 t CO2/ha and 853.55 t CO2 /ha respectively. The results of this study show that despite their small size, sacred forests play a significant role in the conservation of plant diversity and also help to reduce greenhouse gases in nature.

“…Similar results were recorded by Ngougni [9] and Tiokeng [10] in the sacred forests of Menoua and Bamboutos. The Burseraceae are also among the most important families; their presence in these sacred forests is a sign that they are the result of dense Atlantic forests [34,35,8]. There is also a relative abundance of the genus Cola sp.…”

The vegetation of West Cameroon has been almost entirely destroyed, and the only remaining forests are mostly so-called "sacred" forests, which play a role in regulating the climate. The aim of this study was to assess the wood diversity and carbon stored by sacred forests in the Ndé division. The inventories were carried out on 34 plots of 900 m2 each. To do this, all woody individuals with a diameter ≥ 10 cm at 1.30 m above ground level were counted. Floristic diversity was assessed using diversity indices. Allometric equations were used to estimate biomass in order to deduce the carbon stored by these forests. At the end of the surveys, 77 species belonging to 57 genera and 32 families were recorded. Dracaena arborea and Cola sp. were the most common species (64.71% and 94.12% respectively). The density of individuals varied from 299 stems/ha to 341 stems/ha in the forests studied. Basal area varied from 42.19 m²/ha to 53.28 m²/ha. Shannon index values are low in both forests (around 2±0.38 bit), indicating low specific diversity at the sites studied. Carbon values ranged from 286.89 tC/ha to 215.67 tC/ha in these sacred forests. Cola sp. and Dracaena arborea recorded the highest carbon values. Of the species recorded, 03 are vulnerable. This study reveals the importance of sacred forests for the conservation of biodiversity and their capacity to store carbon in order to contribute to the mitigation of greenhouse gases.

“…In Cameroon, scientists have studied these forests with interest, particularly in the Western Highlands of Cameroon. A number of studies have shown that these forests have been preserved thanks to prohibitions passed down from generation to generation (Tiokeng et al, 2007;Noumi, 2012;Noumi & Tiam, 2016). The species richness of woody plants in these forests is generally low, with densities of individuals per hectare sometimes comparable to those regularly observed in other dense forests (Tiokeng, 2024;Tiokeng, 2020).…”

The sacred forests of the Western Highlands Cameroon are, like other forests, a reserve of plants and genes, both known and unknown. They are privileged places for communication with ancestors. They provide significant environmental and socio-economic benefits; despite the pressure they are increasingly coming under. The aim of this study is to categorise the different uses of the sacred forests of Bafou, Baleveng and Bamendou, and then to assess the carbon stock of the woody plants in these forests. A survey form was used to record the various benefits derived by local people from the sacred forests. Individuals were counted in 30 m x 100 m plots. All individuals with a diameter ≥5 cm at 1.30 m above ground were considered. Carbon sequestered by forests was estimated using the non-destructive method. The study shows that the traditional laws protecting these forests are increasingly being violated by local people. These forests are cultural properties for the village and provide the local population with a variety of products. The most frequently cited uses are firewood, food products, medicinal plants and sacrifices. A total of 54 species, 47 genera and 29 families have been identified. Of these species, around 40.35% are used in one way or another by local people. The values of carbon sequestered by these forests vary from one forest to another and according to the type of equation chosen. The Bamendou sacred forest recorded the highest value, 443.9 t C /ha and 287.79 t C /ha respectively, using the equations of Djomo et al. (2010) and Fayolle (2013). This work presents the benefits of sacred forests for local populations. Management strategies for these forests should be strengthened by the State to ensure more sustainable conservation of this rich heritage.
