ArticlePlant diversity and regeneration potential in forest protected areas of Sierra Leone
XV World Forestry Congress, 2-6 May 2022
2022Also available in:
No results found.Protected areas (PAs) around the globe are considered a reservoir for biodiversity conservation and an engine for ecosystem function and services. The regeneration potential of tropical forests in Protected Areas (PAs) is crucial to plant diversity and conservation, amid climate change uncertainties in the 21st century. The current status and future sustainability of PAs in Sierra Leone is uncertain and may lead to the risk of species extinction in the near future. To close this gap, we assessed the seedlings, saplings, and trees species diversity, abundance, richness and regeneration status of four PAs across Sierra Leone. We sampled 60 quadrats in total with each having a dimension of 20m × 20m. We found only a few new species with good regeneration potential in all the forest PAs we assessed, indicating that the resilience of these forests are quite low in the face of degradation. Plant diversity index and soil factors were positively correlated, indicating that a decrease or increase in soil physical and chemical properties could affect speciation. The diameter class distribution shows that the majority of plant sizes fall within the 0-30cm category. The plant species with the highest importance value index (IVI) were Uapaca guinensis (34.71), Heritiera utilis, (37.93), Guibourtia. copallifera (115.50) and Phyllocosmus africana (37.24) respectively. The results showed that the plant diversity status of forest PAs in Sierra Leone is at a crossroad. It recommended that strategic planning and forest enrichment policies be put in place to mitigate future forest exploitation.

ArticleREFLOR-CV: Adaptation of local communities to the impacts of climate change in Cabo Verde through restoration of wooded areas
XV World Forestry Congress, 2-6 May 2022
2022Also available in:
No results found.Cabo Verde (CV), a small island developing state, is one of the most vulnerable countries to the impacts of climate change, where drought and highly variable and concentrated rains constitute the main climate change threats. In this context, land degradation resulting from prolonged dry spells, surface runoff and erosion, and indiscriminate land use have been affecting land productivity, while shrinking native vegetation to microrefugia sites. The project Building Adaptive Capacity and Resilience of the Forestry Sector in Cabo Verde (REFLOR-CV) focuses on the restoration of wooded and silvopastoral areas in three islands of the archipelago. The goal is to increase the resilience of local communities by promoting the conservation of habitats and biodiversity, favoring soil conservation and the replenishment of groundwater, as well as supporting livelihoods through valorization of non-timber forest products. The project uses a knowledge-based approach that includes capacity building and the development of forest co-planning and co-management instruments, enabling participation and transparency in decision making. For the development of island and stand-level planning instruments, an agency approach is employed to ensure equity and accountability in the prioritization and implementation of nature-based solutions and restoration measures. During this process, locally preferable endemic, native, or adapted woody species are produced in communitarian nurseries and in household orchards. Then, after a biophysical-climatic suitability of potential sites is technically analyzed and conveyed, community-level decisions on site-specific land interventions are defined and implemented. The results include ~ 800 ha planted in 40 patches and ~300 000 plants fixed, including 9 different native and endemic species. There are ~600 men and ~900 women directly involved in soil conservation and plantation activities, with ~50 technical staff capacitated. The calculation of the direct contribution of these results to the NDC of CV will be provided.
