    Ghana is losing its primary forest, mostly forest reserves at an alarming rate. Secondary forests play a vital role in tropical landscapes, but few studies exist to assess their regeneration pathways and carbon sequestration in Ghana. We sought to find out the regeneration potentials, species diversity and carbon stocks accumulation of off-reserve secondary forests in the Moist Semi-deciduous and Dry Semi-deciduous zones. Four age classes were studied; 0-5, 6-10, 11-15 and 15+ years. Four plots with three replications were used for each age class. Nested plots were chosen; 33 m x 33 m for trees (dbh≥ 5 cm) 10 m x 10 m for saplings (≥1m tall and dbh <5cm) and 2 m x 2 m for seedlings. Age had significant differences in tree (dbh≥ 5 cm) density and basal area between the sites but not on sapling and seedling densities. A total of 129 tree species with dbh ≥5cm belonging to 95 genera and 40 families were identified. Mean Shannon-Weiner diversity index of trees (dbh ≥ 5cm) was 3.6±0.2 and 3.3±0.3 for the Moist Semi-deciduous and Dry Semi-deciduous zones respectively. Both age and forest site had significant effect on aboveground carbon accumulation with age of forest having more significance than climatic conditions. Age of a secondary forest has more effect on the species composition than climate. The secondary forest depicts the characteristic of young growth where the tree densities of most trees are confined to dbh= 5- 10cm in both zones and the potential of rapid recovery of species and carbon accumulation represents an important source of timber and carbon sink. The strong presence of regeneration portrays the potential for carbon sequestration under Reducing Emissions from Deforestation and forest Degradation (REDD+) if secondary forests are managed well in Ghana. Collaborative management of secondary forests with farmers and good forest polices can help Ghana achieve benefits such as timber, woodfuel, and carbon to participate in REDD+.

    In the last 25 years, almost 50 million hectares of primary forest have been lost due to deforestation. Numerous international initiatives such as the Bonn Challenge and the New York Declaration on Forests have set ambitious goals to restore degraded and deforested lands by 2030. Realizing global commitments on forest and landscape restoration (FLR) will require the establishment of billions of trees on millions of hectares of degraded land to address the triple crisis of biodiversity loss, climate change and failing food systems. A significant amount of FLR will require tree planting or increasing tree cover in production landscapes.

    Large-scale forest landscape restoration (FLR) in Africa project: tree-rich landscapes to foster biodiversity, climate change resilience and better livelihoods 2021

    Learn more about the Large-scale forest landscape restoration in Africa project: tree-rich landscapes to foster biodiversity, climate change resilience, and better livelihoods, which is being implemented in Malawi from 2021 to 2024 with support from the Government of Germany through GIZ (Deutsche Gesellschaft für Internationale Zusammenarbeit GmbH). This initiative is part of a larger programme also funded in Cameroon, Kenya, and Rwanda simultaneously. It was designed in support of the Government of the Republic of Malawi’s ambitious target of 4.5 million hectares for restoration under the Bonn Challenge and the AFR100 initiative, and in support of Malawi’s National Forest Landscape Restoration Strategy and National Charcoal Strategy (2017).
