“…Tropical forest regeneration is a natural process that is important for the conservation of ecosystems (Hardwick and Elliot 2015). The maintenance of the regeneration potential is essential to ensure the sustainability of silvicultural management, promote forest succession dynamics, and consequently preserve the natural patterns of resilience in disturbed environments (Ackzell 1993;Folke 2006).…”

no genetic differences between stands and no evidence of inbreeding. Genetic clustering identified a single population (K = 1), indicating no genetic differentiation between managed and unmanaged stands. Adult and juvenile individuals of the unmanaged stand were more geographically structured than individuals from the managed one. There was a tendency of coancestry among juveniles at the first class of distance of the managed stand, suggesting a drift of genetic structure possibly caused by management. Understanding early responses to management on genetic diversity and stand structure is a first step to ensuring the effectiveness of conservation practices of tree species. The sustainability of forest management of E. erythropappus on genetic diversity, and more accurately, on spatial genetic structure needs evaluation over time to promote effective conservation of the population size and genetic variability.

“…Consistent with this, Griscom and Ashton (2011) and Mebrat (2015) reported that tree planting can ameliorate poor soil conditions that limit natural regeneration. Holl and Aide (2011) and Hardwick and Elliott (2016)…”

“…Active restoration interventions of highly degraded areas can recover biodiversity and ecosystem services (Brancalion et al, 2016; Latawiec et al, 2016). It aims to accelerate natural regeneration and development processes when the spontaneous establishment of trees is insufficient to create conditions for successful native plant regeneration and forest development (Hardwick & Elliott, 2016; Holl & Aide, 2011). The high cost of active restoration projects (Birhane et al, 2017) than natural regeneration is a very notable constraint, and therefore, financial capacity limits its large‐scale implementation.…”

Land rehabilitation through exclosures has been recognized as a promising practice in the restoration of degraded drylands. This study evaluated woody species density, diversity, cover, and biomass production from three regeneration approaches (EMTs): (1) Naturally Regenerated (ENR) exclosures, (2) exclosures with Soil and Water Conservation Structures (ECNR), and (3) those enriched with exotic and local plant species in addition to SWC structures (ECP) among which empirical evidence of comparisons are lacking for appropriate decision making of which restoration strategy to promote. Primary data were collected from a total of 72 study plots located across transects laid within exclosures and in adjacent grazing areas with similar ecological condition. Interview with 331 households and focus groups was used to further understand the effects. Regression analysis revealed that the mean difference in herbaceous and canopy cover, herbaceous and woody biomass, and woody species density and diversity of the three EMTs was statistically significantly higher than in the adjacent open grazing areas. Moreover, herbaceous biomass in ECP differed significantly from that of ECNR. The results indicated that ENR and ECP equally enhanced the selected vegetation parameters. This is predominantly attributed to the comparable responsiveness of many degraded areas to natural regeneration as they do to active regeneration approaches. Implementation of natural regeneration is suitable for immediate recruitment of strategy in terms of resources, time, and meeting objectives before decisions are made for assisted models of exclosure that require massive campaigns to construct soil and water conservation structures and huge seedling production in the dryland areas.

“…The five least common taxa included in the model (1% of all stems) were Duboscia macrocarpa, Ongokea gore, Zanthoxyllum heitzii, Klainedoxa sp., and Erythrophleum ivorense. Each species was assigned, if possible, into an "early-successional" or "latesuccessional" class based on growth form, available trait data, and habitat class (Whitmore, 1989;Raich and Khoon, 1990;Finegan, 1996;Davies and Semui, 2006;Chazdon et al, 2010;Hardwick and Elliott, 2016).…”

Distinct Community-Wide Responses to Forecasted Climate Change in Afrotropical Forests

et al. 2022

More refined knowledge of how tropical forests respond to changes in the abiotic environment is necessary to mitigate climate change, maintain biodiversity, and preserve ecosystem services. To evaluate the unique response of diverse Afrotropical forest communities to disturbances in the abiotic environment, we employ country-wide tree species inventories, remotely sensed climate data, and future climate predictions collected from 104 1-ha plots in the central African country of Gabon. We predict a 3–8% decrease in Afrotropical forest species richness by the end of the century, in contrast to the 30–50% loss of plant diversity predicted to occur with equivalent warming in the Neotropics. This work reveals that forecasts of community species composition are not generalizable across regions, and more representative studies are needed in understudied diverse biomes. This study serves as an important counterpoint to work done in the Neotropics by providing contrasting predictions for Afrotropical forests with substantially different ecological, evolutionary, and anthropogenic histories.
