“…The mean carbon sequestration of the floral species in the core area was higher than that of the buffer area. Typically, most PAs are perceived to sequester varied amounts of carbon with respect to the buffer and core zones respectively due to the unequal distribution of soil nutrients and other growth requirements (Boakye et al, 2017). However, from…”

“…Kettenring et al (2006) reports that light requirements for germination contribute to the formation of persistent seed banks in Carex species. Other factors accounting for the difference in diversity could be the uneven spatial distribution of soil nutrients and other growth requirements in the soil (Boakye et al, 2017).…”

“…Yet, the stocks of carbon, diversity, abundance, richness and spatial distribution of species within the sanctuary have been given limited attention. Again, limited effort has been made towards assessment of edge effects (Boakye et al, 2017). Thus, effects of edges on the sanctuary need to be assessed in order to make informed decisions on the conservation status of the protected forest ecosystem.…”

The study assessed the functional status of the University of Energy and Natural Resources' (UENR) bat sanctuary by examining its floral species diversity and carbon stocks. Twenty-nine sampling points (plots) were randomly generated by using the ArcGIS random sampling algorithm. Using a three-nest sampling plot of 100 m 2 , 25 m 2 , and 1 m 2 quadrat, the enumeration of trees (DBH > 10 cm), saplings (>2 cm DBH < 10 cm) and seedlings (girth < 2 cm) was undertaken, respectively. Additionally, the diversity of each floral species was computed using the Shannon Wiener diversity index whilst the carbon stocks were estimated using allometric equations. The total carbon stock per plot was derived from the summation of the aboveground carbon (AGC), belowground carbon (BGC) and deadwood carbon (DWC). In sum, 485 floral individuals belonging to 58 species and 25 families were enumerated with Bignoniaceae (16.4%), Apocynaceae (10.0%), Caesalpiniaceae (9.2%) and Rubiaceae (8.8%) being the most common families within the protected area (PA) based on their Importance Values (IV). The average carbon sequestered per hectare of the PA was 2789.3 tons. However, there was no significant difference (p > 0.05) between the 10 m buffer created and the core area with respect to floral species diversity and carbon stocks. The study had provided valuable information on the functional status of the bat sanctuary, which will help promote its conservation for sustained provision of ecosystem services.

The growth of trees in riparian forests in semi-arid savannas is resilient to the natural variations in temperature and precipitation due to the availability of riverine water. Climate change can nevertheless, intensify the evapotranspiration of tree species, altering biodiversity, plant productivity and ecosystem services. Understanding the growth response of riparian tree species to climate change is, therefore, critical for their management and conservation. Here, we used 23 cross-dated stem discs of Anogeissus leiocarpus (DC.) Guill. and Perr. and Afzelia africana Sm. randomly sampled from riparian forests in the humid and dry savanna regions of Ghana to assess their growth response to climate change. A generalized additive mixed model (GAMM) was used to integrate species-specific basal area increments to an array of explanatory variables that may affect growth, including tree size and seasonal temperature and precipitation between 1982 and 2013. We observed significant association between tree size, rainy and dry season temperatures and precipitation variables, and changes in tree growth. Despite the strong fluctuations in tree growth over time, the estimated growth rates of the species from the residuals of the GAMMs showed no significant change in growth. Our findings suggest that these riparian forests are highly resistant to weather extremes and therefore, might persist (up to a certain point) even if climate change continues to intensify.
