“…The tree species, which had no seedlings and saplings exhibited discontinuous population structures. Earlier studies also reported that a lack of stand-level regeneration occurred commonly in Ethiopian forests (Girma and Mosandl 2012;Fisaha, Hundera, and Dalle 2013) and across tropical forests (Anitha et al 2010). In Kahtasa forest, 15 tree species were represented only by few individuals in the adult stages.…”

Species composition, structure, and regeneration status of trees were assessed in five dry Afromontane forests. In each of the forests, trees having ≥5 cm diameter at breast height were identified and measured in 80 quadrats (20 × 20 m 2). We compared tree species composition and similarities, stem densities, frequencies, basal area and importance value index of trees. Harvesting index was calculated to 13.3% in the least disturbed and 22.5% in highly disturbed forests. A total of 1,655 individuals representing 38 species and 28 families were recorded. The tree densities varied from 364.1 to 664.1stem ha −1 with an average basal area of 20.7 m 2 ha −1. The analysis showed significant differences in basal areas of tree species between the least and highly disturbed forests. Seedling densities ranged from 2000 to 8162.5 stem ha −1 and sapling densities ranged from 512.5 to 2562.5 stem ha −1. The anthropogenic disturbances revealed high degradation of population structure and regeneration statutes of the trees in the studied forest ecosystem. In conclusion, the study provided empirical results on the dominance, population structure, importance value and regeneration status of tree species, which would be instrumental for the development of successful rehabilitation strategies for the studied forests.

“…As an important branch of digital earth, digital forestry is essential for sustainable forest management (Kirby and Potvin, 2007) and forest ecosystem investigation (Guariguata, 2000), involving the specific topics such as on forest population declines (Davies et al, 2000), climate-growth relationships (Gebrekirstos et al, 2008) and forest biodiversity (Anitha et al, 2010). Tree species information serves as the fundamental data.…”

“…These communities are usually dominated by deciduous tree species of lower stature and smaller leaf size than found in the deciduous broadleaf savannahs, and numerous species have spines (locally dominant genera include Boswellia, Capparis, Acacia, Dichrostachys, Ziziphus and Catunaregum) [51,53,54,56,70]. Two environmental drivers seem most important for the structure of fine-leafed and spiny savannahs.…”

The savannahs of Asia remain locally unrecognized as distinctive ecosystems, and continue to be viewed as degraded forests or seasonally dry tropical forests. These colonial-era legacies are problematic, because they fail to recognize the unique diversity of Asian savannahs and the critical roles of fire and herbivory in maintaining ecosystem health and diversity. In this review, we show that: the palaeo-historical evidence suggests that the savannahs of Asia have existed for at least 1 million years, long before widespread landscape modification by humans; savannah regions across Asia have levels of C 4 grass endemism and diversity that are consistent with area-based expectations for non-Asian savannahs; there are at least three distinct Asian savannah communities, namely deciduous broadleaf savannahs, deciduous fine-leafed and spiny savannahs and evergreen pine savannahs, with distinct functional ecologies consistent with fire-and herbivory-driven community assembly. Via an analysis of savannah climate domains on other continents, we map the potential extent of savannahs across Asia. We find that the climates of African savannahs provide the closest analogues for those of Asian deciduous savannahs, but that Asian pine savannahs occur in climates different to any of the savannahs in the southern continents. Finally, we review major threats to the persistence of savannahs in Asia, including the mismanagement of fire and herbivory, alien woody encroachment, afforestation policies and future climate uncertainty associated with the changing Asian monsoon. Research agendas that target these issues are urgently needed to manage and conserve these ecosystems.This article is part of the themed issue 'Tropical grassy biomes: linking ecology, human use and conservation'.
