“…They together compose 34% of the total IVI. These species are typical of the dry Miombo systems of this eco-region [6,43,44]. The results also show that the study site is dominated by 20 species and they represent 53% of all the trees.…”

“…The knowledge of species diversity is useful for establishing the influence of biotic disturbance and the state of succession and stability in the environment [36,37]. This species diversity index increases with the number of species in the community [6,38]. The Pielou's evenness (Eq) measures the diversity degree of a stand compared with the possible maximum and is computed as Eq.…”

“…Ecologically, the density and the frequency of a species measure the distribution of a species within the population, while the basal area measures the area occupied by the stems of trees [6].…”

“…Factors, such as geomorphic evolution of the landscape [16], edaphic factors, principally soil moisture and nutrients [2] and past and present land use, and other anthropogenic disturbances [6,17], have all been implicated. According to Chidumayo [5], anthropogenic activities play a big role in the dynamics of Miombo woodlands.…”

“…Miombo woodland is distinguished from other African savanna. In Miombo woodland, woodland and forest are formed by the dominance of tree species in the family Fabaceae, subfamily Caesalpinioideae, particularly in the genera Brachystegia, Julbernardia and Isoberlinia [3,4], while these genera are seldom found outside Miombo [5,6]. Miombo is regarded as a vegetation type that has been used by humans since the upper Pleistocene and maintained by man through a long history of cutting, cultivation and frequent dry season fires over the last 55,000 year [7].…”

Forest assessments are essential to understand the tree population structure and diversity status of forests and to provide information for biodiversity recovery planning. Unfortunately, the majority of Miombo woodlands in Mozambique lack of inventory data, and consequently are often insufficient for management. This study aimed to assess the species richness, diversity and structure of Miombo woodlands using a range of sampling sizes in Mocuba district, Mozambique. Plant inventory was carried out in 128 systematically selected sample plots in 71.6 ha, which was divided into eight treatments, i.e., T1: 0.1 ha; T2: 0.25 ha; T3: 0.375 ha; T4: 0.5 ha; T5: 0.625 ha; T6: 0.75 ha; T7: 0.875 ha; T8: 1.0 ha, with 16 repetitions. All stems ≥ 10 cm diameter at breast height, and species name to evaluate the floristic composition, richness of tree species, diversity and diameter distribution were recorded. A total of 36,535 individuals were recorded, belonging 124 species, 83 genera and representing 31 botanical families. The most important species was the Brachystegia spiciformis Benth. and the richest botanical family was Fabaceae. The forest showed an average of 517 ± 85 trees/ha, and high species diversity and evenness. Analysis of covariance shows that the intercepts and slope of exponential function for diameter distribution are not significantly different for the eight treatments. Compared with the entire composite forest, inventory means were accurately estimated and size class distributions were well represented for plots ≤ 0.25 ha, for selecting an efficient sampling design suited to forest characteristics and the inventory's purpose.
