Stump size was significantly and positively related with coppice density for some of the species, but not with shoot vigour for the majority of the species. The mean coppice density ranged from five to eight shoots per stump while the mean height of coppice shoots ranged from 46 cm to 118 cm with marked inter-species variations. A total of 369 stumps of 11 species were recorded with mean coppice stumps ranged from six to 84. An inventory was conducted in areas that were harvested for charcoal production by the local people. We tested the hypotheses that (a) species, stump diameter, stump height and time since cutting have significant effects on the number of sprouts per cut stump (coppice density) and mean sprout height (shoot vigour) and (b) higher coppice density reduces shoot vigour due to competition among coppice shoots in a given stump. Thus, the aim of this study was to examine whether regeneration by coppice is a viable option for sustainably managing miombo woodlands for biomass fuel production. However, there are growing concerns about the sustainability of harvesting for biomass fuel (mainly charcoal). The miombo woodland is one of the most extensive woodlands in Africa, supporting biomass fuel-based livelihoods of millions of rural people. The outstanding regrowth capacity of these three species indicates that the forest remnant under study may eventually consist of populations with a predominance of species capable of coppicing. Lewis, Aspidosperma pyrifolium Mart., and Cnidoscolus quercifolius Pohl., resulting in a greater number of individuals of a few species. and Sapium glandulatum (Vell.) Pax and predominance of Cenostigma bracteosum (Tul.) E. There was a decrease in the number of species 2 years after cutting, mainly due to the loss of Croton rhamnifolius H. The survival and mortality of the stumps were quantified, as well as changes in the horizontal structure and floristic diversity. In addition, all individual shrub-tree species (CAB ≥ 4 cm) not included in the post-cut situation were identified, measured (CAB and height total) and tagged as persisting (6 cm ≤ CAB) or growing (6 < CAB ≤ 4 cm) in 2015. Height and circumference at the base (CAB) of the stumps and shoots were obtained for two situations: pre-cut (grouping by live and dead stumps) and (ii) post-cut (shoots on only live stumps). Permanent plots were installed in a Caatinga in the municipality of Floresta-PE, Brazil, in 2013, and measured 2 years after clearcutting. The objective of this work was to characterize the survival, structure, and diversity of Caatinga submitted to coppicing under sustainable forest management comparing pre- and post-harvest conditions. Therefore, the recovery of the timber stock for the next cycle will depend on the regrowth and survival capacity of the exploited species, as well as on the future structure of the forest. Rational exploitation of Caatinga wood resources consists of sustainable forest management under coppice systems. Coppicing facilitates the long-term persistence of this dry forest, and the rapid growth of coppice shoots contributed to the resilience of most species after cutting. The average height and diameter of the leading shoots after 10 y were 4.5 m and 3.8 cm, respectively, and the average percentage diameter recovered by the shoots varied between 36% and 95% among the species. Coppicing was vigorous for most tree species, but the average number of shoots per stump decreased significantly over the 9 y period, from 25 to 8 shoots per stump. The number of coppice shoots and the height and dbh of the leading shoots were measured on the tree stumps 14 mo and 10 y after cutting. The fate of coppice shoots was tracked on a total of 481 stumps, representing 51 species over 10 y. This study reports on the growth and dynamics of coppice shoots following experimental cutting in a tropical dry forest in Jamaica. Coppicing is an important regeneration mechanism in tropical dry forest after disturbance, but little is known about the long-term dynamics and the rate of recovery of the coppice shoots following clearance.
