“…Although resprouting has become recognized as a key functional trait in plant ecology over the past decade (Lawes and Clarke 2011), there is still limited information about the physiology and growth strategies of resprouting trees in savannas (Neke 2004;Pote et al 2006). Available information about the influence of disturbance and cutting frequency comes from ecosystems that are different when compared with savannas.…”

Key message Although exposure to multiple cutting cycles reduces stored reserves, shoot diameter and shoot length, it, however, increases shoot production per resprouting stump and foliar nitrogen. Abstract In disturbance-prone environments with fluctuating seasonal rainfall such as savannas, the repeated cutting of the same trees eventually results in a possible decline in tree abundance. The effects of subjecting Terminalia sericea trees to one, two and multiple (eight) cutting events over a period of 2 years on coppice response were investigated in a savanna woodland in South Africa. Resprout shoot diameter, shoot length and the total cumulative diameter were lower in trees exposed to a high number of cutting events compared to trees exposed to one cutting event. Increasing the number of cutting events significantly reduced stem total non-structural carbohydrate levels in trees indicating a depletion of stored reserves. Foliar carbon content remained largely the same, while leaf nitrogen and phosphorus concentrations significantly increased with each cutting event, relative to uncut trees. Results indicate that trees cut once had not replenished depleted carbohydrate reserves even after a period of 18 months during which no cutting took place. Sustainable utilization of this tree species must allow for at least more than 18 months of undisturbed growth between harvests to allow for the replenishing of reserves.

“…Regardless of the high representation of J. globiflora and B. speciformis and many other endemic woody plants at local or regional scale, these Miombo woody species are threatened by anthropogenic activities especially wood poaching as recorded in this study and this could be attributed to their hardwood type preferred for fuel wood, poles, construction and carpentry [5]. Our results are consistent with those of others like Pote et al [5] and Furukawa et al [30] who observed that these species besides being dominant in miombo woodlands are also preferred because of their basal circumference, as evidenced in this case by the stump size. Mukuvisi Woodland, being almost surrounded by urban residential areas is subjected to anthropogenic pressure where human livelihoods like energy needs are heavily dependent on wood derived from the study area.…”

“…This amid growing concerns that wood poaching is negatively impacting on woodlands dynamics in African savanna [2]. Woody vegetation is important as it provides products and services such as fuel, timber, fodder, especially in developing countries [3,4], habitats for avifauna, canopy environments for wildlife and nutrient rich pools within a harsh landscape [5][6][7]. Wood harvesting and strong selectivity for both woody species and size class are rarely factored into fuel wood harvesting models or impacts on woody vegetation structure and composition.…”

“…The expansion of agriculture land is generally considered to be the main cause of deforestation in tropical Africa (e.g. Boahene 1998;Adedire 2002;Zhang et al 2002;Pote et al 2006). Through this practice, substantial quantities of wood resources are collected for household energy source or either burn on field or left in the agricultural fields.…”

Fuelwood in Rwanda is assumed to come from forests and woodlands, thus contributing to large-scale deforestation. Available studies on fuelwood demand and supply support this assumption and indicate a continuously rising demand of fuelwood, notably from forest plantations. These assertions are insufficiently substantiated as existing forest stock may not be depleted by rapid increase in demand for food and energy resources resulting from population growth, but rather from the need for agricultural land. Evidence suggests that the demands for fuelwood, in addition to other sources of energy, is supplied from agroforestry systems which has not been quantified so far. This review analyses sources and use of fuelwood in Rwanda, indicating the importance of on-farms trees and woodlots in fuelwood supply. It is concluded that the effect of fuelwood consumption on land use is difficult to disentangle as many other factors including land clearing for agriculture, livestock farming, human settlements, illegal cutting of valuable timber species, the demand for charcoal in towns and past conflicts, contributed significantly to the high rate of deforestation in the country. If fuelwood demand is to be met on a sustainable basis, more fuelwood has to be produced on agricultural lands and in forest plantations through species site matching and proper management.
