These decisions need to be Africa (Figure 1).

Concurrently, the intact natural Miombo woodlands are under increasing pressure to provide all the resources mentioned above – not only to the rural population, but also to the ever- increasing urban population via trade and businesses. This may result in degradation of the woodlands and deforestation, which in turn reduces the resources that may be extracted. We estimate that between 250,000 and 300,000 ha/year of Miombo are degraded and/or lost (Miombo Network Meeting, July 2016). Figure 1.

  • The Miombo Woodlands of Central, Eastern and Southern Africa
    90 The Miombo Woodlands of Central, Eastern and Southern Africa Philomena Tuite and John J. Gardiner Dept. of Crop Science, Horticulture and Forestry, University College Dublin, Belfield. Dublin 4. Summary Aspects of the environment and ecology of Miombo woodlands are described. Attention is given to the widespread nature of their distrihution area and the role played by Miombo at local and national levels. A matrix of woodland-use is presented. This offers some insight into changing resource-usc patterns in Miombo, and highlights the conflicts which may ensue with the adoption of certain woodland management strategies. Iutroduction In Africa, tropical dry forests and woodlands constitute between 70 - 80% of all forested land (Murphy & Lugo 1986). South of the Equator, (50 to 25 0 S) Miombo woodlands are the main dry for· est type in the continent, occupying an estimated area of 7 million square kilometres (Griffith 1961). Thus, Miombo represents one of the most widespread, yet compact forest types in the world. Almost 50% of the land area of both Tanzania and Zambia, and large tracts of Mozambique, Malawi, Zimbabwe, Zaire and Angola support Miombo (Fig. 1). This aereal distribution corresponds roughly to the Zambezian Floral Domain of White (1965), recognised for its floristic richness and the widespread occurrence of the tree genera Brachystegia, lulbernardia and Isoberlinia. Despite the widespread nature of this woodland type, its long history of exploitation and the increasing human·related pressure and needs within the countries mentioned, Miombo resource-use re­ mains largely undocumented.

  • Using Natural Fertilizers in Miombo Woodlands by Emmanuel Chidumayo
    ISSUES 'IN AFRICAN BIODIVERSITY THE BIODIVERSITY SUPPORT PROGRAM IYwmber 2, May 1999 Using Natural Fertilizers in Miombo Woodlands By Emmanuel Chidumayo Introduction Miombo woodlands grow on the ancient central African plateau and its escarpments. They form a swathe across the continent from Angola to Mozambique, and extend from lhnzania and southern Congo in the north, to Zimbabwe in the south. Scientists distin- guish miombo from other savanna woodland and forest formations by the presence of legume trees belonging to the genera Brachustegia, Julbernardia, and Isoberlinia. The climate in the miombo zone is subhumid, characterized by a short seasonal rainfall rang- ing from 650 mm to 1,400 mm, occurring from November to March, and a long dry sea- son (April to October/November). Miombo is divided with the wetter type (with > 1,000 mm of rainfall) occurring in the north, and drier type (with < 1,000 mm) (White 1983) occurring in the south of the miombo zone. Miombo occurs on geologically old and acidic (pH 4-6) soils with low fertility. A charac- teristic association between miombo tree species and ectomycorrhizal fungi significantly increases mineral uptake from the soil. There is higher species diversity in miombo woodlands and associated wetlands or dambos than, for example, acacia woodlands. Miombo is of outstanding international importance for the conservation of plants and birds, many of whichare endemic to the region. It provides seasonal habitat for two large, spectacular antelope in Africa, the roan and sable. Miombo trees are typically highly resilient to the annual fires that sweep across the region, and resprout rapidly after anthropogenic disturbance; however, woodland regeneration can be stalled or prevented if trees are uprooted and the connection with ectomycorrhiza is disturbed.

Box FM730, Famona, Bulawayo, Zimbabwe PREFACE The Miombo Ecoregion Vision Report was commissioned in 2001 by the Southern Africa Regional Programme Office of the World Wide Fund for Nature (WWF SARPO). It represented the culmination of an ecoregion reconnaissance process led by Bruce Byers (see Byers 2001a, 2001b), followed by an ecoregion-scale mapping process of taxa and areas of interest or importance for various ecological and bio-physical parameters. The report was then used as a basis for more detailed discussions during a series of national workshops held across the region in the early part of 2002. The main purpose of the reconnaissance and visioning process was to initially outline the bio-physical extent and properties of the so-called Miombo Ecoregion (in practice, a collection of smaller previously described ecoregions), to identify the main areas of potential conservation interest and to identify appropriate activities and areas for conservation action. The outline and some features of the Miombo Ecoregion (later termed the Miombo– Mopane Ecoregion by Conservation International, or the Miombo–Mopane Woodlands and Grasslands) are often mentioned (e.g. Burgess et al. 2004). However, apart from two booklets (WWF SARPO 2001, 2003), few details or justifications are publically available, although a modified outline can be found in Frost, Timberlake & Chidumayo (2002). Over the years numerous requests have been made to use and refer to the original document and maps, which had only very restricted distribution.

  • Towards Community-Based Forest Management of Miombo Woodlands in Mozambique
    Towards community-based forest management of miombo woodlands in Mozambique Salomão, A1. and Matose, F2 ABSTRACT This case study analyses the devolution of forest management in Mozambique. The analyses are augmented by reviews of five CBNRM projects. The locus of power has historically lay with the centre, with local communities not being part of the governance system. Although the legal regime for CBNRM can be seen as progressive, a major outstanding problem relates to its implementation. It remains vague on pertinent aspects of community involvement, including the extent of community rights, powers and benefits in relation to those of other stakeholders. Time is also needed to change the attitude of state and other bureaucrats; those who were implementing top-down management now have to devolve power; the previous mindset remains. Communities are often sceptical of the state, so some of the implementation problems also come from their side, with an unwillingness to fully engage. At the same time, while forests form an important facet of the Mozambican economy it is clear that mechanisms put in place for communities to economically benefit from the commercialization of forest resources occurring in their areas are not adequately and effectively delivering on the envisioned benefits. In particular, the management requirements placed on communities to engage in business ventures are too stringent and thus limit involvement in such ventures. 1 Introduction................................................................................................................

  • Land Use Impacts on Miombo Woodland Species in Wenimbi Resettlement Area of Macheke, Zimbabwe
    Land Use Impacts on Miombo Woodland Species in Wenimbi Resettlement Area of Macheke, Zimbabwe. Katsvanga C.A.T., Mukwewa O., Mupangwa. J. F. and Buzuzi. G. Abstract The miombo woodlands are used in a diversity of ways that influence biodiversity and ecosystem stability most of which threaten woodland and agro-ecosystem sustainability. The study assessed the influence of three farming activities, namely tobacco, maize and horticulture production on Brachystegia spiciformis and Julbernadia globiflora tree species, which are dominant and are used in most household, construction and energy purposes. The fate of the timber harvested from the woodlands is important as it gives a clue on the most destructive farming activities and the size of trees required. Indicators to determine levels of deforestation, and capacity to regenerate were tree and stump populations per ha. For tree size preference, root collar diameter, stump and tree heights, and the ability of the remaining stumps to coppice were assessed. Residual tree density was lowest (P < 0.001) on the tobacco sites compared to the other two sites that also differed significantly. Stump population was highest in woodlands where maize is actively grown in comparison to horticultural and tobacco sites. However stump survival and coppicing capacity were significantly higher (P=0.000) in woodlands of maize and horticulture active growing farms. Overall, there is selective and preferential utilization of woody biomass by size depending on the fate of the biomass though this does not reflect itself by species. It is concluded that the agricultural activities influence the cover of the two tree species and this could have detrimental effects on the miombo ecosystem and on the sustainability and viability of the farming activities especially tobacco production that has impacted mostly on bigger diameter trees whilst horticulture production is affecting the smaller diameter trees leaving the older trees.

Selective harvesting decreases the likelihood of conspecific replacement and increases the risk of collapse of the natural successional pathway. This method is unsustainable in that it does not support recruitment of timber species, as these species are light demanders. This has the ability to result in total collapse of the population that are being harvested if the situation persists for a long time as there would be no recruitment with time into the higher size class when individuals die. To ensure sustainable harvesting, policymakers across the region must take into account a number of factors, including: • Development and implementation of woodland management plans based on growth rates of timber species. This should provide for regulation of initial harvesting and subsequent cutting cycles. • Silvicultural prescriptions for major vegetation types and species based on their functional traits and disturbance factors. • Integrated silvicultural systems that accommodate different commercial applications (e.g charcoal, timber, honey).
