Effect of cutting height and frequency on Leucaena leucocephala forage and wood production
Item type: Journal Article • Journal: African Journal of Range & Forage Science • Authors: J.P. Muir --- , MozambiqueLeucaena leucocephala is a fast‐growing tree that can provide both high quality forage and firewood. The objective of this trial was to determine the optimum height and frequency of cutting for both wood and forage production. Cutting heights at 0.3... -
Nutrient cycling by Acacia erioloba (syn. Acacia giraffae) in smallholder agroforestry practices of a semi-arid environment in the North West Province, South Africa
Item type: Journal Article • Journal: The Southern African Forestry Journal • Authors: R.N. Murovhi S.A. MaterecheraAcacia erioloba is an ecologically important indigenous leguminous tree in semi-arid areas of Southern Africa because of the many benefits it offers to local communities. However, little quantitative plant and soil data exist to explain its ability to enhance soil... -
A Survey of Tree Planting Practices in the Smallholder Farming Sector of Zimbabwe
Item type: Journal Article • Journal: The Southern African Forestry Journal • Authors: EnosM. Shumba --- Forest Research Centre, Zimbabwe Abisai Mushaka --- Forest Research Centre, Zimbabwe Joseph Muchichwa --- Forest Research Centre, ZimbabweGroup meetings and individual farm visits were used to establish current tree planting practices in the smallholder farming sector of Zimbabwe. The number of tree species planted in each of the eight districts studied ranged from nine to 27 with... -
Silvopastoral system based on Ficus thonningii: an adaptation to climate change in northern Ethiopia
Item type: Journal Article • Journal: African Journal of Range & Forage Science • Authors: Mulubrhan Balehegn --- Animal Rangeland and Wildlife Sciences, Ethiopia Lars O Eik --- Department of International Environment and Development Studies, Ås, Norway Yayneshet Tesfay --- International Livestock Research Institute (ILRI), EthiopiaThis study in northern Ethiopia investigated local people's perception of climate change and the role of indigenous silvopastoralism in adaptation to that change. Two hundred and forty respondents participated in a questionnaire survey and group discussions. Local communities perceive climate... -
Determining fPAR and leaf area index of several land cover classes in the Pot River and Tsitsa River catchments of the Eastern Cape, South Africa
Item type: Journal Article • Journal: African Journal of Range & Forage Science • Authors: Anthony R Palmer --- Centre for African Conservation Ecology, South Africa Andiswa Finca --- Agricultural Research Council–Animal Production Institute, South Africa Sukhmani K Mantel --- Institute for Water Research, South Africa Onalenna Gwate --- Institute for Water Research, South Africa Zahn Münch --- Department of Geography and Environmental Studies, South Africa Lesley A Gibson --- Department of Construction and Surveying, UKDetermining the quantum (both annual maxima and minima) and the temporal variation in the leaf area index (LAI), and the fraction of photosynthetically active radiation (fPAR), are three fundamental biophysical characteristics of the plant canopy that should parameterise ecophysiological models... -
Survival and long-term growth of eucalypts on semi-arid sites in a Mediterranean climate, South Africa
Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science • Authors: Ben du Toit --- Department of Forest and Wood Science, South Africa Gideon F Malherbe --- Department of Forest and Wood Science, South Africa Anton Kunneke --- Department of Forest and Wood Science, South Africa Thomas Seifert --- Department of Forest and Wood Science, South Africa C Brand Wessels --- Department of Forest and Wood Science, South AfricaFour experiments were established on the semi-arid west coast plain of South Africa during the 1990s. The trails tested the survival and growth of several eucalypt species and hybrids, some of which were established in a climate that is drier... -
The development of reforestation options for dryland farmland in south-western Australia: a review
Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science • Authors: Richard J Harper --- School of Veterinary and Life Sciences, Australia Stanley J Sochacki --- School of Veterinary and Life Sciences, Australia John F McGrath --- School of Veterinary and Life Sciences, AustraliaCurrent forest industries in south-western Australia are based on regrowth natural eucalypt forests and Pinus and Eucalyptus spp. plantations, and restricted to areas with >600 mm y−1 annual rainfall. Dryland farming systems have been developed across 20 million ha in... -
Evaluation of agroforestry systems for maize (Zea mays) productivity in South Africa
Item type: Journal Article • Journal: South African Journal of Plant and Soil • Authors: Misheck Musokwa --- Agricultural, Earth and Environmental Sciences, South Africa Paramu Mafongoya --- Agricultural, Earth and Environmental Sciences, South Africa Simon Lorentz --- Agricultural, Earth and Environmental Sciences, South AfricaMaize (Zea mays L.) is the staple food crop grown by most smallholder farmers in South Africa. Decline in soil fertility and expensive chemical fertilisers affect maize production by these farmers. Smallholder farmers cannot afford chemical fertilisers because these are... -
Evaluation of soil physico-chemical properties as affected by canopies of scattered agroforestry trees on croplands
Item type: Journal Article • Journal: South African Journal of Plant and Soil • Authors: Shimbahri Mesfin --- , Ethiopia Hailay Haileselassie --- , EthiopiaAgroforestry tree species play an important role in improving soil fertility. Though studies have confirmed that different species show different potentials to improve soil fertility, it is difficult to compare them as the studies were conducted in different areas. The... -
Secondary vegetation provides a reservoir of non-timber forest products and agroforestry service options for forestry plantation systems, Maputaland, South Africa
Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science • Authors: AP Starke --- University of Pretoria, South Africa CJ Geldenhuys --- University of Pretoria, South Africa TG O’Connor --- University of the Witwatersrand, South Africa CS Everson --- University of KwaZulu-Natal, South AfricaTree species providing non-timber forest products (NTFPs) have the potential to enhance the socio-economic value of forestry plantation systems and mitigate biodiversity loss associated with production landscapes in Southern Africa. This can be accomplished by integrating NTFP agroforestry systems with... -
Silvicultural management strategies for climate change mitigation with the focus on plantation forests
Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science • Authors: Ben du Toit --- Stellenbosch University, South AfricaThis technical note explores several practical actions whereby short-rotation plantation forests in warm climates can be managed for increased resilience in the face of climate change. It includes landscape level issues such as ecosystem resilience, limiting the invasive tendencies of...
