Effects of Afforestation and Clearfelling on birds and small Mammals at Grootvadersbosch, South Africa
Item type: Journal Article • Journal: South African Forestry Journal • Authors: A.J. Armstrong --- Department of Nature Conservation, Republic of South Africa H.J. van Hensbergen --- Department of Nature Conservation, Republic of South AfricaResults from a short-term study of birds and small mammals in pine plantations, regenerating clear-felled sites and indigenous forest and fynbos habitats at Grootvadersbosch, southern Cape, indicate that the pine faunal assemblages are pauperised in relation to those of the... -
Commercial Forestry on Signal Hill and Lion's Head, Cape Town
Item type: Journal Article • Journal: South African Forestry Journal • Authors: Chrisna Joubert --- Department of Nature Conservation and Oceanography, Cape TownThe history of afforestation with alien tree species on Signal Hill and Lion's Head, which form part of the Table Mountain Nature Reserve, Cape Town, was reconstructed. The natural vegetation comprises mostly West Coast Renosterveld which is considered the most... -
A Protocol for Wildlife Conservation Planning in an Afforestable Montane Grassland Region
Item type: Journal Article • Journal: The Southern African Forestry Journal • Authors: A.J. Armstrong --- Department of Nature Conservation, South Africa H.J. van Hensbergen --- Department of Nature Conservation, South AfricaThe grassland biome is the biome most transformed by human activity in South Africa. At least thirteen percent of the biome is suitable for pine afforestation. There is a need for conservation evaluations before large-scale commercial afforestation to determine which... -
Treatment Effects on Annual and Dry Period Streamflow at Cathedral Peak
Item type: Journal Article • Journal: South African Forestry Journal • Authors: J.M. Bosch --- Department of Forestry,Total annual streamflow and dry season flows of treated catchments at Cathedral Peak, Natal, were compared and related to those of index catchments. -
Litter Fall and Decomposition in Stands of Mature Pinus radiata
Item type: Journal Article • Journal: South African Forestry Journal • Authors: D.B. Versfeld --- Department of Water Affairs, Forestry and Environmental Conservation,Rates of litter fall in mature stands of Pinus radiata D. Don have been monitored at the Jonkershoek Forestry Research Station since 1976. Decomposition trials were laid out in June 1977. Litter fall has been collected on six sites in... -
Climatic and Altitudinal Criteria for Commercial Afforestation with Special Reference to Natal
Item type: Journal Article • Journal: South African Forestry Journal • Authors: A. P.G. Schönau --- Wattle Research Institute and Department of Agricultural Engineering, South Africa R.E. Schulze --- Wattle Research Institute and Department of Agricultural Engineering, South AfricaCriteria of altitude and climate such as mean annual precipitation, mean annual. January and July temperatures, mean daily maximum and minimum temperatures for January and July respectively and duration of soil moisture deficit are given for five main commercial tree... -
A new approach to modelling streamflow reductions resulting from commercial afforestation in South Africa
Item type: Journal Article • Journal: The Southern African Forestry Journal • Authors: M.B. Gush --- Environmentek CSIR, D.F. Scott --- Department of Earth and Environmental Sciences, Canada G.P.W. Jewitt --- School of Bio-Resources Engineering and Environmental Hydrology, R.E. Schulze --- School of Bio-Resources Engineering and Environmental Hydrology, L.A. Hallowes --- , A.H.M. Görgens --- Dept. of Civil Engineering,The Department of Water Mfairs and Forestry has, for some time, needed a comprehensive tool to incorporate the impacts of commercial afforestation on water resources into water use authorisation and allocation processes. Simulation modelling on a national scale, using the... -
Establishment of a Nothofagus alessandrii plantation using different levels of shade and weed control methods in Talca province, central Chile
Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science • Authors: R Santelices --- Department of Forestry Science and Dryland Technology Centre, Faculty of Agrarian and Forestry Sciences, Chile F Drake --- Department of Forest Management and Environment, Faculty of Forestry Sciences, Chile RM Navarro-Cerrillo --- Department of Forest Engineering, Faculty of Agronomy and Forestry, SpainThere is a lack of information regarding the establishment of Nothofagus alessandrii plantations, including any impacts that shading and weed control may have on early survival and growth. A trial was therefore initiated where four shade levels (0% and Rachel®... -
Deforestation since independence: a quantitative assessment of four decades of land-cover change in Malawi
Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science • Authors: Rachel A Bone --- Centre for Environmental Sciences, Faculty of Engineering and the Environment, UK Kate E Parks --- Centre for Environmental Sciences, Faculty of Engineering and the Environment, UK Malcolm D Hudson --- Centre for Environmental Sciences, Faculty of Engineering and the Environment, UK Mathews Tsirinzeni --- LEAD Southern and Eastern Africa, Chancellor College, Malawi Simon Willcock --- Centre for Biological Sciences, Faculty of Natural and Environmental Sciences, UKLand cover has changed rapidly across the tropics over the past century; however, detailed historical information describing the extent and possible drivers of such change is widely lacking. Here, we constructed a history of land-cover change at the district level... -
Topo-edaphic environment and forest plantation disturbance explain patterns of grassland species richness, composition and structure in an agro-ecological landscape, Maputaland, South Africa
Item type: Journal Article • Journal: African Journal of Range & Forage Science • Authors: AP Starke --- , South Africa TG O’Connor --- , South Africa CS Everson --- , South AfricaGrasslands of the Maputaland coastal plain are biologically diverse and provide a variety of ecosystems services. Yet grasslands in this region are vulnerable to continuing development by plantation forestry that provides economic benefits to local communities. In order to provide... -
Soil carbon stock assessment using depth and spatial models on afforested arable lands
Item type: Journal Article • Journal: South African Journal of Plant and Soil • Authors: Trevan Flynn --- , Czech Republic Liesl Wiese --- , South Africa Andrei Rozanov --- , South AfricaThe change from grasslands and natural shrubs to afforested arable land has a major impact on soil organic carbon (SOC) stocks. Grasslands are known to be SOC sinks as seen in the Chernozems of North America, Eurasia and South Africa... -
The impact of Eucalyptus plantations on herpetofaunal diversity, Maputo National Park, Mozambique
Item type: Journal Article • Journal: African Journal of Herpetology • Authors: PR Jordaan --- Tshwane University of Technology, South Africa A Wilken --- University of Pretoria, South Africa X Combrink --- Tshwane University of Technology, South AfricaExotic afforestation has proven detrimental to biodiversity in general, however only a few studies documenting the impact of timber plantations on herpetofaunal diversity have been published within a southern African context. To determine if variations in herpetofaunal species assemblages could...
