Fertilising Commercial Forest Species in Southern Africa: Research Progress and Problems (Part 1)
Item type: Journal Article • Journal: South African Forestry Journal • Authors: M.A. Herbert --- , South Africa A. P.G. Schönau --- , South AfricaSince the inception of forest fertiliser research in Southern Africa in 1926, eight eucalypt, six pine and four acacia species have been tested, encompassing a wide range of sites in summer, winter and uniform rainfall areas. Marked deficiencies of P,... -
Interspecific hybrids in Zimbabwe: status review and future challenges
Item type: Journal Article • Journal: The Southern African Forestry Journal • Authors: D.P. Gwaze --- , USASeveral F1 eucalypt and pine interspecific hybrids have been tested in Zimbabwe. The first hybrids tests were of pine species, and these were established in 1973. The results from these early tests were not spectacular and interest in hybrids was... -
Understanding and adding value to Eucalyptus fibre
Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science • Authors: CRE Clarke B Palmer D GoundenEucalyptus wood has become one of the most important hardwood resources for pulp mills worldwide. Furthermore, bleached Eucalyptus pulp is used extensively both in paper-making globally where it is included in such diverse products as tissue, packaging, as well as... -
A tool for identifying potential Eucalyptus nitens seed orchard sites based on climate and topography
Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science • Authors: Ilaria Germishuizen --- Institute for Commercial Forestry Research, South Africa Robin AW Gardner --- Institute for Commercial Forestry Research, South AfricaShy seed production in orchards of Eucalyptus nitens is a major barrier to the deployment of genetic gain in South African plantations. A machine learning method was used to identify optimal sites for the establishment of E. nitens seed orchards... -
Modelling growth behaviour in monoculture in subtropical eastern Australia of two eucalypt species that differ in shade tolerance
Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science • Authors: Philip W West --- Forest Research Centre, School of Environment, Science and Engineering, Australia Kevin Glencross --- Forest Research Centre, School of Environment, Science and Engineering, Australia J Doland Nichols --- Forest Research Centre, School of Environment, Science and Engineering, AustraliaGrowth behaviour of the relatively shade-intolerant species Eucalyptus dunnii and the rather more shade-tolerant Corymbia citriodora was considered during several growth periods over 8–14 years of age in experimental plantation monoculture in subtropical New South Wales. Larger trees dominated growth... -
Harvesting and extraction impacts on Eucalyptus grandis × E. urophylla coppicing potential and rotation-end volume in Zululand, South Africa
Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science • Authors: Kylle Schwegman --- Nelson Mandela Metropolitan University, South Africa Keith M Little --- Nelson Mandela Metropolitan University, South Africa Andrew McEwan --- Nelson Mandela Metropolitan University, South Africa Simon A Ackerman --- Institute for Commercial Forestry Research, South AfricaFrom the early 2000s there has been a general shift in South Africa in harvesting and extraction systems from the use of semi- to fully-mechanised systems. Any increase in mechanisation, as is occurring in Zululand, will need to take into... -
Estimation of genetic parameters for growth in a population of Eucalyptus grandis × Eucalyptus nitens hybrids in KwaZulu-Natal and Mpumalanga
Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science • Authors: W Brink --- Sappi Shaw Research Centre, South Africa G van den Berg --- Sappi Shaw Research Centre, South Africa A Nel --- Sappi Shaw Research Centre, South Africa B du Toit --- University of Stellenbosch, South AfricaHybridising Eucalyptus grandis with Eucalyptus nitens produces progeny intended to combine the favourable traits of both parents. E. grandis exhibits good growth, stem form, wood properties and rooting ability for vegetative propagation. E. nitens displays superior cold tolerance, including superior...
