  1. Variable community responses to herbivory in fire-altered landscapes of northern Patagonia, Argentina

    Variable community responses to herbivory in fire-altered landscapes of northern Patagonia, Argentina

    Item type: Journal Article • Journal: African Journal of Range & Forage Science
    Landscapes in northern Patagonia have undergone dramatic changes in fire regimes over the last century. Superimposed on this changing vegetation mosaic are impacts from introduced herbivores. In this paper we identify synergistic interactions developing into positive fire-herbivory feedbacks that maximise...
  2. Applied disease screening and selection program for resistance to vascular wilt in Hawaiian <em>Acacia koa</em>

    Applied disease screening and selection program for resistance to vascular wilt in Hawaiian <em>Acacia koa</em>

    Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science
    Acacia koa is a valuable tree species economically, ecologically and culturally in Hawai'i. A vascular wilt disease of A. koa resulting from infection by the fungal pathogen Fusarium oxysporum f. sp. koae (FOXY) causes high rates of mortality in field...
  3. The Application of Inorganic Fertilisers to Conditioned <em>Pinus radiata</em> Prior to Lifting as a Means of Improving Root Growth Capacity

    Item type: Journal Article • Journal: South African Forestry Journal
    A modified root growth capacity technique was used to evaluate the effect of the application of different types and quantities of fertilisers on the root growth capacity (RGC) of conditioned Pinus radiata seedlings. The experiment indicates that 0,05 g N...
  4. Growth, Yield and Timber Density of Short Rotation Coppice Stands of <em>Eucalyptus grandis</em>

    Item type: Journal Article • Journal: South African Forestry Journal
    The effects of timing initial coppice reductions, number of reductions and final number of shoots per stool on growth and yield of Eucalyptus grandis are described. The basic data were obtained from three experiments situated in different climatic zones of...
  5. Impact of Wood Quality Assessments on Future Fibre Resources in the Pulp and Paper-making Industry

    Item type: Journal Article • Journal: South African Forestry Journal
    Recent evidence from research in Europe has indicated that individual trees can be sampled for their pulping properties by the removal of small quantities (5–50 g) of wood at about breast height (1,3 m above ground). Work began at Sappi's...
  6. Micropropagation <em>of Eucalyptus radiata ssp. radiata</em> Using Explants from Mature and Coppice Material

    Item type: Journal Article • Journal: South African Forestry Journal
    Nodes from young field-grown coppice regrowth and branches of a mature tree of Eucalyptus radiata ssp. radiata were cultured on a MS medium containing BA and NAA. BA at 0,5 mg/ℓ and NAA at 0,01-0,1 mg/ℓ were most effective in...
  7. Regeneration Procedures of <em>Pinus radiata</em> in the Southern Cape Province

    Item type: Journal Article • Journal: South African Forestry Journal
    Part 4 of the series of papers concerning the regeneration of Pinus radiata deals with characteristics of the planting stock. Such studies are motivated by the necessity of evaluating different planting stock alternatives for a variety of operational environments. This...
  8. Regeneration Procedures of <em>Pinus radiata</em> in the Southern Cape Province

    Item type: Journal Article • Journal: South African Forestry Journal
    The present paper is a continuation of the series dealing with the regeneration of Pinus radiata in the southern Cape Province. The study deals with post planting mortality and growth in response to the experimental treatments and planting site environment...
  9. Chemical Evaluation of Leaf Fibre Residues from Tropical Tree Legumes—a Wealth in Social Perspective

    Item type: Journal Article • Journal: South African Forestry Journal
    Leaf fibre residues obtained as a by-product during bulk extraction of leaf protein meal from three tropical forest trees viz. Albizzia procera Benth., Dalbergia sisso Roxb. and Delonix regia Raf. were analysed for their chemical and mineral composition. The fibres...
  10. The Effect of Site Preparation and Tending on the Growth of <em>Pinus radiata</em> in the Southern Cape: Five Year Results

    Item type: Journal Article • Journal: South African Forestry Journal
    This paper details the latest results of site preparation and tending experiments in Pinus radiata on regenerated sites, on both Kruisfontein Plantation in the Southern Cape District of the Western Cape Forest Region and Blueliliesbush Plantation in the Tsitsikamma Forest...
