  1. Silviculture and Genetics of <em>Pinus kesiya</em> for Planting Degraded Pasture Land

    Silviculture and Genetics of <em>Pinus kesiya</em> for Planting Degraded Pasture Land

    Item type: Journal Article • Journal: The Southern African Forestry Journal
    The conifer species, Pinus kesiya Royle ex Gordon, is an important part of the ecology within the indigenous range of South-east Asia as well as in sustainably managed plantations in a number of countries. Planting with the species in Colombia...
  2. Potential for genetic improvement of yield of exotic softwood tree species in Rwandan plantation forestry1

    Potential for genetic improvement of yield of exotic softwood tree species in Rwandan plantation forestry1

    Item type: Journal Article • Journal: The Southern African Forestry Journal
    Exotic softwoodtree species playamajorrole in Rwandan plantationforestry. Theyareusedto produce sawn timber used for various purposes. Pinus patula is the major commercial species. Growth and yield of this species were compared in terms of seed source variation based on two trials,...
  3. Growth models based on radial increment observations for eight pine species in Angola

    Growth models based on radial increment observations for eight pine species in Angola

    Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science
    Growth models for the Central Highlands of Angola were developed in this study for Pinus pseudostrobus Lindl., P. kesiya Royle ex Gordon, P. devoniana Lindl., P. chiapensis (Martinez) Andresen, P. elliottii Engelm., P. greggii Engelm. ex Parl., P. montezumae Lamb...
  4. Development and validation of stem volume models for <em>Pinus kesiya</em> in Benguet province, Philippines

    Development and validation of stem volume models for <em>Pinus kesiya</em> in Benguet province, Philippines

    Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science
    Stem volume equations (overbark) were developed, using established volume equation forms, and validated using a subset of the data collected for Pinus kesiya in Benguet province, Philippines. A total of 481 trees from Pinus kesiya stands in Benguet were measured...
  5. Effect of weeding and fertilisation on bark thickness and stem form of seven pine species on a low-elevation site at Usutu, Swaziland

    Effect of weeding and fertilisation on bark thickness and stem form of seven pine species on a low-elevation site at Usutu, Swaziland

    Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science
    On a low-elevation site at Usutu alternative species to Pinus elliottii, the species recommended in the past for such sites, were planted to evaluate growth differences. At rotation age, destructive stem profile analyses were conducted on some of the trees...
  6. Productivity and cost analysis of semi-mechanised and mechanised systems on the Viphya forest plantations in Malawi

    Productivity and cost analysis of semi-mechanised and mechanised systems on the Viphya forest plantations in Malawi

    Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science
    At least 200 000 m3 of timber is harvested annually using semi-mechanised harvesting systems on the Viphya forest plantations in Malawi. Although these systems have long been used on the Viphya, no investigation on their productivity has so far been...
  7. The implication of using a fixed form factor in areas under different rainfall and soil conditions for <em>Pinus kesiya</em> in Zambia

    The implication of using a fixed form factor in areas under different rainfall and soil conditions for <em>Pinus kesiya</em> in Zambia

    Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science
    The study was undertaken to evaluate form factors for Pinus kesiya growing in the three Zambia Forest and Forestry Industries Corporation (ZAFFICO) plantations – the Ndola, Ichimpe and Chati groups – under different rainfall (900–1 500 mm) and soil conditions (pH...
  8. Determining Transpiration from <em>Pinus patula</em> Shoots—A Comparative Evaluation of the Cut-Shoot Method and Two Null-Balance Diffusion Porometers

    Item type: Journal Article • Journal: South African Forestry Journal
    The cut-shoot method and two types of small-chambered null-balance diffusion porometer were evaluated for suitability in studies of stomatal conductance and transpiration in Pinus patula. In the course of the cut-shoot evaluation, excised shoots were found to transpire at a...
  9. Litterfall and Nutrient Release in Mature <em>Pinus radiata</em> in the South-western Cape

    Item type: Journal Article • Journal: South African Forestry Journal
    Fast-growing plantations of conifers have replaced areas of mediterranean shrubland in the south-western Cape. This study arises from the need to quantify the impacts of major changes in primary productivity, litterfall, and nutrient cycling in terms of the site utilisation...
  10. Evidence of Induced Nutrient Deficiency in Pine Plantings on Previously Cropped Lands

    Item type: Journal Article • Journal: South African Forestry Journal
    Widespread establishment failures of Pinus species have recently occurred on agricultural land acquired for commercial forestry in South Africa. These include about 10 000 ha of previously tilled soils in the north-eastern Cape belonging to Mondi Forests. A lettuce (Lactuca...
