  1. A South African softwood sawtimber supply chain case study

    A South African softwood sawtimber supply chain case study

    Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science
    Supply chain management principles were analysed by investigating the effects of smaller-scale and incremental interventions in a forest-to-mill value chain on financial returns and forest resource use in an Eastern Cape case study area. Three previous studies provided input by...
  2. Production Capacity of Softwood Sawmills in the Republic of South Africa, Swaziland and Transkei

    Item type: Journal Article • Journal: South African Forestry Journal
    The technical and practical capacities of softwood sawmills and boxmills in the Republics of South Africa, Transkei and Ciskei and the Kingdom of Swaziland were estimated as at 30 June 1987. These estimates show that sawmills in Southern Africa are...
  3. A Technique for Producing Soil Water Retention Curves

    Item type: Journal Article • Journal: South African Forestry Journal
    Water retention curves compiled for specific soil types are an essential management and research tool in evaluating plant stress. The method of producing water retention curves by means of the 1500 kPa pressure extractor is described.
  4. Storage of <em>Pinus radiata</em> Foliage Prior To Determination of Water Potential

    Item type: Journal Article • Journal: South African Forestry Journal
    A procedure to sample and store foliage of Pinus radiata seedlings prior to determination of the water potential is described. The water potential of P. radiata fascicles sampled at pre-dawn can be maintained for seven hours by storing the foliage...
  5. Water Retention in Cultivated Forest Soils of the Southern Cape Province

    Item type: Journal Article • Journal: South African Forestry Journal
    In South Africa, commercial tree planting is restricted because of limited water resources in the soil. Therfore, it is important to recognise relevant soil characteristics and soil amelioration techniques to optimise water supply for best tree growth. The Gompertz function...
  6. Short‐term burning treatments and ecological interactions in the herb layer of false thornveld of the eastern province

    Short‐term burning treatments and ecological interactions in the herb layer of false thornveld of the eastern province

    The effects of five years of controlled burning on total floristic composition and on some important species were investigated.
  7. Names of Southern African grasses: Name changes and additional species reported since 1955

    Names of Southern African grasses: Name changes and additional species reported since 1955

    In the twenty‐five years since Chippindall's ‘Guide to the Identification of Grasses’ in Meredith The Grasses and Pastures of South Africa (1955), which covered about 910 species and subspecific taxa, there have been 227 name changes and 1791 additional species...
