  1. DISTRIBUTION AND ABUNDANCE OF THE BENTHOS IN THE SEDIMENTS OF LAKE CUBHU: A FRESHWATER COASTAL LAKE IN ZULULAND SOUTH AFRICA

    DISTRIBUTION AND ABUNDANCE OF THE BENTHOS IN THE SEDIMENTS OF LAKE CUBHU: A FRESHWATER COASTAL LAKE IN ZULULAND SOUTH AFRICA

    Item type: Journal Article • Journal: Journal of the Limnological Society of Southern Africa • Authors: D.P. Cyrus --- Coastal Research Unit of Zululand, Department of Zoology, South Africa T.J. Martin --- Coastal Research Unit of Zululand, Department of Zoology, South Africa
    A preliminary investigation of the macrobenthic invertebrates of the sediments of Lake Cubhu, a freshwater coastal lake near Richards Bay was conducted on a quarterly basis during 1987. The most important factor which determined the abundance and distribution of each...

  2. The effect of harvesting operations, slash management and fertilisation on the growth of a <em>Eucalyptus</em> clonal hybrid on a sandy soil in Zululand, South Africa

    The effect of harvesting operations, slash management and fertilisation on the growth of a Eucalyptus clonal hybrid on a sandy soil in Zululand, South Africa

    Item type: Journal Article • Journal: The Southern African Forestry Journal • Authors: ColinW Smith Ben du Toit
    Harvesting operations during clearfelling and extraction of timber from commercial plantations result in many processes that may affect long-term site productivity such as soil compaction and residue manipulation. The objective of this work was to evaluate the effects of various...

  3. Alternative eucalypt species for Zululand: Seven year results of site: species interaction trials in the region

    Alternative eucalypt species for Zululand: Seven year results of site: species interaction trials in the region

    Item type: Journal Article • Journal: The Southern African Forestry Journal • Authors: R A W Gardner --- , South Africa
    The ICFR initiated a search for alternative eucalypt species for the Zululand Coastal Plain region during 1992 by establishing a series ofsite: species interaction trials in the area. Sixteen pure species (seedlings), one E. grandis intra-specific clone and five inter-specific...
