  1. Conservation Developments in South African Forestry

    Item type: Journal Article • Journal: South African Forestry Journal
    The historical development of environmental conservational activities within the South African Forestry Industry is followed, and the changing emphasis from the conservation of the remaining indigenous forests (pre-1900) to water conservation, to natural assets and unplanted areas is highlighted. The...
  2. The global impact of alien trout species—a review; with reference to their impact in South Africa

    The global impact of alien trout species—a review; with reference to their impact in South Africa

    Item type: Journal Article • Journal: African Journal of Aquatic Science
    Rainbow and brown trout have been introduced into at least 82 countries, where they have significantly impacted indigenous fish, aquatic invertebrates and amphibians. In many studies the second, and sometimes the first, most serious identified threat to indigenous aquatic fauna...
  3. Determining the minimum effective dose of rotenone for eradication of alien smallmouth bass <em>Micropterus dolomieu</em> from a South African river

    Determining the minimum effective dose of rotenone for eradication of alien smallmouth bass <em>Micropterus dolomieu</em> from a South African river

    Item type: Journal Article • Journal: African Journal of Aquatic Science
    In February 2012 the Rondegat River, in the Cape Floristic Region, was the first river in South Africa where the piscicide rotenone was used to remove an alien invasive fish, smallmouth bass Micropterus dolomieu. In preparation for this treatment, the...
  4. Gastropod diversity, distribution and abundance in habitats with and without anthropogenic disturbances in Lake Victoria, Kenya

    Gastropod diversity, distribution and abundance in habitats with and without anthropogenic disturbances in Lake Victoria, Kenya

    Item type: Journal Article • Journal: African Journal of Aquatic Science
    We investigated freshwater gastropod diversity, abundance and distribution in habitats with and without anthropogenic disturbance in two localities, Ndere in the Winam Gulf and Mbita Point, Lake Victoria, Kenya, from May 2002 to January 2004. A total of 133 984...
  5. A preliminary survey and analysis of the spatial distribution of aquatic invertebrates in the Okavango Delta, Botswana

    A preliminary survey and analysis of the spatial distribution of aquatic invertebrates in the Okavango Delta, Botswana

    Item type: Journal Article • Journal: African Journal of Aquatic Science
    The spatial distribution of aquatic macroinvertebrates in the Okavango River Delta, Botswana, was investigated during the low-water period in February 2003. This complements an earlier study undertaken during high-water in June 2000. Seventy-five samples were taken in a range of...
  6. Caddisfly (Trichoptera) larvae of the Opa River basin, south-western Nigeria

    Caddisfly (Trichoptera) larvae of the Opa River basin, south-western Nigeria

    Item type: Journal Article • Journal: African Journal of Aquatic Science
    Caddisflies in the streams of the Opa River catchment basin in Ile-Ife, south-western Nigeria, were surveyed, documenting nine genera in six families. Hydropsychidae is the most speciose family, with three genera, and has the highest number of individuals in the...
  7. Small mammal diversity and density on the Bokkeveld escarpment, South Africa – implications for conservation and livestock predation

    Small mammal diversity and density on the Bokkeveld escarpment, South Africa – implications for conservation and livestock predation

    Item type: Journal Article • Journal: African Zoology
    A preliminary investigation of the diversity and density of small mammals in four structurally distinct habitat types in an actively-utilized farming landscape was carried out. We sought to understand how diversity and density are influenced by landscape structure, habitat structure...
  8. The influence of fire on rodent abundance at the N’washitshumbe enclosure site, Kruger National Park, South Africa

    The influence of fire on rodent abundance at the N’washitshumbe enclosure site, Kruger National Park, South Africa

    Item type: Journal Article • Journal: African Zoology
    The relative population numbers of rodents were studied in nine habitats in and outside the N’washitshumbe enclosure site, Kruger National Park, before and after burning the firebreaks that surround the enclosure. Trap success was exceptionally high, and the field work...
  9. Grazing depletes forb species diversity in the mesic grasslands of KwaZulu-Natal, South Africa

    Grazing depletes forb species diversity in the mesic grasslands of KwaZulu-Natal, South Africa

    Item type: Journal Article • Journal: African Journal of Range & Forage Science
    Forbs constitute over 80% of the species richness of mesic grassland but their response to grazing is largely unknown. The influence of grazing on the forb composition, richness and diversity of two species-rich grasslands in the coastal hinterland and midlands...
