  1. A vegetation-based hierarchical classification for seasonally pulsed floodplains in the Okavango Delta, Botswana

    A vegetation-based hierarchical classification for seasonally pulsed floodplains in the Okavango Delta, Botswana

    Item type: Journal Article • Journal: African Journal of Aquatic Science
    A classification scheme is presented for seasonal floodplains of the Boro-Xudum distributary of the Okavango Delta, Botswana. This distributary is subject to an annual flood-pulse, the inundated area varying from a mean low of 3 600 km2 to a mean...
  2. Influence of flood variation on seasonal floodplain vegetation communities in the Okavango Delta, Botswana

    Influence of flood variation on seasonal floodplain vegetation communities in the Okavango Delta, Botswana

    Item type: Journal Article • Journal: African Journal of Aquatic Science
    This study investigated the influence of flooding variation on floodplain vegetation in the Nxaraga Lagoon seasonal floodplains by sampling community composition and soil nutrient content in 1997, when flood levels were unusually low, and again in 2010 when flood levels...
  3. A baseline classification of riparian woodland plant communities in the Okavango Delta, Botswana

    A baseline classification of riparian woodland plant communities in the Okavango Delta, Botswana

    Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science
    In the Okavango Delta information on the riparian woodland vegetation community composition and distribution is generally lacking. Past studies in the Delta were mainly focused on the quantitative classification of seasonal floodplain herbaceous vegetation communities. The aim of this study...
  4. Mapping inundation extent, frequency and duration in the Okavango Delta from 2001 to 2012

    Mapping inundation extent, frequency and duration in the Okavango Delta from 2001 to 2012

    Item type: Journal Article • Journal: African Journal of Aquatic Science
    The frequency and duration of inundation in river systems are important for a variety of applications, such as water resource management, floodplain mapping and habitat restoration. The Okavango Delta, the fifth largest Ramsar site in the world, has experienced a...
  5. Role of <em>Brycinus lateralis</em> (Teleostei: Alestidae) in dispersal and germination of <em>Nymphaea nouchali</em> (Angiospermae: Nymphaeaceae) seeds on a seasonal floodplain of the Okavango Delta, Botswana

    Role of <em>Brycinus lateralis</em> (Teleostei: Alestidae) in dispersal and germination of <em>Nymphaea nouchali</em> (Angiospermae: Nymphaeaceae) seeds on a seasonal floodplain of the Okavango Delta, Botswana

    Item type: Journal Article • Journal: African Journal of Aquatic Science
    Seed passage through the gut of vertebrates can be important for seed dispersal, but might influence seed viability. The ability of seeds to germinate after ingestion by seed-eating fish is important for the population dynamics of some plant species, and...
  6. Floristic and Structural Composition of Hanglip Forest in the Soutpansberg, Northern Transvaal

    Item type: Journal Article • Journal: South African Forestry Journal
    The closed, evergreen forest of 363 ha was sampled by means of 62 circular plots of 0,04 ha, distributed in a grid pattern. TWINSPAN classification separated the forest into regrowth forest with two forest types, and mature forest with four...
  7. 2. Veld reinforcement for increased meat production

    2. Veld reinforcement for increased meat production

    A programme of radical veld improvement applied on a farm in a cool, high rainfall area of East Griqualand is described. The veld was burnt in spring and fertilized with 300 kg/ha superphosphate and 45 to 60 kg/ha N. It...
