  1. The application of camera trapping to assess Rallidae species richness within palustrine wetland habitat in South Africa

    The application of camera trapping to assess Rallidae species richness within palustrine wetland habitat in South Africa

    Item type: Journal Article • Journal: Ostrich: Journal of African Ornithology
    Wetlands are vital habitats for a variety of organisms and ecosystem services, but the health of these valuable habitats is declining worldwide. The Rallidae species that rely on these habitats are typically elusive, cryptic and difficult to monitor accurately, especially...
  2. Die invloed van winterbrand en sny op die seisoenshooiproduksie van <em>eragrostis curvula</em> (schrad) nees

    Die invloed van winterbrand en sny op die seisoenshooiproduksie van <em>eragrostis curvula</em> (schrad) nees

    Deur middel van ‘n 33 faktoriale proef is die invloed van drie metodes van ontblaring (jaarliks sny, jaarliks brand, en sny en brand jaarliks afgewissel), gedurende drie verskillende tye (Julie, Augustus en September) op bemeste (O N + P; 53...
  3. 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.
  4. Continuous grazing on <em>cenchrus ciliaris</em>

    Continuous grazing on <em>cenchrus ciliaris</em>

    Breeding cattle grazed Cenchrus ciliaris continuously for four years. Excellent calving percentages (mean 95,25%) and good weaning masses (mean 245 kg) were obtained, the A.D.G.’s being 0,963 kg for heifers and 1,075 kg for bulls. The system was planned to...
  5. Influence of macchia eradication techniques on botanical composition of grasses in the döhne sourveld of the amatole mountains

    Influence of macchia eradication techniques on botanical composition of grasses in the döhne sourveld of the amatole mountains

    Grass communities identified through association‐analysis were used for determining the effects of several methods for eradicating and controlling macchia. Follow‐up burns at three frequencies applied over a ten‐year period to control macchia were found to have masked most differences in...
  6. Implikasies van subhabitat‐diversiteit en die rol van bestuur op die voorkoms van ‘n aantal grasspesies van die suuragtige‐gemengde bosveld<sup>1</sup>

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Die subhabitatvoorkeure van sewe grasspesies en die nie‐grasagtige kruide, tipies van die Suuragtige‐Gemengde Bosveld, is in agt kampe, wat verskillende langtermyn‐beweidingsbehandelings ontvang het, ondersoek. Twee subhabitatte is geidenti‐fiseer, nl. onder borne en tussen bome. Verskille in die subhabitatvoorkeure van die...
  7. A simple, inexpensive method for estimating linear tree dimensions

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    A simple, inexpensive method for estimating linear tree dimensions is described and tested. The method is based on a visual overlap of two images, namely, the tree to be estimated and a group of length scales incorporated on a colour...
  8. Quantitative description of woody plant communities: Part I. An approach

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Various descriptive units for woody plant communities are proposed. These are the Evapotranspiration Tree Equivalent (ETTE), Browse Tree Equivalent (BTE) and Canopied Subhabitat Index (CSI), which describe the status of a woody community in terms of potential moisture use, value...
  9. Quantitative description of woody plant communities: Part II. Computerized calculation procedures

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Calculation procedures for various quantitative descriptive unit‐values are described. These procedures are divided into primary and secondary calculations. The former is then divided into the calculation of spatial tree volume and preliminary calculations regarding the complete quantitative description. The latter...
  10. Assosiasie van <em>Cymbopogon plurinodis</em> met klei‐inhoud van grond in die Suuragtige‐Gemengde Bosveld<sup>1</sup>

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Association of Cymbopogon plurinodis with the day content of soil in the Sourish Mixed Bushveld. In a camp, typical of the Sourish Mixed Bushveld, a marked decrease in the abundance of Cymbopogon plurinodis along a soil gradient from high to...
