H.  aAn approach th monitoring of changes in the composition and utilization of woodland and Savana vegetation.h[electronic resource]  c1976  aAbstract: The paper descriptionbes a scheme for recording vegetation composition and utilization in the tree, shrub and herbaceous layers. It is based on a set of permanently located transects of variable size, distributed so as to cover the variation within previously determined habitat types. The assessment procedure is designed to minimize errors associated with subjective estimates and personal bias, and includes measurements wherever these are not unduly laborious or time consuming. Recording is carried out using six printed forms, four of which are designed for automatic data processing. The actual categories and definitions of use or damage on the forms may be changed to suit the needs of the particular monitoring programme. The computer programmes have been tested on two sets of data, using all the options (e.g. mature trees only vs. all trees) and are hopefully bug-free. It is usually preferable to assess the herbaceous and woody layers at different seasons. The last of the assessments (BROWSE) is not strictly a monitoring procedure, and is normally carried out as an independent exercise.  aHerbaceous plants  aPastures  aVegetation  aWoodlands  aPastagem Nativa  aVegetação  tSouth African Journal Wildlife Researchgv. 6, n. 1, p. 1-32, 1976.
