dc.description.abstract The aim of this study was to determine to what extent research findings (relating to fire management) which were conducted at. Cathedral Peak, situated in the northern Drakensberg, could be used to determine fire management po1icy in the southern Drakensberg. Two major issues were tackled. Firstly the influence of topography (elevation, slope and aspect) and time since burn on the standing green and dead fuel load. Secondly, the influence of topography on the nature of curing of the sward. <br><br> The investigation into the influence of topography on fuel load showed elevation to be the main environmental factor governing the fuel load (both green and dead) at any given time. It was found that a negative relationship existed between elevation and fuel load. Models have been proposed for prediction of both green and dead fuel load as well as the relationship between total fuel 1oad and fuel-bed depth. The study further revealed no significant difference in yield between the 1984/85 and 1985/86 seasons. This would indicate that the models developed for prediction of fuel load (green and dead) could be extrapolated to faci1itate use outside the season used for their development. <br><br> The pattern of curing was found to be consistent over the entire elevational gradient studied. South facing slopes, however, displayed significant greening-up in the period June July. <br><br> The final recommendations to management are: (1) fuel loads determined at elevations of less than 2 000 m asl at Cathedral. Peak should not be employed for the determination of fire behaviour on the Highmoor Plateau; and (2) the burning of south facing slopes during June-July should be discontinued until the effect of this burning practice on the survival of temperate species has been determined. en
