The utility of panoramic photographs for studying the extent and pattern of vegetation change, in particular of bush encroachment, was investigated by revisiting thirteen sites in the Weenen and Muden areas of KwaZulu-Natal that had been photographed in 1955. The ubiquitous feature of all sites was the marked increase in woody cover, from a mean of 21% woody cover for all topographic units (plains, hill slopes, river bank and river terrace) in 1955, to 59% woody cover in 1998. Although sample sizes were small, the increase in woody cover was greater on hill slopes (45% mean increase in woody cover) than on the plains (26%), and on north-facing slopes (56%) rather than on south-facing slopes (32%). The increase in woody plant cover was accompanied by a change in composition from open or mixed woodland, to one dominated byAcaciaspecies, in particular byA. tortilisat lower altitudes and byA. karrooat higher altitudes. In some cases, scrubAcaciaindividuals were already evident in the photographs in 1955, and had grown into mature trees by 1998. Recruitment of bothAcaciaand broad-leafed species was also observed in 1998 and there was a tendency for bush clumps to develop. Broad-leafed species have dominated on moist south-facing slopes and at higher altitudes. Increases of the arborescent leaf succulents.Aloe spectabilisandOpuntia ficus-indicaand of the dwarf, stem succulent shrub,Euphorbia pseudocactus, have occurred. Fire is no longer a component of this landscape which, together with the open condition in 1955, resulting from overgrazing. may account for the vegetation changes that have taken place. Panoramic photographs proved an effective tool for monitoring vegetation change because changes in composition and structure were revealed, and because each photograph samples a large area of ground at an adequate resolution.
