Four catchments,varying in size from 3 16 ha and treated with a combination of different anti鄄erosion meas鄄
ures viz. afforestation,fencing and gully control structures were monitored for runoff and soil loss(Table 1). The
catchment 玉 was fenced,planted with native vegetation with gully control structures installed in the highest鄄order
gullies; catchment 域 was fenced and planted with native vegetation; and catchment 芋 was fenced only. The
catchment 郁 was kept untreated and was designated as control(C). The fencing was carried out with barbed gal鄄
vanized iron wire fixed thrice all around the catchment using cemented(reinforced concrete cement) fixtures with
the aim of preventing wild animals from grazing and deforestation by humans. The native vegetation mainly com鄄
prised of Acacia catechu trees and Eulaliopsis binata grass. The engineering structures for plugging the gullies were
gabions and lose rock dams(made from the locally鄄available stones) installed as check dams in series at upper,
middle and lower segments of the main(highest鄄order)gullies(Fig郾 1 and Fig郾 2).
