Wildfire is a major disturbance in Baikiaea plurijuga Harms woodland savannas. We tested the hypothesis that the timing and intensity of herbivory influence fuel loads. We used three stocking rates namely light (three cows and four goats ha)1), medium (six cows and eight goats ha)1) and heavy (e...

Human-induced fires are a major disturbance in Baikiaea plurijuga woodland savannas that are economically important for timber production. Most fires occur during the late dry season, when they may severely damage woody plants. Prescribed burning during the early dry season is a management strate...

A review of the occurrence of wild fires in Sengwa Wildlife Research Area (SWRA), Zimbabwe, is presented for the period 1965-1993. The effectiveness and desirability of early burning of peripheral areas introduced in 1979 are evaluated. More than 75% of wild fires occurred between July and Octobe...

Evaluation of the effectiveness of an early peripheral burning strategy in controlling wild fires in north-western Zimbabwe
During the decade a 'new rangeland science' has emerged. One of the tenets of this science is that pastoralists should not adhere to a single conservative stocking rate but rather, adopt an opportunistic strategy where numbers will fluctuate widely in response to good and bad seasons. It is furth...

A dynamic ecological model, calibrated with field data from the communal lands of southern Zimbabwe where Shangaaan and Ndebele people live, shows the ilala palm, Hyphaene petersiana, to be resilient to a wide range of harvesting regimes. The degree of use determines the plant population structur...
