TL;DR: Understanding grass–tree interactions in savanna requires consideration of the long-term effects of life history–disturbance interactions on demography, rather than the fine-scale effects of resource competition on physiological performance.

TL;DR: In this paper, the authors measured fire intensity in the Kruger National Park, South Africa, by documenting fuel loads, fuel moisture contents, rates of fire spread and the heat yields of fuel in 956 experimental plot burns over 21 years.

TL;DR: Evidence is provided that savannas are demographically resilient to fire, but structurally responsive, and the density of woody individuals was unresponsive to fire.

TL;DR: In this article, the authors analyse changes in woody density in fire experiments at three sites in South African savannas where the disturbance regime (fire and herbivores) was kept constant for 30 and 50 years.

TL;DR: In this article, a disc pasture meter was successfully calibrated for estimating grass fuel loads in the main landscapes of the Kruger National Park, where the calibration comprised estimating the mean disc height of a 4 m2 quadrat and harvesting the grass as close to ground level as possible.
