Okavango Fire article in Landscape Ecology Journal
A paper titled "Interactions between fire and flooding in a southern African floodplain system (Okavango Delta, Botswana)" was recently published by HOORC associated researchers Heinl, Neuenschwander, Sliva and Vanderpost in the international journal Landscape Ecology.
Using analysis of 98 satellite images covering 15 years, the paper shows that there are higher fire frequencies on floodplains than on drylands because of higher biomass production and fuel loads. Fire occurrence on drylands shows a correlation with annual rainfall events, while fire frequency on floodplains is determined by flood frequency. The highest potential to burn was found for floodplains that get flooded about every second year. Landscape Ecology, Volume 21, 5, 699 - 709. [abstract]
