| Abstract |
Environmental heterogeneity across savanna landscapes may play key roles in determining plant (MacFayden et al. 2016), large mammal and bird diversity (Harrington et al. 1999; Fuhlendorf et al. 2006; Krook et al. 2007). This heterogeneity also determines the strength of density-dependent feedbacks on large herbivore population growth and their viability (Hobbs et al. 2008; Hopcraft et al. 2010).
The Savuti-Mababe-Linyanti ecosystem, northern Botswana is a relatively pristine region of the northern conservation area containing extensive savanna woodlands sandwiched between the permanent water sources of the Okavango Delta and Linyanti Swamps, where large areas of woodland may occur > 20 km from permanent water sources, beyond the maximum movement distance of the more mobile bull elephants during the dry season. |
