. Savanna‐grassland ecosystems are highly interactive due to effects among interconnected trophic elements. This can cause disturbance at one level in the trophic web to be propagated through that web to have effects far removed from the initial locus of disturbance. The reconstructed effects of rinderpest upon African savannas, acting directly upon susceptible grazers and browsers but in directly upon many other ecosystem components, are used as a case history illustrating the propagation of disturbance in savanna ecosystems.
