Assessing Translocation Success or Failure of the African Buffalo (Syncerus caffer) in Post‐War Mozambique Using Species Distribution Modelling

African Journal of Ecology, Volume 64, Issue 5, July 2026.
ABSTRACT Post‐war Mozambique provides a rare setting to evaluate ecological models of African buffalo (Syncerus caffer) translocation outcomes. Following severe declines caused by armed conflict, translocations were implemented to restore ecological functioning.
