  • S8617 - Minimum raised on basis of records suggesting >500 in far west, >500 in Chad basin, >500 in Central Africa forest block and >500 elsewhere.
  • T6609 - General increase in the Senegal Delta, where it was only rarely recorded in the past. Although uncertain/fluctuating in the long-term, IWC data shows strong increase since 2003.
