Barbary lion breeding shows improvements

A recent paper on improving conservation decision making (Black, 2015) includes some of the data used in developing the Moroccan Royal Lion studbook (Black, Yamaguchi, Harland and Groombridge, 2010) as previously gathered by the author with Dr Nobuyuki Yamaguchi (University of Qatar) and Adrian Harland (Aspinall – Port Lympne Wild Animal Park).

Data on productivity (in this case, the number of cubs born) shows that since the initiative to revisit and re-catalogue the lions known to be direct descendents of the King of Morocco’s collection there has been a marked increase in the production of new cubs. The great news is that these are also form well-matched pairs with no further in-breeding.

However the analysis also shows that a greater level of breeding is still needed to bring the  natural regeneration of the population under control. Currently there are practical restrictions to achieving this since clearly there are limits to the capacity that zoos have for increasing lion group sizes and for controlling breeding behaviour.
