The inclusion of biogenic very-short lived bromine (VSL^Br) in a chemistry-climate model produces an expansion of the ozone hole area of ~ 5 million km², which is equivalent in magnitude to the recently estimated Antarctic ozone healing due to the reduction of anthropogenic CFCs and halons. The maximum Antarctic ozone hole depletion increases by up to 14 % when natural VSL^Br are considered, but does not introduce a significant delay of the modelled ozone return date to 1980 October levels.
