An award-winning Kiwi photo is coming under the environmental microscope because its idyllic mauve carpet is made up of lupins.
The flowers are pretty but they are running over New Zealand's wildlife, pushing out native birds that rely on the increasingly scarce native flora lupins are replacing.
The picture, taken by Richard Bloom, won the International Garden Photographer of the Year competition. Writing in the Guardian, conservationist Robbie Blackhall-Miles said "there is no doubt that it is an incredible photograph".
The photo, entered in the wildflower landscapes category, was praised to the hilt by impressed judges, but Blackhall-Miles suggested Bloom was aware of the potential fallout, when the photographer said of the snap: "On the way to Lake Tekapo on the South Island of New Zealand in early summer the landscape, already amazing, was scattered with drifts of naturalised lupins." Naturalised - or non-native.
Blackhall-Miles wondered if the judges knew about the problems lupins were causing in New Zealand when they handed out the award.
