Emissions higher in mossy wetlands with brumbies: study

Brumby-trampled mossy wetlands in the Australian Alps are releasing more carbon dioxide into the atmosphere than those undisturbed by feral horses, a study shows.

Researchers from RMIT University measured carbon dioxide emissions in 12 alpine and subalpine peatlands in NSW's Kosciuszko National Park.
