The study finds that the effect of this pollution basically stopped an important type of fast-growing coral, called Acropra, from growing in damaged areas, preventing the reef from repairing itself after major disturbances like storms or damage by boats dragging anchors.
“There was a very significant shift in the coral community composition that was associated with the colonization of Queensland,” marine biologist and co-author John Pandolfi told Live Science. “They just weren’t able to come back after the 1950s.”
Although human activities near the reef are currently managed by the Australian government, they don’t yet have any regulations on farming runoff, which the study’s authors recommend. “Any kind of measures that are going to improve the water quality should help those reefs to recover,” Pandolfi reportedly said.
