The Queensland government has spent $7m buying the 560 sq km
Springvale Station, situated south of Cooktown, the ABC reported on Wednesday.
Cattle stations cause erosion and long gullies that pour
sediment into rivers that drain into the water around the Great Barrier Reef.
The Queensland environment minister, Steven Miles, said
badly degraded grazing land on this one property was responsible for 40% of the
sediment that flows from gully erosion into the Normanby River.
“Runoff from land carries sediment from the Normanby basin
to the outer reef where it blocks light, smothers marine organisms and reduces
coral and seagrass growth,” he said.
The Normanby River flows into the ocean near Lizard Island,
where the Guardian revealed shocking images of coral bleaching and mortality
this year.
