Footes Hill station has not been as heavily cleared as other properties in the district, with good stands of Ironbark and Corymbia woodland across the property. However, under previous management, some erosion gully areas developed above the Haughton River. There has also been a change in the vegetation with native shrubs and grasses being replaced by exotic plants such as Chinee apple and Rubber Vine.
The gullies on Footes Hill Station were identified in 2018 as having good potential for saving sediment from entering the Great Barrier Reef. After initial investigations, it was estimated that these gullies were losing over 2,000 tonnes of sediment annually, with this sediment flowing straight into the Haughton River and out into the Great Barrier Reef.
In 2019, on-ground remediation of the Western, Central and Alluvial gully complexes were completed. These works included the construction of three overland flow diversion bunds, head cut and gully reshaping, the construction of rock chutes, and six hectares of revegetation with pasture grasses.
In addition to the on-ground remediation works, a new fence was established to allow the landholders to better manage grazing of the remediated sites. In this newly established paddock, 30 ha of exotic weeds such as Chinee apple and rubber vine were also removed.
After the works were complete the sites were regularly monitored and surveyed to track the success of the remediation works. A control gully with no treatment was also monitored to confirm that gully restoration works did make an improvement.
In 2021, the control gully was remediated using the same method as employed for the Western, Central and Alluvial gully complexes, along with improved grazing management and weed control.
These remediation works have saved 1,810 tonnes of sediment annually at the original site, and 561 tonnes at the control site, for a total of 2,371 tonnes annually stopped from reaching the Great Barrier Reef.
