Aboriginal and historical sites better protected following erosion control works
20 July 2017
A Western Local Land Services coordinated project that led to important works being carried out at the Angledool Aboriginal cemetery and historical site continues to reduce the impacts of erosion a year after the final inspection for the project was carried out.
After many years of widespread watersheeting and gully erosion, Western Local Land Services, in conjunction with a number of stakeholders including the Office of Environment and Heritage, conducted site visits in 2014 and 2015 and formulated a plan to address the erosion in the area.
The main goals were to:
- Reduce the volume of water flowing down the gullies. This was achieved through earthworks that now absorb as much water as possible high up in the catchment before entering the major gullies outside the fenced area.
- Reduce the speed of water flowing down the gullies. By spreading the water as much as constraints would allow, the erosive energy of the water was reduced.
While the final inspection for the project was carried out midway through last year, Western Local Land Services Aboriginal Communities Officer, Blackie Gordon has continued to monitor the site and is pleased with the positive impact the works have had.
“We were able to get a lot of expert advice about how to best carry out the erosion control works and everyone that was involved in the project is pleased with what has been achieved,” Mr Gordon said.
“By constructing things like absorption pits, de-silting dams to increase the volume of water they can hold and creating some shallow wetlands, the cemetery and historical sites won’t be nearly as affected by erosion in the years to come.
“We also widened five bywashes and a number of rock gabions were constructed at key points to reduce the speed of concentrated water.”
During the project, Western Local Land Services undertook appropriate care and consideration to ensure they did not disturb any Aboriginal sites.
While there are many known sites in the area, since it has not been comprehensively surveyed and there could be unknown sites of cultural value, it was decided earthworks would be kept to areas that had previously been worked on in 1994/95.
Landholders and community members that know of an Aboriginal or historical site that they would be interested in protecting, should contact their nearest Western Local Land Services Office.
Funding for this project was provided through Catchment Action NSW.
