Snapshot: Repairing the Aranda Snow Gums site – a fulfilling activity
The Aranda Snow Gums Natural Heritage Site is a rare urban remnant of our formerly widespread snow gum communities. The site slopes from the ridge south of Aranda down to the Glenloch Interchange and was badly degraded after pasture enhancement and stock grazing, with deep gullies and sheet erosion. It is slowly recovering, but natural revegetation is inhibited by kangaroos and drought. Along with government agencies, the Friends of Aranda Bushland (FoAB) energetically tackled the accelerated restoration of the natural biodiversity values.
The erosion areas were treated with matting sown with native grass seed to slow water flows, but germination was quite poor in 2007’s tough drought. Rangers placed large logs across an eroding walking track to divert water into an adjoining, well-vegetated drainage line, and community volunteers dug in smaller logs around the site to slow water and provide habitat for local grassland and woodland species.
Tubestock from seeds collected on site, or nearby, was planted along banks and drainage lines with wattle along the deep gully, sedge and tussock grass in damp areas, snow grass on slopes and lilies under the snow gums. Again, the harsh drought slowed the success rate but, with more favourable conditions expected in 2008, further plantings will be undertaken.
FoAB volunteers are not just filling in time; they are filling in the results of erosion - one more example of an ACT conservation group working to create a better environment for us all.
