Dibharra Seed Orchard and Revegetation

Recovery at Dibharra

We have been involved with a revegetation project for the 20 Million Trees program on Aboriginal Community Land near Moonta, South Australia.  The 42 Ha revegetation site is located on the York Peninsula, where annual rainfall is 350 mm; it comprised recently grazed paddocks, dense with pasture weeds.

Following some initial weed control, the site was seeded with a mix of coloniser species, which provided rapid, robust competition for the weedy seedbank. The seed mix consisted of native grasses (Austrostipa spp., Rytidosperma spp., Enneapogon spp., Enteropogon spp. and Chloris spp.) and chenopods (Atriplex spp., Enchylaena spp., Maireana spp. and Rhagodia spp.).

Our services included:

  • Design and establishment of a seed orchard at Dibharra
  • Weed control and direct seeding activities
  • Supply of 80 kg of native grasses, chenopods, and shrubs
  • Annual monitoring and reporting surveys

A Successional Approach

Our unique approach to revegetation involves a ‘ground up’ methodology, which floods a site with seeds of native colonising species. The use of colonising species provides rapid site stabilisation and initiates the process of recovery to build ecosystem function. These species add organic carbon to the soil, attract invertebrates, deposit seed, compete with weeds and provide cover. Colonising species in the arid zone can reproduce within 6–8 weeks of rainfall, bolstering the seedbank. These attributes provide a great catalyst for building ecosystems in the arid zone.
