Revegetation Portfolio

Alliance Seeds offers a revegetation service where we can tailor a revegetation solution to any problem.  Past projects we have been involved in include the rehabilitation of mining sites, roadsides, saline sites, golf courses, residential developments and sites affected by erosion.

We are able to contract grow many Australian native species of trees, shrubs, grasses, herbs and groundcovers and can also arrange seed collections from specific provenances.

International Power Hazelwood

Alliance Seeds has an ongoing contract with International Power Hazelwood to rehabilitate the overburden batters of the Hazelwood power station. 

Firstly, a cover crop of Ryecorn, Sheep’s Fescue and Hard Fescue was sown directly into the soil to help stabilise the area and to minimise erosion.  Numerous trials have since been carried out into the type of species that will grow in the clay, which lacks sufficient topsoil.  The most successful species, and therefore the most predominant species planted, is Danthonia setaceae. Species of Poa, Stipa and Themeda have all been planted in small colonies throughout the area with limited success. 

Alliance Seeds are responsible for the production of the plants in viro-cells grown from locally collected seed.  These viro-cells are then hand-planted directly into the overburden dumps, a method that has proven to be far more successful then direct seeding.

Capital Golf Course
The main aim of the project was to create a natural links look while keeping maintenance to a minimum.  This was achieved by planting Isolepis nodosa, Poa labillarderi, Lomandra longifolia and Dianella tasmanica as well as Allocasaurina verticillata to a density of 6 plants per square meter.  All grass species established rapidly eliminating competition from weed species and in doing so has reduced maintenance.

Huntingdale Golf Course
The aim of the project at Huntingdale was to use native species to improve the aesthetics of the course and keep maintenance to a minimum.

On approaches and mounds around the course Isolepis nodosa, Poa Kingsdake, Poa Eskdale, Lomandra Tanika and Lomandra longifolia were planted.  Lomandra Tanika, Dianella tasmanica and the attractive Grass Trigger Plant, Stylidium graminifolium were used in the garden beds. 

All plantings were carried out to a density of 6 plants per square metre to help eliminate competition from weed species.

Webb Dock
Plants for the revegetation project at Webb Dock were selected for their local significance and saline tolerance.  All indigenous species were grown and planted at 6 plants to the metre to reduce the impact of weeds.  A couple of years later, the vegetation is self-sustaining and free of weed species.

The following species were used in this project; Sclerostegia arbuscula, Sacococornia quinqueflora, Samolus repens, Tetragonia implexicoma, Triglochin striatum, Disphyma crassifolium, Atriplex cincerea, Correa alba, Rhagodia parabolica, Danthonia, Poa poiformis, Isolepis nodosa, Carpobrotus rossii, Mulenbaekia

Melbourne Docklands
This project involved reinstating indigenous flora after the realignment of the mouth of the Moonee Ponds Creek.  Floral surveys of the area found that all indigenous plant species were of local significance due to the extremely limited area of remnant vegetation in the City of Melbourne. 

The following species were planted to represent the salt-marsh and reed-bed plant communities of the area; Sclerostegia arbuscula, Sacococornia quinqueflora, Samolus repens, Tetragonia implexicoma, Triglochin striatum, Disphyma crassifolium, Atriplex cincerea, Correa alba, Rhagodia parabolica, Danthonia, Poa labilardieri, Isolepis nodosa, Carpobrotus rossii, Myoporum insulre, Acacia melanoxylon, Melaleuca ericifolia, Acacia paradoxa and Banksia integrifolia.

Eureka Centre - Ballarat
For the landscape around the new Eureka Centre in Ballarat, the Ballarat City Council wanted plants with a low water and maintenance requirement and that also had aesthetic value.  Both Poa Kingsdale and Lomandra Tanika were chosen for the above reasons and once planted, were quick to establish.  The plants are still performing in drought conditions with no additional irrigation.

Victoria Street - Ballarat
Planting of Victoria St, Ballarat was carried out in January 2006.  Alliance Seeds planted out approximately 2.5 km of the main approach into the township from the Western Hwy.  As low growing plants were required as not to interfere with driver vision, this was a great opportunity for us to showcase our Ozbreed range of plants. 

The following Ozbreed varieties were used for this project; Themeda Mingo, Pennisetum Black Lea, Dianella Little Jess, Dianella Little Rev, Dianella Breeze, Lomandra Tanika,  Lomandra Katrinus as well as Isolepis nodosa.  Plants were selected that would cope with frosts and prolonged periods of dryness without irrigation, that would establish quickly for visual impact and reduce maintenance. An extremely low plant mortality rate was achieved even though planting took place in the hottest and driest time of the year.
