Almost one million native plants grown in house for Northern Connector project

The Northern Connector Project is a six-lane, 15km motorway in South Australia. Around 80,000 native trees and shrubs were planted in 2018, with an additional 870,000 plants to be planted by November this year. Nearly all of these trees have been grown at Ecodynamics’ own nursery facility. All are hand planted, with 6 people on the planting crew, and 2 people watering. On average, our crew’s planting rate is 30,000 plants per week.

Keeping it local

South Australia’s Department for Planning, Transport and Infrastructure’s official landscape specification required all landscape companies working on DPTI projects to use a Belgian soil conditioning product called TerraCottem. Ecodynamics submitted the tender for the Northern Connector project and put forward a preference to use a local South Australian product known as GOGO Juice. This is the first time that DPTI have approved such a change in specification on an infrastructure project since the TerraCottem requirement was introduced.

10 litres of Neutrog’s GOGO Juice solution has been applied to every newly-planted tree on the Northern Connector, with a total of 22,000 litres delivered in 1000 litre shuttles. It’s also used on other projects, and in the Ecodynamics plant nursery.


  • More than 900,000 Australian native trees, plants and shrubs are being planted along the 16-kilometre length of the Northern Connector as part of the $885 million project.
  • About 900,000 shrubs and ground covers and 30,000 trees and taller shrubs will line the road, with 95% being Indigenous to the local area and having been grown from seeds and cuttings collected from local remnant sources.
  • The project team, led by Lendlease and landscape partner Ecodynamics, have been mindful of the project’s commitment to invest in local industry during landscaping. This included seeking a change of department specification for use of a European-made fertiliser to a South Australian product, GOGO Juice, made locally in Kanmantoo by Neutrog.
  • This process has ensured the project continues to support local investment, with 91% of all Northern Connector Project spend to date being on South Australian businesses.
