The Olympic Delivery Authority (ODA) has announced the landscape and public realm contractor to manage the north section of the park, with sub-contracts for tree and plant supply to follow.
The appointment of Edmund Nuttall ends months of speculation over the plants required for the site. The company will now begin to procure suppliers and sub-contractors.
The first contracts managed by Edmund Nuttall will be those for the supply of trees and plants across the site, to be issued by the end of this year. Work will start on site in spring 2009.
LDA Design and Hargreaves Associates have created a plan for the Olympic Parklands, which will be submitted for planning permission next month.
ODA head of parklands and public realm John Hopkins said: "This will leave a fantastic new green space legacy. The project is on track and we will be working with our contractor to quickly buy the tree and plant packages."
Edmund Nuttall will oversee the transformation of 40ha of former industrial land. A contract for the landscaping of the south of the park is to be issued later this year.
