In its new position, the council said the sculpture would provide a “valuable habitat for wildlife” and allow people to still enjoy the artwork.
Councillor Charles Quinn said: “The Hull 2017 tree sculpture has become a much-loved feature of Pearson Park, representing our city’s creativity and culture.
“By laying the sculpture on the ground, we’re ensuring it continues to have a lasting legacy as it naturally transforms into a wildlife haven.
“This way, visitors can continue to enjoy the sculpture, remembering the spirit of Hull 2017 and what it meant for our city.”
