Chief Minister Howard Quayle announced government’s plan to create the woodland in June 2019, a month after it pledged to reach net-zero emissions by 2050.
More than 70,000 trees have been planted by local contractors since February this year.
The project is being carried out by the Department of Environment, Food and Agriculture and funded by the Cabinet Office’s climate change transformation team.
The Chief Minister said: ’I am delighted to see such progress as we acknowledge Earth Day 2021.
’This year’s theme is restore our earth - and this project is helping to do just that.
’The new woodland will create important habitat, boost carbon capture and create a new amenity for islanders to connect with nature and boost wellbeing.
’We can’t do much about the weather and the remaining planting will take place at the earliest opportunity.’
The 45 hectare (111 acre) site has been planted mainly with a mix of broadleaf species including Aspen, Willow, Sycamore and Oak.
Environment Minister Geoffrey Boot said: ’The planting will create a diverse habitat for many species, and at the same time enhance our Biosphere and boost natural carbon capture. It will benefit people and wildlife for generations to come.’
The People’s Wood will open to the public once the necessary infrastructure has been completed, although the planting will take many years to mature.
The site will be linked to the island’s coastal path. Seating will be installed among the trees and at points where people can enjoy panoramic views towards Castletown.
