The ACT Greens say they would make Canberra an "urban biodiversity haven", as the battle over green spaces takes centre stage in the lead up to the October territory election.
Greens leader Shane Rattenbury said the party's $53 million plan would create neighbourhood forests and establish an urban wildlife corridors program.
Mr Rattenbury said the plan would form part of any parliamentary agreement the Green's made to form government with a major party.
The plan would increase funding to Namadgi National Park and for a range of community conservation groups.
It would see 10 new local Indigenous rangers employed to improve environmental management and restoration.
Mr Rattenbury said the plan would make the ACT a biodiversity hotspot and wildlife haven by protecting and expanding local habitats, tree hollows, food trees, and accessible water across the city.
"To ready our city for our new climate reality, we must act to protect our environment, with the same boldness and decisiveness as we have the COVID crisis," he said.
Opposition Leader Alistair Coe said the Greens had failed to deliver green space despite being part of government for the last 12 years.
"They've been propping up the ACT Labor party and have had a Greens minister as part of the government for the last eight years," he said.
"Under their watch, we've seen the tree canopy go backwards, trees get cut down, and entire suburbs get developed without trees."
Environment Minister Mick Gentleman said ACT Labor had delivered on protecting the environment over many years.
"We have some unique opportunities to look after this habitat in the ACT and [having] species such as the golden sun moth, earless dragons, legless lizard for example, means we need to set aside areas for them, and that's what Labor has been doing," he said.
