More than 120 volunteers planted 1800 trees, shrubs and ground covers in the Styx Mill Conservation Reserve.
A large group from the Filipino community and residents came out to help.
The result of these planting days is the ongoing re-establishment of native bush corridors restoring flora and fauna.
The increasing numbers of makomako (bellbird) heard in the area is just one clear sign city council parks rangers point to for the success of the initiative.
“Christchurch now has more native bush in it than it did in the 1850’s,” Trees for Canterbury trustee Anthony Shadbolt said.
