More than 20,000 plants have been laid along Hawke's Bay's Karamu Stream and tributaries in the past month.
Public plantings have been held every weekend since May 26 as part of Hawke's Bay Regional Council's (HBRC) Plant Thru Winter programme.
Two more plantings were held at the weekend with 1000 plants going in at Whakatu on Saturday and 500 at Paki Paki yesterday.
HBRC open spaces manager Stephen Cave said the plantings have been a major project for Karamu Stream with a number of highlighted areas being prioritised in terms of water quality, habitat and community location.
"We've planted in excess of 20,000 plants on the Karamu Stream and associated tributaries."
