Work is under way at Sanatorium Reserve where contractors have been removing bamboo and other pest plants from the area.
The work is the start of a project aimed at returning the area to its former glory as a nationally significant ecological and geothermal reserve, Rotorua Lakes Council said .
The first phase of the restoration work entails removal of pest vegetation and animals and rubbish clean-ups.
The second stage will involve working with iwi, conservation and community partners. It will focus on revegetation and ideas for infrastructure enhancement as well as cultural and ecological interpretive signage.
Weed control operations are under way with significant amounts of bamboo already cleared.
