Chatham petrel population growing

Status (2012):Population (2010):Trend: Nationally vulnerable1,400 individualsImproving Probably once abundant throughout the Chatham Islands, human exploitation, habitat destruction and introduced predators saw the Chatham petrel restricted to Rangatira or Southeast Island by the time of its discovery in 1892.
