DOC later located a dead juvenile red-billed gull. DNA analysis of the gull found at the scene confirmed the presence of dog saliva and deep puncture wounds. Red-billed gull populations have recently suffered dramatic decline and their conservation threat status changed to 'nationally vulnerable' - the same threat status as North Island brown kiwi.
"This prosecution sends a clear message to dog owners that their pets need to be under control at all times," said DOC ranger Caraline Abbott.
"Sulphur Bay is an important site for many threatened bird populations including dabchicks, black-billed gulls and red-billed gulls. While it may seem that there are many gulls around New Zealand, populations are reducing dramatically - largely through predation by stoats, rats and feral cats."
DOC and Rotorua Lakes Council are developing a community led conservation project around Sulphur Bay which will help reduce predator populations and support the wildlife refuge. It is thought increased biodiversity around the Nature Heritage Trail will increase business and tourism opportunities in this area.
Under council bylaws, dogs are prohibited from reserves unless set apart as Dog Exercise Areas. For more information contact Rotorua Lakes Council.
