Three Hummock Island - 2006

Situated 45 km off the northwest coast of Smithton, Three Hummock Island is one of the larger of twelve islands and rock stacks in the Hunter Island group. Until this survey, biological work was patchy although a number of important species were known to have occurred on the island.

Three Hummock Island Survey

In December 2006, twelve wildlife scientists, two New Zealand volunteers and two Parks and Wildlife Service staff conducted an eight day integrated biological survey using a wide range of techniques. Previously mapped vegetation communities were intensively ground-truthed to update the TASVEG map. Assessments were made on species of threatened flora and fauna known or suspected to be on the island and a determination made as to whether Three Hummock Island would be suitable as a relocation site for Tasmanian devils free of the deadly facial tumour disease.

Survey Highlights

  • A comprehensive list of 67 bird species was made but did not include threatened species such as Fairy tern, Forty-spotted pardalote or Orange-bellied parrot despite targeted searches.
  • A range of mammals were identified including Long-eared bats, Forester kangaroo, Brush-tailed possum, Ring-tailed possums and Eastern pygmy possum.
  • Over 3,000 invertebrates were collected by various trapping methods and sorted into either order, family or species level.
  • Previously recorded Wedge-tailed eagle nests were not re-located, however, two active White-bellied sea-eagle nests and a recently used Swamp harrier nest were found.
  • Incidental observation of Tasmanian pademelon suggested a significant reduction and potential population crash.
  • This we know: The earth does not belong to man, man belongs to the earth. All things are connected like the blood which unites us all. Man did not weave the web of life, he is merely a strand in it. Whatever he does to the web he does to himself.

  • The human brain now holds the key to our future. We have to recall the image of the planet from outer space, a single entity in which air, water, and continents are interconnected. That is our home.
