Population boom for threatened bird species. 10/01/2006. ABC News Online


University of Tasmania researchers have discovered populations of the threatened great southern petrel in the Antarctic Frazier Islands are at their highest level in 50 years.
They have just visited the breeding site for the birds, which is near Australia's Casey research station, for the first time in five years as part of a population study.
Researcher Dr Eric Woehler says it is the first contact humans have had with the site in that time.
"The increase, we believe, is partly due to the fact that these islands are now restricted access," he said.
"In the past it was much easier to go out to the islands, to land helicopters.
"In some cases, some of the actual science that was done is actually thought to have contributed to the population decrease."
Great southern petrels are particularly vulnerable to long line fishing operations.
