Low to trap sea life in ghost nets

A CAPE York biologist was gearing up for more sea turtle rescues and deaths yesterday as a tropical low hit northern parts of the peninsula. Brett Leis said conservationists would patrol remote beaches once the tropical low had passed over and...read more...

Milman Island Hawksbill Turtle Research 2010

In 2010, Cape York Sustainable Futures has teamed up with the Sea Turtle Foundation and Queensland Parks and Wildlife Service for the Milman Island Hawksbill Turtle Research Project. We have been busily assisting in organising logistics and gear for this important conservation project. The first research team left yesterday and are now on their way north to the top of the Great Barrier Reef on the cargo ship 'Trinity Bay' and will land on the island in 2 days. They will be joined by project staff in 2 weeks time.

Research into the nesting demographics of hawksbills has been occurring annually on the island for the past 15 years. This is the longest running study of its kind. Hawksbill turtles are listed as 'Critically Endangered' under the IUCN. In 2010 the team will further the understanding of the impacts of climate change on the island.

In addition, Traditional Owners and Injinoo Rangers will be assisting with the study and will be provided with training in sea turtle biology and assessment. Additionally, Torres Strait Islander students from Thursday Island will also be involved in the monitoring of the turtles.

Climate change could impact turtle gender: scientist

News article: ABC News Fri Jan 8

There are concerns climate change could affect turtles that travel from across the Asia Pacific to nest on islands off the north Queensland coast.

A group of scientists is today heading to Milman Island off Cape York to continue a long-term research project.

David Roe from the Sea Turtle Foundation says the animals' gender is determined by sand temperatures.

Researchers hypothesise that climate change could lead to a shortage of male turtles.

"Other dangers that we are more fearful about ... is that rising sea levels and increased storm frequency and ferocity which are also predicted through climate change can lead to the erosion of nesting beaches and indeed the swamping and destruction of turtle nests," he said.

Cape York: one of the most remote places on Earth

Cape York was recently named in the top 10 most remote places on earth. See article at: http://www.toptenz.net/top-10-most-remote-places-on-planet-earth.php


Indeed, as part of the sea turtle project we spend a lot of time travelling up Cape York and significant time in the field in very remote locations. For this reason there are a lot of logistics in planning field trips. We have to ensure that our equipment is up to scratch and safety protocols are in place, particularly as we spend a lot of time around saltwater crocodile habitat!

24,000 pigs eradicated on western Cape York to protect sea turtles

In one of the largest culls of it's kind, over 24,000 pigs have been removed in 3 years from the the coastal areas of western Cape York as a result of aerial culls undertaken to protect important sea turtle nesting beaches. Cape York Sustainable Futures has worked in collaboration with highly trained marksmen from the Cape York Weeds and Feral Animal Program to remove pigs from priority areas. These culls have been undertaken on land managed by Injinoo, Mapoon, Napranum, Aurukun, Kowanyama and Pormpuraaw with the support of the communities and traditional owners of these areas. Aerial culling is one of the most cost effective options in remote areas such as Cape York.

Sea Turtle Conservation Officer Brett Leis says "Surveys have shown that these culls have been successful in reducing pig predation on turtle nests. However the effort needs to continue and it is important that other techniques, such as baiting, are used to complement the aerial shoots".

2010 Year of Biodiversity

Due to human activities, the world's animal and plant species are disappearing at a rate some experts put at 1,000 times the natural progression marking 2010 as the International Year of Biodiversity - the variety of life on Earth.

A new research report from the International Union for the Conservation of Nature (IUCN) has outlined ten species likely to be hardest hit by climate change. The leatherback sea turtle and koala are among these most vulnerable species.

Sea turtles are being affected by rising sea levels and increased storm activity due to climate change which destroys its nesting habitats. Temperature increases may lead to a reduction in the proportion of males relative to females.

"Sea turtles are truly resilient creatures that have survived millions of years of global change, yet today they are in decline pan-globally due to the unprecedented pace of climate change and other human-generated impacts," said Dr. Roderic Mast, co-chair of the IUCN SSC Marine Turtle Specialist Group and vice president of the nonprofit Conservation International. "Sea turtles are bellwethers, whose message to man is that slowing and reversing climate change is urgent."
