On route to Karkar Island, we asked the pilot if he would divert over the actual crater of Mt Uluman, the volcano in the centre of Karkar Island that erupted in 1974 and 1979, and threatens to erupt again. As the weather was relatively good he agreed and our circuling of the crater gave Dave and myself ample opportunities for photography. Jasper cowered on the floor of the aircraft, he did not like the volcano.

We then headed for the Kinim airstrip north of Kaviak Plantation, our usual base, coming in from the north due to our volcano over-flight.

We based as usual at the Kaviak guest house, courtesy of the Middleton family who have been long-time supporters of our venomous snake and snakebite fieldwork.

In 2008 we were again assisted by Timothy, a local plantation worker, and of course our own nambawan snekman Jasper.

The main purpose of the 2008 visit to Karkar Island, as with previous visits, was to collect specimens of New Guinea small-eyed snake (Micropechis ikaheka) for snakebite research. The second quest species was the Karkar population of the Smooth-scaled death adder (Acanthophis laevis). The third purpose was an ongoing survey of the herpetofauna of Karkar Island.

Plantation workers assist in the snake hunts... but immediately break to cook and eat any rats or bandicoots flushed from the husk piles.

Two large species of stick insects (Phasmatidae) were found in the vegetation on Karkar Island, the Giant spiny stick insect (Eurycantha calcarata), a species considered closely related to the almost extinct Lord Howe tree lobster (Dryococelus australis), and the Giant winged stick insect (Phasma gigas), a member of a group of phasmids thatare thought to have re-evolved wings after loosing them some 50million years previously.

The week on Karkar was soon over and we headed back to Madang and hence to Port Moresby.
