Ecologist Mark Graham, whose 1000-acre conservation land at Billys Creek was ravaged, said the fires have severely affected the region's globally significant wildlife.

"This is the time of the year that maximum breeding activity and migration is happening," he said. "Because of these fires, habitat and biodiversity have been lost, as have sources of food and safe breeding places during this most sensitive season.

"Having these forests burning across such a broad scale and at such a high intensity means that most of the native birds, bats and insects that lived in these forests have had to fly elsewhere in order to survive."

He said that the forests of the Kalang Headwaters are an important refuge for these displaced native species, and on no account should they be logged.

"All unburnt, unlogged and intact native forests on the Mid North Coast now need to be retained and protected to ensure a future for our wildlife. Any logging of the Kalang Headwaters will take away this important unburnt refuge for our globally significant wildlife," he said.

"The Friends of the Kalang Headwaters call on the NSW government to permanently protect these remarkable forests in a conservation reserve."

A march will be held in Bellingen on Saturday October 19 to protest proposed logging in the Kalang Headwaters.

It will start at the football oval in Bellingen Park at 9.45 am and go down Hyde St.
