Activists have confirmed they will do everything they can to stop the logging.

Bridgetown-Greenbushes Friends of the Forest (BGFF) president Richard Wittenoom said the logging in Warrup was imminent.

However, he said Arcadia would be logged first.

"My understanding is Arcadia first, then Warrup 06 and later Warrup 08 and 02," Mr Wittenoom said.

Mr Wittenoom said in the near future the BGFF would further highlight to residents the impacts this logging will have for the region's forestry and disseminate information on climate change impacts and national park issues.

Forest Products Commission (FPC) spokesman Peter Beatty confirmed approval had been granted to log both Warrup and Arcadia forests.

"In line with previous advice we have given to a number of parties, harvest and roading operations for both coupes (Warrup and Arcadia) have been approved (for logging) this summer," Mr Beatty said.

“Planning and approval processes have been completed.

“The combined area of Warrup and Arcadia coupes to be harvested is about 470 hectares.

"Both areas are important for log supply to our sawmill customers."

Conservation groups state wide have committed to protecting Warrup and Arcadia at all costs, even if it means arrests.

Forest Rescue co-ordinator Simon Petterfy, recently home after his 'visit' to the Shonan Maru said the group would stand in the way of loggers in Warrup.

"Forest Rescue will now focus on what it does always and return to saving the forests," Mr Petterfy said.

"If push comes to shove with Warrup and any other icon blocks we will certainly engage in our non-violent direct action."
