FOREST Rescue Australia's (FRA) Save the Numbats Warrup campaign headquarters in Greenbushes was raided by state security police.
FRA co-ordinator Simon Peterffy said on May 16 state security police arrived at the Greenbushes base with a warrant.
"The state security police had a warrant specifically for our lock-on devices," Mr Peterffy said.
"We've been trying to save the numbats from extinction and instead we're being hit very hard by police with arrests and never before seen fines in terms of how heavy they are.
"However we have to do the right thing, with what's honourable and do everything in our power to save the numbats by saving their habitats.
"They left with a trailer with a couple of our large lock-ons and half a dozen of the small ones," he said.
Mr Peterffy was not on site at the headquarters when the raid began and was instead in Warrup forest.
He returned at about 9am before the raid concluded.
"We are concerned at the involvement of a body such as state security, a branch of police that deals with terrorism and not with protest groups about environmental issues," Mr Peterffy said. "Now it's about the right to protest."
He said he was concerned at the "increasingly dark times" we lived in, with the proposed state anti-association laws looking like they will be passed by State Parliament and which will provide additional "draconian" powers to police against protest groups.
"It's dark days, because recently even without the anti-association laws yet through Parliament, we've been hit with prohibitive orders for the first time," he said.
"The Barnett government should realise that there is an election around the bend and Barnett appears sensitive to us highlighting issues not dissimilar to those issues that brought down the Court government," Mr Peterffy said.
Bridgetown lawyer Daniel Iacopetta expressed his concern at the erosion of civil liberties.
Police have not laid any charges in relation the items they removed from the Greenbushes headquarters.
