Former Greens leader Bob Brown has been arrested for the second time in two days while protesting against logging in northeast Tasmania.
The former senator and two other activists were taken into custody by police on Wednesday, the Bob Brown Foundation said in a statement.
The Eastern Tiers forest is home to the critically endangered swift parrot, with fewer than 300 remaining in Australia, according to a recent study.
Dr Brown was arrested on Tuesday in the same area and accused of trespassing.
He has been granted bail and will appear in Hobart Magistrates Court in March, the foundation says.
"I slept out last night under a logging bulldozer which had invaded the Lost Falls forest," the 75-year-old said.
"We saw owls and I heard one of the 300 remaining swift parrots.
"It was rainy with temperatures down towards zero, but we were content just to know the swift parrot habitat destruction was slowed by us being there."
Dr Brown has taken state-owned logging group Sustainable Timber Tasmania, and the state and federal governments, to the Federal Court over forestry agreements his foundation claims are unlawful.
The full Federal Court hearing in Melbourne is examining whether Tasmania's 20-year regional forest agreement, renewed in 2017, is invalid.
The judges have reserved their decision.
Three years ago, Dr.Brown won a High Court bid to overturn Tasmania's anti-protest laws he labelled as draconian.
