Former Greens leader Bob Brown has been arrested for trespassing while attempting to halt logging in the northeast Tasmanian forest.
The 75-year-old former senator is seen being taken into custody on Tuesday morning in the Eastern Tiers forest in a video released by the Bob Brown Foundation.
"I've just been arrested for trespassing on my own public land as a Tasmanian and as an Australian," Dr Brown says in the video.
He was later granted police bail.
Greens Senator Peter Whish-Wilson and Tasmanian Greens leader Cassy O'Connor were moved on after being given a police direction, while three other people remained locked onto logging machinery, according to the foundation.
In a statement, Tasmania Police confirmed they had arrested and charged three people following a protest in the Lake Leake area.
Two women, aged 57 and 49, were also charged with trespass and bailed.
The forest is home to the critically endangered swift parrot, fewer than 300 of which could remain in Australia according to a recent study.
Dr Brown earlier this month took state-owned logging group Sustainable Timber Tasmania, and the state and federal governments, to the Federal Court over forestry agreements his foundation believes are unlawful.
A 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.
Dr Brown in 2017 won his High Court bid to overturn Tasmania's anti-protest laws.
The landmark case stemmed from Dr Brown's arrest while filming a video about an anti-logging protest at Lapoinya State Forest, in the state's northwest, in January 2016.
