Some of the criminal charges levelled at former Greens leader Bob Brown over anti-logging protests in Tasmania have been dropped in court.
Dr Brown was arrested twice in two days in December at rallies on forestry land in the state's Eastern Tiers which is habitat of the critically endangered swift parrot.
He was facing trespassing charges in relation to both days.
But in Hobart Magistrates Court on Thursday charges for the second day were dismissed because no evidence would be tendered. The remaining offence was adjourned until July 22.
Dr Brown, who has yet to enter a plea to the charge, listened to the hearing via phone.
One trespassing charge against Bob Brown Foundation campaign manager Jenny Weber in relation to the protests was also dismissed.
The Bob Brown Foundation is involved in a separate legal fight aimed at ending native forest logging in Tasmania.
In February, the Federal Court dismissed the conservation foundation's case that argued Tasmania's regional forestry agreement was invalid because it did not properly protect threatened native animals.
The foundation is seeking to appeal the decision in the High Court. It argues native forest logging has put the swift parrot at further risk.
A study found there were fewer than 300 of the migratory birds remaining in Australia.
