Aboriginal forest protester Ruth Langford has sought a two-month adjournment to build her defence relating to trespass events which allegedly occurred earlier this year.

Ms Langford appeared via phone in the Hobart Magistrates Court on Thursday regarding two counts of trespassing on land and one count of failing to comply with a request from an authorised officer.

It is alleged the Yorta Yorta and Dja Dja Wurrung woman, who pled not guilty to the charges in May, trespassed in January this year at a Snow Hill logging coupe in the Eastern Tiers forest, known as SH067C, as well as during a protest at a Lonnavale logging coupe in April.

The third charge of allegedly failing to comply with a request from an authorised officer also relates to the Lonnavale coupe, known as RU030E.

Defence lawyer Richard Griggs told the court he had only received instructions from Ms Langford recently, and would required additional time to put together the 55-year old's defence.

"There are two reasons, one is that there is a matter of an outstanding map to be disclosed by the prosecution," Mr Griggss said, The Mercury reports.

"Secondly, I recently received instructions from Ms Langford on her defence – recently as in the last 24 hours.

"This requires a significant amount of material that would need to be put together for that defence and then served on the prosecution."

In response, the prosecution questioned the need for another adjournment, stating Ms Langford's previous lawyer, Roland Browne, intended to provide a defence in July of this year.

Magistrate Catherine Geason adjourned the matter until December 15, with Ms Langford bailed to appear via telephone on that date.
