Mr Byrne said the botanist found Crepe Myrtle, Cat’s Claw Creeper and Fishbone Fern in the nearby area by doing a survey from the road.
He said the botanist agreed with the proposition that plants and leaf material could flow down waterways, such as Kholo Creek.
Mr Byrne said Dr Guymer seemed to recall Kholo Creek as being a slow moving waterway.
He urged the jury to assess the time-lapse video tendered by the defence counsel which showed the creek’s tidal movements and debris floating in it.
“The movement of water up and down there is such that it explains… there was a substantial movement of water from a substantial catchment area,” he said.
Mr Byrne said the video may give the jury an explanation as to how fresh leaves were able to be found on the body some 10 days after it went missing.
He played the time-lapse video to the jury.
He told the jury to notice the amount, volume and size of the debris moved up and down Kholo Creek.
Mr Byrne pointed out a red pot plant that was deposited onto the bank and then removed again by the tide.
He said the evidence of Sen-Constable Ashley Huth was that the body was positioned below the high water mark at Kholo Creek.
Mr Byrne added that forensic pathologist Dr Nathan Milne could not exclude the possibility the body was moved by water, and pulled the jumper Ms Baden-Clay was wearing up around her neck.
He turns to the marks on the face of the accused.
Mr Byrne said Baden-Clay had never made any attempt to conceal the marks on his face or to give any explanation other than they were shaving scrapes.
“He’s the one who called the police to his home on the morning of the 20th of April,” he said.
Mr Byrne said the accused told everyone who asked what caused the marks and did so in an open and candid fashion.
