Two of four "tree-sitters" that were arrested while protesting the destruction of an 11-acre Arcadia oak woodland in January appeared in Alhambra Superior Court on Thursday and had their arraignment postponed until February 18. They are John Quigley, 50, of Glendale, and Julia Jaye Posin, 23 of Venice Beach. Travis Jochimsen, 28, of Lancaster and Andrea Bowers, 45 of Los Angeles, were also arrested but did not appear for arraignment.
