originally assessed the brown wood rail as Threatened but since 1994 has classed it as Vulnerable. It is known from only a small number of locations. Its estimated population of 1000 to 2500 mature individuals is believed to be decreasing due to "rapid rates of habitat destruction".[ "There is an urgent need for further investigation of its status and natural history."][
