Project Twin Streams aims to recreate and restore ecological corridors along the streams that flow from the forest-clad Waitakere Ranges, through the rural and urban parts of West Auckland, to the Waitematā Harbour. Functional ecological corridors contain healthy, self sustaining vegetation communities that function both as habitat for native fauna, and areas which fauna can move through the landscape. For this reason an assessment of Project Twin Streams needs to look at changes in terrestrial biodiversity (both plant and animal), as well as water quality and in-stream habitat.
The historical investigations of terrestrial fauna and flora in the PTS area are summarised in Table 1 . Envirologic Limited initiated the first terrestrial monitoring programme in 2004, which ran for four years. More recently Boffa Miskell (2010) and Bioresearchers (2012) have completed monitoring of birds and bats respectively.
