Road and powerline impacts


Impacts of roads and powerlines on the Wet Tropics World Heritage Area, Stage 2

By Miriam Goosem and Steve Turton

Through the Wet Tropics Plan, a number of roads and tracks have been closed or have restricted access because of their potential impact on flora and fauna. As part of a consultancy for the Wet Tropics Management Authority, Rainforest CRC researchers have monitored these impacts on native flora and fauna and the spread of exotic weeds and other pest organisms for a number of years.

This report details the results of the first two years monitoring and includes an assessment of the impact of road/track closure/opening on the Wet Tropics, an assessment of road/track damage through increased use and indicators of impacts of road opening/closure for future monitoring.
