The Blue Mountains Conservation Society is "very disappointed" by the snub from Macquarie Liberal candidate Sarah Richards who was the only candidate not to answer their federal election questionnaire.
The Society asked Macquarie candidates just one question: "What is the biggest threat to the Greater Blue Mountains World Heritage Area, and what should be done to address it?"
Out of the five candidates, four responded - Susan Templeman (Labor), Kingsley Liu (Greens), Greg Keightley (Animal Justice Party) and Tony Pettitt (United Australia Party).
Sarah Richards (Liberals) provided no response, nor did she respond to the Gazette's request for comment.
Recently elected Society president, Lachlan Garland, said: "We thank the candidates who responded for their thoughtful answers. However, we are very disappointed the Liberal candidate did not provide a response, given the protection and management of the Greater Blue Mountains World Heritage Area is such a vital issue for our local community."
All who responded identified climate change as the major threat to the area, including increased and more intense bushfires and impacts on fauna and flora.
