[edit] Water Supply Catchments

[edit] Overview

90% of Melbourne's water is sourced from uninhabited forests in the Yarra Ranges.In excess of 157 thousand hectares is reserved for water catchment. These forests primarily consist of Mountain Ash. Catchment areas have been closed to the public for over 100 years.[3]

[edit] Clearfell logging in catchment areas

Clearfell logging is permitted in these catchment areas which in turn is reducing Melbourne's water supply.[4][5] It is estimated that 30 thousand megalitires of water could be saved per annum by phasing out logging. This represents 6% of Melbourne's annual usage.[6]
