Executive Summary This report provides an overview of the conservation status of roadside remnant vegetation in the Shire of Kalamunda. The report primarily gives detailed results of the roadside vegetation survey and is accompanied by management recommendations. It also describes the natural environment in Kalamunda, legislative considerations and threats to conservation values. Aware of the need to conserve roadside remnants, the Shire of Kalamunda liaised with the Roadside Conservation Committee (RCC) to survey roadsides in the Shire. Surveys to assess the conservation values of roadside remnant vegetation were conducted between May 2013 and February 2015. Over 220km of the Shire’s rural roadsides and roadsides adjoining bushland (including national parks, nature reserves & shire reserves) were assessed by the RCC for their conservation status, and maps were produced via a Geographic Information System (GIS). Roadside locations of six nominated weeds (African lovegrass, eastern states wattles, fleabane, plantain, tagasaste and Victorian teatree) were also recorded and mapped. The results of the survey indicated that 42% of the roadsides
