Gorse control to protect Mirbelia oxylobioides

In October 2015 we joined Threatened Plants Tasmania on a working bee at a rarely visited reserve near Elderslie. The aim of the working bee was to control gorse that threatens the only Tasmanian population of the sandstone bushpea (Mirbelia oxylobioides) and find out more about the flora of the site. One team headed up into the sandstone pavements to look for rare ephemerals (annual plants with very short lifecycles): the tiny daisy (Brachyscome perpusilla) and moss sunray (Hyalosperma demissum). The survey, while adventurous and rewarding, was only partly successful due to the very dry season, with one new site for the tiny daisy discovered. The core population of Mirbelia oxylobioides (sandstone bushpea) was in striking flower, and there was an unexpected bonus was a sea of yellow and white flowers on the reserve’s upper slopes, thanks to swards of Aotus ericoides (golden pea) and Boronia anemonifolia (stinky boronia). Back on the flats of the Jordan, the weed control team inspected the great work of pakana services in cutting and poisoning the very large gorse plants, some of which had invaded the Mirbelia population. This team removed some small remaining gorse plants and re-recorded photopoint images to enable tracking of the effectiveness of the weed control. The weed control and working bee were supported by NRM South’s Naturally Inspired grants
