[1][2] The species is found in dry grassland habitats[1] and requires the maintenance of inter-tussock spaces for its establishment and persistence.

[2] A number of anthropogenic factors have contributed to the species decline such as impacts from land clearing, road construction and maintenance, and herbicide application.

[8] Tasmanian Lowland Native Grasslands and are classified as a nationally threatened ecological community, and critically endangered in Tasmania.

Since European settlement in Tasmania in 1803[9] there has been extensive clearing of Lowland Native Grasslands amounting to the decline of many species found within them, including S. fasciculatus.

[2][7] There is also a focus on controlling introduced deer populations in the Australian Alps to preserve S. fasciculatus and other species and communities that are threatened by their presence.
