Brown Rat

Brown Rat (Rattus norvegicus) is classified as Least Concern (LC) on the IUCN Red List. Widespread and abundant across its range, with stable populations and no immediate conservation concerns.

Cobberas Grevillea

Cobberas grevillea (Grevillea brevifolia) is a low-growing, spreading shrub in the family Proteaceae, endemic to a restricted area in the Cobberas–Tingarringy region of the Victorian Alps and adjacent New South Wales ranges in southeastern Australia. It grows in subalpine to montane heath and rocky outcrops at elevations above 1,000 metres, where it is associated with snowpatch vegetation and exposed rocky ridgelines. The species produces small, narrow leaves and clusters of red and cream spider-like flowers typical of the diverse genus Grevillea, which is one of the largest genera in the Proteaceae family. Flowers are an important nectar source for honeyeaters and insects during the short alpine summer. Cobberas grevillea is assessed as Vulnerable by the IUCN, reflecting its extremely restricted range of only a few square kilometres of suitable habitat and vulnerability to altered fire regimes, climate change—which is shifting snowpack dynamics and vegetation zones upward—and disturbance from feral horses, which damage subalpine vegetation through grazing and trampling. Conservation measures include habitat monitoring within alpine national parks and management of introduced herbivores.
