Micrantheum serpentinum is a straggly shrub in the Euphorbiaceae (spurge) family, restricted to ultramafics (Cambrian serpentinite) in Tasmania’s northwest. Habitat includes open low eucalypt woodland, shrubland and heathland, generally on lateritic soils, in a region with mean annual rainfalls exceeding 2000 mm. The main threat to the species is mineral exploration and extraction. The prolonged absence of fire also poses a threat, with localised impacts due to weed infestations and the construction and maintenance of roads and power easements.

Permit: A permit is required under the Tasmanian Threatened Species Protection Act 1995 to 'take' (which includes kill, injure, catch, damage, destroy and collect), keep, trade in or process any specimen or products of a listed species. Additional permits may also be required under other Acts or regulations to take, disturb or interfere with any form of wildlife or its products, (e.g. dens, nests, bones). This may also depend on the tenure of the land and other agreements relating to its management. ​​​​​
