Solanum opacum (greenberry nightshade) is a sprawling annual or short-lived herb, predominantly associated with poorly-drained swamp forests and riparian areas. The species is known from 9 sites across northern Tasmania and the Bass Strait islands with historical land clearing likely contributing to its very disjunct distribution. The data suggest that the total population in Tasmania is small, and likely to number fewer than 250 plants and occupy well less than 1 ha in total, placing it at risk from chance events, the risk exacerbated as plants may not be seen or only persist in low numbers in between disturbance events. Plants could be accidentally removed as they are similar to the weed Solanum nigrum (black nightshade). The most important needs of Solanum opacum are periodic disturbance for recruitment, and to prevent overgrazing by stock, competition from weeds, and destruction of known and potential habitat by clearing or degradation.

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. ​​​​​
