- Description
- Lastreopsis silvestris is a terrestrial fern with a creeping rhizome, 7 to 17 mm thick, and scaly at the apex. The scales are dark brown to black in colour, glossy, 5 to 6 mm long and 0.5 to 1 mm wide. The margins are entire. The fronds are moderately crowded. The stipe is 30 to 55 cm long, densely hairy throughout and scaly at the base. The lamina is 4-pinnate, pentagonal, 30 to 60 cm long and 22 to 60 cm wide, catadromous throughout, dark green and slightly glossy above, pale and dull beneath, thin, glabrous except for the veins. The rachises are densely hairy. The lower lamina surface is also scattered with scales. The ultimate segments are oblong, the margins are shallowly to deeply lobed, and the apex is subobtuse. The sori are numerous, and located between the margins and midrib. The indusium is dark brown and thin (Jones, 1998; Wilson, 2000).

- Habitat
- Lastreopsis silvestris grows in upland beech (Nothofagus) rainforest (simple or complex notophyll vineforest or moss/fern microphyll thicket) on basalt at altitudes from 900 to 1100 m. Associated species includes Nothofagus moorei with Lastreopsis microsora, Cyathea leichhardtiana, Blechnum sp. (Queensland Herbarium, 2012).
- Threatening processes
- There are no pressing threatening processes to Lastreopsis silvestris (e.g. landclearing or collecting); however, processes thought to present ongoing threats to this species include: damage from irregular storms that open the canopy; and global warming may reduce ecological fitness (nowhere to migrate to) for this high altitude species that is restricted to beech forest (DERM, 2008; Hughes 2003). There are no measures currently taken to reduce these threats (DERM, 2008).
- Status notes
- Lastreopsis silvestris is listed as Vulnerable under the Queensland Nature Conservation Act 1992.
- Management recommendations
- Lastreopsis silvestris requires accurate survey to determine the number of subpopulations, geographical range, area of occupancy and number of individuals. There is little or no information available on the genetics, reproductive biology, dispersal, recruitment or population structure of this species (DERM, 2008).
- Notes
- Occurs in the following Queensland pastoral districts: Moreton, South Kennedy. Also occurs in New South Wales.
