The Small-leaved Hazelwood is a tall shrub or small tree that grows to 7 m tall. The bark is smooth and dark-brown, with vertical fissures. The buds and branchlets are finely hairy. The leaves are thin, 2.5-7 cm long, 0.7-2 cm wide, lance-shaped and have a fine tip. The leaf margins are toothed, with 4-8 pairs of irregular teeth. Small cream flowers are clustered in racemes, and grow to red, fleshy and oval-shaped fruits (drupes) (Harden 1993a).

The Small-leaved Hazelwood is restricted to the Mount Warning caldera from Springbrook in Queensland, to the Nightcap Range in north-east New South Wales and within 40 km of the coast (Queensland Herbarium 2009c).

In New South Wales it is known from the Nightcap National Park, Mount Jerusalem National Park, Wollumbin National Park, Numinbah Nature reserve, Whian Whian State Conservation Area, Duroby Nature reserve and the Tweed and Brunswick Valleys. In Queensland it occurs in the Gold Coast Local Government Area, Mount Cougal National Park and Natural Arch National Park (Briggs & Leigh 1995).

The extent of occurence is estimated to be 600km². The area of occupancy is unknown (Queensland Herbarium 2009c).

The Small-leaved Hazelwood is known from approximately ten populations (Floyd 2008; Queensland Herbarium 2009c). There is limited information available on population numbers and the total population size is unknown. Labels of herbarium records include abundance measures of "very common", "infrequent", "occasional" and "rare at site", while one label says "only 1 or 2 plants seen" (Queensland Herbarium 2009c).

This species grows in subtropical and warm temperate rainforests on less fertile soils derived from rhyolite (Harden 1993a; NSW OEH 2012p) and occasionally in wet sclerophyll forest adjacent to rainforest. The altitude of known sites ranges from 140 m to 1000 m above sea level (Queensland Herbarium 2009c). 

Associated species include, at higher elevations, the Soft Corkwood (Caldcluvia paniculosa), Silky Oak (Orites excelsa) and Sassafras (Doryphora sassafras), and at lower elevations characteristic canopy species include the Blue Quandong (Elaeocarpus grandis), Red Carabeen (Geissois benthamii), Grey Possumwood (Quintinia verdonii) and Yellow Carabeen (Sloanea woollsii) (Barry & Thomas 1994; Quinn et al. 1995; Queensland Herbarium 2009c). Patches of tall Antarctic Beech (Nothofagus moorei) closed forest are also present (Barry & Thomas 1994; Queensland Herbarium 2009c).

Flowering has been recorded from August to September and fruiting has been recorded in December and February (Queensland Herbarium 2009c). It is unknown whether the species can reproduces vegetatively. Pollinating mechanisms and disturbance response are unknown.

Threats to the Small-leaved Hazelwood include (NSW OEH 2012p):

  • Localised extinction due to the small population size
  • Timber harvesting activities
  • Inappropriate fire regimes
  • Clearing of warm temperate rainforest for agriculture and other development
  • Accidental disturbance through road maintenance.

The following regional and local priority recovery and threat abatement actions have been identified to support the recovery of the Small-leaved Hazelwood:

  • Monitor known populations to identify key threats.
  • Monitor the progress of recovery, including the effectiveness of management actions and the need to adapt them if necessary.
  • Identify populations of high conservation priority.
  • Ensure road widening and maintenance activities (or other infrastructure or development activities) involving substrate or vegetation disturbance in areas where the Small-leaved Hazelwood occurs do not adversely impact on known populations.
  • Investigate formal conservation arrangements, management agreeements and convenants on private land, and for crown and private land investigate inclusion in reserve tenure if possible.
  • Minimise adverse impacts such as timber harvesting, clearing and development from land use at known sites.
  • Develop and implement a suitable fire management strategy for the Small-leaved Hazelwood.
  • Provide maps of known occurrences to local and state Rural Fire Services and seek inclusion of mitigative measures in bush fire risk managment plans, risk register and/or operation maps.
  • Raise awareness of the Small-leaved Hazelwood within the local community by encouraging people to identify new locations and participate in rehabilitation projects.
  • Undertake seed collection and storage.
  • Investigate options for expanding and reconnecting warm temperate rainforest remnants and linking, enhancing or establishing additional populations.
  • Implement national translocation protocols if establishment of additonal populations is considered necessary and feasible (TSSC 2008afk; NSW OEH 2012p).

Existing plans and managment prescriptions relevant to the Small-leaved Hazelwood:

  • Parks and Reserves of the Tweed Caldera – Plan of Management (NSW NPWS 2004a).
  • Border Ranges Rainforest Biodiversity Management Plan - NSW and Queensland (NSW DECCW 2010n).
  • Tweed Vegetation Management Strategy - August 2004 (Kingston, Turnbull & Hall 2004a).
