Scientific name: Persoonia acerosa
Common name: Needle Geebung
Other common names: Mossy Geebung
Conventionally accepted as Persoonia acerosa (CHAH 2010).
The Needle Geebung is a small, erect to spreading shrub up to 2 m tall with a greyish-brown stem. Young branchlets are smooth to sparsely haired. Its bright green, crowded pine-like foliage is a distinguishing feature. The small, smooth, needle-like leaves are channeled on the upper surface, 1.2–2.3 cm long, about 0.5 mm wide, and strongly incurved. When young, new leaves may be hairy but quickly become glabrous (smooth). Flower clusters are produced along leafy shoots, not at the branch tips, as in related species. The yellow tubular flowers are 8–10 mm, with small stalks 1–2 mm long, spreading to suberect, glabrous or sparsely hairy. Fruits are pear-shaped, yellowish-green with brownish-red markings, to 14 mm long and 10 mm in diameter (Blombery & Maloney 1992; NSW NPWS 2000ab; NSW OEH 2012g; Plantnet 2012; Weston 1995b).
The Needle Geebung has been recorded on Newnes Plateau in the north, Hilltop in the south, Lithgow/Jenolan in the west and Cordeaux Dam catchment in the east (ALA 2013; Smith 2007 pers. comm.). The species is mainly recorded in the Katoomba, Wentworth Falls and Springwood in the Blue Mountains (ALA 2013). The populations at Hilltop and Jenolan may be extinct (NSW NPWS 2000ac).
The Needle Geebung has been extensively surveyed, however large tracts of low quality suitable habitat have not been surveyed (NPWS 2000ac).
The Needle Geebung is known from the Blue Mountains National Park, one historical record from Kanangra-Boyd National Park and areas managed by Blue Mountains City Council at Woodford Dam, a reserve at Leura, Adelina Falls at Lawson and Hassans Walls Reserve at Lithgow (NSW NPWS 2000ab).
The Needle Geebung grows in heath, scrubby low-woodland or dry sclerophyll forest (Blombery & Maloney 1992; Harden 1991; NSW NPWS 2000ab; Weston 1995b). The species is found mostly on ridge-tops and plateau areas, growing in sandy topsoils over clayey subsoils (NSW NPWS 2000ab). Associated overstorey species include Silvertop Ash (Eucalyptus sieberi), Sydney Peppermint (E. piperita), Hard-leaved Scribbly Gum (E. sclerophylla) and occasionally Blue Mountains Mallee Ash (E. stricta) and Privet-leaved Stringybark (E. ligustrina) (NSW NPWS 2000ab). Understorey species include Mountain Devil (Lambertia formosa), Flaky-barked Tea-tree (Leptospermum trinervium sensu lato), Finger Hakea (Hakea dactyloides sensu lato), Narrow-leaf Platysace (Platysace linearifolia), Conesticks (Petrophile pulchella), Sunshine Wattle (A. terminalis) and Blunt Leaf Wattle (A. obtusifolia) (NSW NPWS 2000ab).
The Needle Geebung occurs on clayey sandstone, sandstone admixtures, laterite and gravels, which are well drained but infertile and often stony (Blombery & Maloney 1992; Harden 1991; NSW NPWS 2000ab; Weston 1995b). The species is recorded from 550–1000 m above sea level and prefers areas with reduced competition and an open canopy, such as roadsides and trails (NSW NPWS 2000ab; NSW OEH 2012g).
The distribution of the Needle Geebung overlaps with the following EPBC Act-listed threatened ecological communities:
- Shale/Sandstone Transition Forest
- Cumberland Plain Shale Woodlands and Shale-Gravel Transition Forest
- Turpentine-Ironbark Forest in the Sydney Basin Bioregion
- Temperate Highland Peat Swamps on Sandstone.
The Needle Geebung flowers from December to May (Bernhardt & Weston 1996; Weston 1995b) and is pollinated by native plaster bees (Leioproctus spp.) and reed bees (Exoneura spp.) (Bernhardt & Weston 1996). The species may hybridise with the Broad-leaf Geebung (Persoonia levis), the Myrtle Geebung (P. myrtilloides) and possibly the Narrow-leaved Geebung (P. linearis) where they grow together (Plantnet 2012). The species may live for up to 20 years (NPWS 2000ab).
The Needle Geebung is fire sensitive (NSW OEH 2012g). Adults are generally killed by fire. Recruitment is solely by seed with seedlings seen most frequently after disturbance or fire events. Disturbance is not essential for germination, although undisturbed sites tend to support lower numbers, while sites such as ridge-top trail margins can support up to 40 plants over a few hundred metres (NSW NPWS 2000ab).
The Needle Geebung is readily identified by the channel on the upper surface of its leaves (Waratah Software undated) and can be surveyed at any time of the year, although identification is easier during the flowering period. Disturbed margins (road and trail verges), the edges bushland that have been cleared and, in particular, previously cleared ridges are more likely to support the species, however effort should not be restricted only to these areas (NPWS 2000ac).
Identified threats to the Needle Geebung include (NSW NPWS 2000ab, 2000ac; NSW OEH 2012g):
Loss and degradation of habitat
Clearing for urban development and small rural lots in the upper and central Blue Mountains is a threat to populations and the habitat of the Needle Geebung. As the species prefers disturbance margins such as trail edges, it is at risk of continued frequent maintenance activities preventing seedbank establishment and causing local extinction.
Infection by the root rot fungus Phytophthora cinnamomi
This disease is known to kill individual Needle Geebung plants. The fungus may be transmitted into uninfected populations by maintenance and slashing activities, recreational vehicles or bushwalkers.
Inappropriate fire regimes
Hazard reduction burns and other anthropogenic ignitions have increased fire frequency and may cause localised extinction.
Recovery actions for the Needle Geebung include (NSW OEH 2012g):
- Protect known habitat areas from clearing and disturbance.
- Following burning, protect populations (where possible) from further fires until plants have reached reproductive maturity.
- Control threatening weeds where necessary. Avoid spraying weeds close to Needle Geebung plants to ensure they are not impacted by poison.
- Mark Needle Geebung sites and potential habitat onto maps used for planning road maintenance work.
- Erect on-site markers to alert maintenance staff and road-users to the presence of this species.
- Ensure that personnel planning and undertaking hazard reduction burns are able to identify the species and are aware of its habitat.
- Monitor populations for the impact of Phytophthora cinnamomi.
Management plans relevant to the Needle Geebung are at the start of the profile. Other relevant documents include:
- Blue Mountains Plan of Management (NSW NPWS 2001v)
- Kanangra-Boyd National Park Plan of Management (NSW NPWS 2001u)
- Threat Abatement Plan for Dieback Caused by the Root-Rot Fungus Phytophthora cinnamomi (EA 2001m).
The following table lists known and perceived threats to this species. Threats are based on the International Union for Conservation of Nature and Natural Resources (IUCN) threat classification version 1.1.
