The Bolivia Wattle is an erect shrub or spreading tree, 3-15 m high with firm, grey-green phyllodes (Harden 1991; Tame 1992; Quinn et al. 1995; Steenbeeke 1998; NSW NPWS 2003m) and golden yellow flower spikes (Orchard & Wilson 2001a).
Occurs on the Northern Tablelands, NSW, on the Bolivia Ra., near Tenterfield, from Bluff Rock to Bolivia Hill (Hunter & Earl 1999; Orchard & Wilson 2001a).
The species occurs frequently in the granite belt, too abundantly to establish absolute numbers (Hunter & Earl 1999). Large areas of uncleared or slightly disturbed granite hills occur in the Tenterfield area, however, extensive surveys of granite outcrops by J.T. Hunter did not locate additional populations (Quinn et al. 1995).
The species is reserved in Bolivia Hill and Bluff River Nature Reserves (NSW NPWS 2003m).
Summary of populations as in Quinn et al. (1995):
|Pop. no.||Location||Tenure||Date surveyed - no. of plants||Comments|
|1.||Bolivia Hill||private property on the N slope of the range||07/05/1995 - 2000+||Population in good health.|
|2.||Bolivia Hill||private property on the S side of the range||15/09/1994 - 500+||Population health very poor, plants dead and stressed from drought.|
|3.||Sailor Jack||Back Ck area NW of Tenterfield||1992 - 200-500||-|
|4.||Bluff Rock||10 km S of Tenterfield||1994 - no data||-|
The species occurs amongst granite outcrops, on hillsides at altitudes of 700-900 m asl (Harden 1991; Tame 1992; Quinn et al. 1995; Steenbeeke 1998). Grows in crevices and shallow basins where some soil has accumulated (Quinn et al. 1995). The soils are sandy and infertile (Steenbeeke 1998; J.T.Hunter 2000, pers. comm.; Orchard & Wilson 2001a). It is most common on southern aspects (Hunter & Earl 1999).
It occurs in dry sclerophyll forest (Harden 1991; Steenbeeke 1998), open Eucalyptus-Callitris woodland and dry heath (Orchard & Wilson 2001a) in tall scrub, frequently being dominant or subdominant. In parts of Bolivia Hill, it dominates the tall shrub stratum below an open canopy of taller Acacia adunca, in an unusual layered scrub/low open forest community. The Sailor Jack population forms an understorey in dry sclerophyll forest. Associated species at Bolivia Hill include Eucalyptus prava, E. andrewsii, Callitris endlicheri and A. adunca (Quinn et al. 1995).
The flowers are borne Aug.-Oct. (Orchard & Wilson 2001a). Fruits are borne Oct.-Nov. (Quinn et al. 1995), or during summer (Steenbeeke 1998).
The species regenerates well along roadsides at Bolivia Hill (Quinn et al. 1995).
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.
