Scientific name: Acacia bakeri
Gazetted date:
17 Nov 2000
Profile last updated:

Description
Marblewood is a tree of 5 – 30 m with wrinkled bark and a rounded canopy that is much darker and denser than that of most wattles. Its curved leaves are broad and dark green, with three to four prominent longitudinal veins, and thickened veins around the edges. The flower heads are small, round, and pale or golden yellow, and are followed by large bunches of flat, brown seed-pods containing several black seeds.
Distribution
Restricted to coastal south-east Queensland and north-east NSW, where it occurs north from Mullumbimby. Most plants are on private property.
Habitat and ecology
- Marblewood grows in or near lowland subtropical rainforest, in adjacent eucalypt forest and in regrowth of both.
- It usually occurs in the understorey but may occur as a large canopy tree.

Threats
- Loss of habitat from agricultural development.
- Loss of habitat through land development.
- Private land forestry activities.
- Fire, which kills adult trees and encourages weed growth.
- Invasion by weeds, such as asparagus fern and Lantana.
- Visitor impacts in high use areas.
- Road widening and maintenance works.
- Trampling by domestic stock.
- Species threatened with extinction via stochastic events due to small population size.
Recovery strategies
Priority actions are the specific, practical things that must be done to recover a threatened species, population or ecological
community. The Office of Environment and Heritage has identified
2 priority actions
to help recover the Marblewood in New South Wales.
Activities to assist this species
- Protect areas of known and potential habitat from clearing and development.
- Control fire in areas of known or potential habitat.
- Ensure walking tracks in tourist areas do not disturb known habitat and stay on established tracks in rainforest areas.
- Protect roadside populations from disturbance.
- Control weeds in areas of known habitat.
- Exclude domestic stock from areas of known habitat.
- Support local Landcare groups and bush regeneration teams.
- Monitor population dynamics and threats at known populations.
- Maintain viable ex-situ seedbank.
