Forest's Wattle is a stiff, spiky, erect shrub and grows from 0.4 to 1 m high (Brown et al. 1998; Orchard & Wilson 2001).

The species grows in two localities - near Dandaragan and near Jurien Bay, north of Perth in south-western WA (Hopper et al. 1990; Brown et al. 1998; Orchard & Wilson 2001), over a range of about 80 km (Brown et al. 1998). Many populations are conserved in Lesueur National Park (Patrick & Brown (2001).

The species is closely allied to A. huegelii, which has a more southerly distribution and a different phyllode shape (Patrick & Brown 2001).

The species inhabits gullies and slopes of lateritic hills (Hopper et al. 1990; Brown et al. 1998; Paczkowska & Chapman 2000), often growing in rocky or lateritic clay loams (Brown et al. 1998; Paczkowska & Chapman 2000; Orchard & Wilson 2001), or gravelly soils over sandstone (Paczkowska & Chapman 2000). The vegetation is heath or low woodland (Brown et al. 1998; Orchard & Wilson 2001) of Eucalyptus wandoo and E. calophylla. Scrub includes Hakea lissocarpha and Grevillea, Acacia, Isopogon, Calothamnus and Melaleuca species (Brown et al. 1998: Patrick & Brown 2001).

The globular pale yellow flower heads (Brown et al. 1998; Paczkowska & Chapman 2000; Orchard & Wilson 2001) are borne Oct. to Dec. (Hopper et al. 1990; Brown et al. 1998).

Plants are killed by fire. Regeneration is via seed (Patrick & Brown 2001).

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.
