The Woolly Sheoak is a small, erect, densely branched shrub growing to 1.8 m high (Mollemans et al. 1993; Wilson & Johnson 1989).

This species is restricted to a small area in the WA wheatbelt, east of Perth. Two of the four known populations are within Charles Gardner Flora Reserve to the south of Tammin (Briggs & Leigh 1996).

Plants at the type locality, south-west of Tammin, and a nearby population, west-south-west of Tammin, are now extinct. Mollemans et al. (1993) recorded two populations remaining near Tammin and two additional populations, east of Quairading, which were discovered in 1989. The Quairading plants are significantly taller than those in the Tammin area. There are indications that both Tammin populations are in decline because the total number of individuals has decreased from 550+ in 1982, to 280 in 1990 (Mollemans et al.1993).

Population details from Mollemans et al.(1993) are:
1a South of Tammin in reserve, in good condition in 1990, 98 plants
1b South of Tammin in reserve, in good condition in 1990, 182 plants
2a West of Quairading on private land, in good condition in 1990, 59 plants
2b North-west of Quairading on private land, in good condition in 1990, 53 plants

Coates (1990) includes a 1: 50 000 vegetation map showing locations of the remaining populations.

The long fibrous hairs on the cones distinguish this species from A. microstachya and A.grevilleoides (Brown et al. 1998).

This species occurs on low ridges (Wilson & Johnson 1989; Mollemans et al. 1993), on white sand over laterite (Brown et al. 1998). Ironstone is exposed in some areas (Coates 1990). The region experiences dry, warm summers and cool winters and has an average annual rainfall of 342 mm (Weaving 1994).

It grows in tall open heath associated with species such as Acacia campestris, Banksia sphaerocarpa, Hakea aff. falcata, H. strumosa and Leptospermum erubescens. The understorey consists of dense shrubs to 0.5 m high, characterised by Melaleuca holosericea, A. phaeocalyx, Beaufortia interstans, Dryandra speciosa, D.vestita, D. aff. cirsioides, Daviesia rhombifolia, Leptospermum spinescens, Lysinema ciliatum, Leucopogon dielsiana, Petrophile circinata, P. brevifolia, Verticordia brachypoda, V. chrysantha, V. picta and Hemigena viridis (Coates 1990).

This species is dioecious (Mollemans et al. 1993) and flowers Sept.-Nov. (Brown et al. 1998).

Following fire, Allocasuarina fibrosa regenerates from underground lignotubers and also releases seed. The last fire on the reserve south of Tammin was in 1966. Both sub-populations were burnt but have recovered (Mollemans et al. 1993).

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.
