Acacia pendula is a widespread species common on medium to heavy dark riverine soils in New South Wales, Queensland and isolated subpopulations in South Australia and Victoria in Australia. It is also cultivated in other countries. It is not clear whether this species occurs within the protected areas network and some of the isolated subpopulations of this species are listed locally as Endangered based on an observed decline of 98% in the geographic distribution. However, there is no evidence that the species as a whole has undergone a recent reduction and the species extent of occurrence does not meet the criteria to warrant a threatened category. Therefore, this species is listed as Least Concern. It is recommended that monitoring of habitat and threats is carried out across its range.

Acacia pendula is native to Australia distributed west of the Great Divide from Emerald in central Queensland south through New South Wales to the Victoria border, with isolated occurrences in the Little Desert area in western Victoria, and far eastern as South Australia. It has been also cultivated extensively within Australia and other countries (Orchard and Wilson 2001).

Total population size is not known but a recent survey suggests more than 10 mature individuals from a population in New South Wales (MSBP 2010). Latest collections in 2005.

A tall tree to 12 m high that grows mainly on floodplains in fertile alluvial clay (and red earth soils in the south), sometimes dominant in woodland and open woodland. Associated species vary greatly within each community, but may include black box Eucalyptus largiflorens, bimble box E. populnea, yarran Acacia homalophylla and brigalow A. harpophylla.

The main threats to the species is its occurrence in intensively farmed areas where animals eat the seedlings, allowing little natural regeneration to take place (Moore 2005). Weeping myall occurs mainly within the cropping belt and has consequently been extensively cleared (Boxshall and Jenkyn 2000). The population of A. pendula in the Hunter catchment is listed as an Endangered Population in Part 2 of Schedule 1 of the NSW Threatened Species Conservation Act. This community is threatened by by demographic and environmental stochasticity due to its small population size and potentially vulnerable to clearing since all known sites are in private land (NSW Scientific Committee 2005). The stand at Jerrys Plains is part of the community known as "Weeping Myall - Coobah - Scrub Wilga Shrubland of the Hunter Valley". This is listed under Commonwealth legislation as a Critically Endangered Ecological Community and a 98% reduction in the distribution of this community has been observed.

It is cultivated in many countries and used as a street tree or in many other landscape locations. The tree's hard, close grain, dark colour and heavy weight wood make for an excellent windbreak and has been used to make boomerangs for Aboriginal hunters. The oil from fresh cuts omit a pleasant rich violet fragrance that women placed in their garment drawers. The trees heartwood colour of deep chocolate brown to dark toffee orange has drawn the interest of fine wood working craftsman for the manufacturing of furniture (Arid Zones Trees 2010).

It is not certain how well protected this species within the protected areas network. It is not listed as Threatened under the Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act), however, a population of this species has been listed as Critically Endangered observing a 98% in the reduction of distribution. The seeds for this species have been collected as part of the Millennium Seed Bank project. Seeds are located at: Wakehurst Place, Royal Botanic Gardens, Kew (UK) and Mount Annan Botanic Garden, New South Wales (Australia). It is recommended that monitoring is conducted on the state of the habitat since much of the species is distributed in private land and vulnerable to clearing for agriculture.
