Total Population Size Minimum Population Size: Maximum Population Size: Habitat and Ecology This large shrub grows on sandy soils over laterite or limestone in plains, hills and winter-wet flats of Western Australia. It grows in woodlands, shrublands or heath.

Threats This species is susceptible to Phytophthora cinnamomi, the jarrah dieback pathogen (Groves et al. 2009). This is a serious threat to the forest areas which caused the death of thousands of hectares of forest in this area (Boden and Given 1995). It is recommended that D. physodes populations and the effects of jarrah dieback pathogen on these populations are monitored in the near future. Much of the original vegetation of south-west Western Australia has been cleared for urban development and agriculture, and much of the remaining land is privately owned.

Most of these protected areas are from the north-west part of the species range, therefore it is recommended that further protected areas are identified. This species is not listed as Threatened under the Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act) and it has been assessed under the CALM Conservation Code for Western Australian Flora as Not Threatened (Smith 2010). Its seeds have been collected for the Millennium Seed Bank Project, with seed collections stored at: Wakehurst Place, Royal Botanic Gardens, Kew (UK) and Dept. of Conservation & Land Management-Threatened Flora Seed Centre (CALM-TFSC) (Australia).

IUCN Red Listing Red List Assessment:(using 2001 IUCN system) Least Concern (LC)

Red List Criteria: Date Last Seen (only for EX, EW or Possibly EX species): Is the species Possibly Extinct?  Possibly Extinct Candidate?  Rationale for the Red List Assessment D. physodes is listed as Least Concern in view of its wide distribution in Western Australia within its natural range, the fact that it is known to occur in protected areas and that its seeds have been banked for ex situ conservation. Since the area where this species occurs was cleared for urban development and agriculture it is recommended that the remaining fragmented habitat is surveyed in the near future to asses the state of the populations and that new protected areas are identified. It is also recommended that the impact of P.cinnamomi pathogen on D. physodes populations is continued to be closely monitored.
