Dillwynia juniperina LC Taxonomic Authority: Lodd. Global Assessment Regional Assessment Region: Global Endemic to region Synonyms Common Names PRICKLY PARROT PEA English (Primary) Upper Level Taxonomy Kingdom: PLANTAE Phylum: TRACHEOPHYTA Class: MAGNOLIOPSIDA Order: FABALES Family: LEGUMINOSAE Lower Level Taxonomy Rank: Infra- rank name: Plant Hybrid Subpopulation: Authority: Dillwynia sieberi Steud. and Dillwynia juniperina Lodd. were both confused under D. juniperina. General Information Distribution Dillwynia juniperina is endemic to Australia, distributed in the states of New South Wales and Victoria, also in the Australian Capital Territory. It occurs only in a few sites in south New South Wales (in Culcairn, Trunkey and Bowan Park) and in the Northen Tablelands populations are in fragmented woodlands, often along road easements and often in a very degraded state with weed invasions (Gross 2001). Range Size Elevation Biogeographic Realm Area of Occupancy: Upper limit: 1200 Afrotropical Extent of Occurrence: Lower limit: Antarctic Map Status: Depth Australasian Upper limit: Neotropical Lower limit: Oceanian Depth Zones Palearctic Shallow photic Bathyl Hadal Indomalayan Photic Abyssal Nearctic Population Total population size and dynamics are not known, but it has been recently collected in 2004. Total Population Size Minimum Population Size: Maximum Population Size: Habitat and Ecology A shrub that grows in dry sclerophyll forest and woodlands usually on poor skeletal, sandy or gravelly soils. Its flowers obligately require pollination by bees (Gross 2001). System Movement pattern Crop Wild Relative Terrestrial Freshwater Nomadic Congregatory/Dispersive Is the species a wild relative of a crop? Marine Migratory Altitudinally migrant Growth From Definition Shrub - large Perennial shrub (>1m), also termed a Phanerophyte (>1m) Threats There are no major threats known to this species. However, the habitat where this species is distributed was extensively cleared for industrial and urban development, furthermore human-caused fires might threaten some populations in this fragmented habitat. Past Present Future 1 Habitat Loss/Degradation (human induced) 1.4 Infrastructure development 1.4.1 Industry 1.4.2 Human settlement 1.7 Fires Conservation Measures Some populations of this species occur with protected areas, most notably in Warby Range State Part (Victoria) and Morton National Park in New South Wales. However, more research is needed to verify the range of this species, since this species was confused with D. sieberi. This species is not listed as Threatened in the Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act). It is also recommended that its seeds are banked for ex situ conservation.

Possibly Extinct Candidate? Rationale for the Red List Assessment D. juniperina is listed as Least Concern in view of its wide distribution through south-eastern Australia within its natural range and the fact that it is known to occur in protected areas. The species has not been classified as Threatened by the EPBC Act, however it is recommended that this species is surveyed to understand population dynamics and size to determine the full extent of its range, and that its seeds are banked as an ex situ conservation measure.
