Scientific name: Kennedia lateritia
Common name: Augusta Kennedia
Conventionally accepted as Kennedia lateritia F.Muell. (CHAH 2010). Previously known as Kennedia macrophylla.
The Augusta Kennedia is described as a "woody twiner", usually growing over low vegetation forming a "creeping cover" of 2 to 4 metres across, but the species can climb up trees to approximately 4 metres (Brown et al. 1998; Rye 1982). The species can be a vigorous climber with long twisted trailing stems (Leigh et al. 1984). Young stems have spreading hairs while older stems are woody. The leaves are made up of three broad glossy leaflets, each up to 7 cm long. The leaf stalks are about 4 cm long and have two leaf-like, very broad stipules at their base which are often joined to one another. Its flowers are 1.5+ cm in length and red with a yellow patch at the base of the largest petal. The individual flowers, each on stalks about 8 mm long, are in scattered groups of three along a common stalk which often is greater then 20 cm in length (Williams et al. 2001).
Confined to coastal dunes on the south coast of Western Australia (Leigh et al. 1984), in the Augusta-Cape Leeuwin area (Brown et al. 1998).
The species' geographical range is less than 5 km (Williams et al. 2001).
The Augusta Kennedia is an established cultivar in the ornamental plant industry in Western Australia and some other states. It is readily grown from seed provided the seeds are scarified before being sown but does not grow well from cuttings. Commercial supplies of seed and nursery plants are obtained from cultivated stocks rather than wild plants of the species (Williams et al. 2001).
Known from four populations near Augusta, with a total population of 100+ plants (Williams et al. 2001):
|Population||No. of Plants||Land Status|
|East of Leeuwin Road||12||Reserve|
|Albany/Deere Street||13||Private Property|
|South west Augusta||15||Private Property|
|South west Augusta||Unknown||Unknown|
The population trend for the species may be in decline. Williams and colleagues (2001) provide a total population figure of 100+ individuals in four populations with low numbers in each population. Rye (1982) identified only three populations with a total population figure of approximately 100 individuals. Of these the largest population close to Augusta, containing 4050 plants, was considered under threat from roadworks as the population is adjacent to a major road and covers an area of less than 0.1 ha (Masters, unpublished report 1978, cited in Leigh et al. 1984).
The Augusta Kennedia occurs close to the coast in black humus-rich sand, often amongst granite outcrops. Typically the vegetation is low coastal heath, but sometimes Peppermints (Agonis flexuosa) or Karris (Eucalyptus diversicolor) are present (Rye 1982). The mean annual rainfall is approximately 1000 mm (Brown et al. 1998).
Flowering has been recorded from September to November (Leigh et al. 1984; Rye 1982). Honeyeaters feeding on the flowers nectar may be the main pollinators. Unopened pods can remain on the plant for over a year, suggesting the pods take a long time to reach maturity. The species produces numerous seeds which are scattered by mechanical means when the pods split open. Plants are probably killed by fire and regenerate from seed. The seedlings are fast growing (Rye 1982).
The main identified threats to the Augusta Kennedia include:
- trampling by tourists
- inappropriate fire regimes
- clearing for development
- weed invasion
Fire can kill plants of this species, but also stimulates germination of seeds. Therefore, it is important that fire regimes are conducted at frequencies that allow new plants a chance to reproduce and add their seed to the soil-stored seed bank.
The threat from weed invasion also increases following fire, and needs to be controlled as part of the fire management strategy (Brown et al. 1998; DEWHA 2007m; Hearn et al. 2004).
Some threat abatement strategies were outlined by Williams and colleagues in their report (Williams et al 2001), however the conservation advice is limited. The strategies for conserving the Augusta Kennedia include:
- Further survey work (to identify patches yet to be discovered).
- Control of problem weeds in localised areas known to contain this species.
- Study into the susceptability of Phytophthora dieback.
- Barriers to exclude tourists from trampling sites.
- Protection from inappropriate fire regimes by identifying patches of this species to local fire authorities.
- Protection from fragmentation and land development by ensuring no or little development occurs within the very limited natural range of the species.
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.
