Synaphea quartzitica was declared as rare flora in July 1998, and was ranked as critically endangered in Western Australia in November 1998. There has since been a perceived decline in level of threat to the species due to reservation of the biggest population and it is now recommended for listing as endangered (EN) under criterion D (World Conservation Union (IUCN) 2000)) due to the low number of plants. Synaphea quartzitica is also listed as endangered under the Commonwealth Environmental Protection and Biodiversity Conservation Act 1999 (EPBC Act). The species is known from four populations, with a total of less than 350 plants, many of which form part of clumps that are assumed to be clones, so it is likely that there are fewer than 200 genetically distinct individuals. The species is threatened by grazing, inappropriate fire regimes and possibly mining.
An interim recovery plan was developed for the species in 1999 (Stack and English 1999). Information accumulated since that plan was completed has been incorporated into this plan and this document now replaces Stack and English (1999).
Population 1 of Synaphea quartzitica occurs within a plant community listed as endangered in Western Australia. This IRP will therefore be implemented in conjunction with the IRP for the community described as 'Heath dominated by one or more of Regelia megacephala, Kunzea praestans and Allocasuarina campestris on ridges and slopes of the chert hills of the Coomberdale Floristic Region' (Hamilton Brown 1999), in which population 1 of Synaphea quartzitica occurs.
The critical habitat for Synaphea quartzitica comprises the area of occupancy of the known populations; similar habitat within 200 metres of known populations; remnant vegetation that links populations and additional nearby occurrences of similar habitat that do not currently contain the species but may have done so in the past and may be suitable for translocations.
Habitat critical to the survival of the species, and important populations
Given that this species is listed as critically endangered it is considered that all known habitat for wild and translocated populations is habitat critical.
Benefits to other species/ecological communities
Population 1 is located within an occurrence of a threatened ecological community, and other declared rare flora (DRF) (Acacia aristulata (DRF), Daviesia dielsii (DRF) also occur in the vicinity of population 1. Acacia aristulata is listed as endangered, and Daviesia dielsii as vulnerable under the EPBC Act. Recovery actions implemented to improve the quality or security of the habitat of Synaphea quartzitica population 1 are likely to improve the status of the threatened ecological community in which this population is located, and populations of other listed species that occur in the same habitat.
This plan is fully consistent with the aims and recommendations of the Convention on Biological Diversity, ratified by Australia in June 1993, and will assist in implementing Australia's responsibilities under that convention. However, as Synaphea quartzitica is not listed under any international agreement, the implementation of other international environmental responsibilities is not affected by this plan.
Role and interests of Indigenous people
There are no known Indigenous communities interested or involved in the management of areas affected by this plan. Therefore no role has been identified for Indigenous communities in the recovery of this species.
Social and economic impacts
The implementation of this recovery plan is unlikely to cause significant adverse social and economic impacts. There are mineral leases over the area that contains population 1 of Synaphea quartzitica, however, an agreement has been negotiated with the mining company with regard to the future management of the area that contains the habitat of the population. Recovery actions refer to continued liaison between stakeholders with regard to this area.
Evaluation of the plan's performance
The Department of Conservation and Land Management, in conjunction with the recovery team will evaluate the performance of this IRP. In addition to annual reporting on progress with listed actions and comparison against the criteria for success and failure, the plan is to be reviewed within five years of its implementation.
Synaphea quartzitica is currently known from a range of approximately 40 linear km in the Moora - Watheroo area. It grows on the slopes of chert hills in open heath with Melaleuca radula and Kunzea species, adjacent to tall shrubland of Allocasuarina campestris. At Population 1, this species occurs with Acacia aristulata (DRF), Daviesia dielsii (DRF), Acacia congesta subsp. cliftoniana (Priority 1), Baeckea sp. Moora (Priority 3) and Regelia megacephala (Priority 4) and is part of the Endangered Heath community on the chert hills of the Coomberdale Floristic Region (Hamilton-Brown 2000).
Existing recovery actions
The following recovery actions have been or are currently being implemented:
- All appropriate people have been made aware of the location and threatened status of the species.
- Declared rare flora markers have been installed at population 2.
- Dashboard stickers and posters describing the significance of declared rare flora markers have been produced and distributed.
- Negotiations to acquire the area on which population 1 occurs as a Nature Reserve are well advanced.
- Staff of the Department's Threatened flora seed centre attempted, largely unsuccessfully, to collect seed in 1997 and again in 1998.
- An information sheet that describes and illustrates the species has been produced.
- Staff from the Department's Moora district regularly monitor populations of the species.
- Detailed investigations have been undertaken into the species' population sizes, reproductive biology and growth rates
- The Moora district threatened flora recovery team is overseeing the implementation of this IRP and will include information on progress in an annual report to the department's corporate executive and funding bodies.
The objective of this interim recovery plan is to abate identified threats and maintain or enhance in situ populations to ensure the long-term preservation of the species in the wild.
Criteria for success
