Current status Goodenia integerrima was declared as Rare Flora under the Western Australian Wildlife Conservation Act 1950 in March 1998. It currently meets World Conservation Union (IUCN 2000) Red List Category Endangered (EN) under criterion D as less than 250 mature individuals are known. The main threats are extraction of gypsum, salinity, grazing and inappropriate fire regimes.
Distribution and habitat: Goodenia integerrima is endemic to Western Australia where it is restricted to the Lake King area. Here it grows on elevated gypsum dunes in sandy-clay soils with samphire and other dwarf shrub species such as Pimelea halophila (Brown et al. 1998).
Critical habitat: The critical habitat for Goodenia integerrima is the area of vegetation in which it occurs, remnant vegetation immediately adjacent to the current habitat of the species, corridors of intact vegetation that are linked to the habitat of the species, the local catchment for the groundwater that provides habitat for the species and additional occurrences of appropriate habitat that do not currently contain the species.
Habitat critical to the survival of the species, and important populations: Given that this species is listed as threatened it is considered that all known habitat for wild and translocated populations is habitat critical.
Benefits to other species/ecological communities: There are no threatened ecological communities or other threatened species in the immediate vicinity of Goodenia integerrima. However, recovery actions implemented to improve the quality or security of the habitat of the species, such as weed control and rehabilitation, will benefit the remnant bushland habitat in which it occurs.
International Obligations: 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 Goodenia integerrima 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 any significant adverse social and economic impacts. The species occurs on rises in large salt lakes in a Nature Reserve. It is not known to occur in any areas of Private property.
Evaluation of the Plans 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.
Existing Recovery Actions: The following recovery actions have been or are currently being implemented -
- 1. Many surveys have been undertaken for the species by DCLM's Katanning District staff, DCLM's Science staff and private consultants.
- 2. The Katanning District Threatened Flora Recovery Team (KDTFRT) is overseeing the implementation of this IRP and will include information on progress in its annual report to DCLM's Corporate Executive and funding bodies.
- 3. Staff from DCLM's Katanning District office regularly monitor all known populations.
IRP Objective: The objective of this Interim Recovery Plan is to abate identified threats and maintain and/or enhance in situ populations to ensure the long-term preservation of the taxon in the wild.
Criterion for success: The number of individuals within populations and/or the number of populations have increased by 10% or more.
Criterion for failure: The number of individuals within populations and/or the number of populations have decreased by 10% or more.
|1. Coordinate recovery actions.||6. Undertake rabbit control.|
|2. Reconfirm and monitor populations.||7. Develop and implement a fire management strategy.|
|3. Collect seed and cutting material.||8. Promote awareness.|
|4. Liaise with adjacent leaseholders.||9. Obtain biological and ecological information.|
|5. Conduct further surveys.||10. Review the need for a full RP or updated IRP and prepare if necessary.|
