Interim recovery plan no 136

2. Recovery objective and criteria

Objectives

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.

Criteria for success: The number of individuals within populations and/or the number of populations have increased by 10% or more. Criteria for failure: The number of individuals within populations and/or the number of populations have decreased by 10% or more.

3. Recovery actions

Existing recovery actions

Numerous surveys for new populations of Goodenia integerrima have been undertaken by DCLM Katanning District staff, DCLM Science staff and private consultants.

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.

Staff from DCLM's Katanning District office regularly monitor all populations.

Future recovery actions

Where populations occur on lands other than those managed by DCLM, permission has been or will be sought from the appropriate land managers prior to recovery actions being undertaken.

1. Coordination

The KDTFRT is coordinating the implementation of recovery actions for Goodenia integerrima and will include information on progress in the annual report to DCLM's Corporate Executive and funding bodies.

Action: Coordinate recovery actions
Responsibility: DCLM (Katanning District) through the KDTFRT Estimated Cost: $600 per year.

2. Monitoring

Known populations of Goodenia integerrima will be monitored and plant counts undertaken during the species October, November flowering period. Monitoring will include weed invasion, habitat degradation, salinity levels and population stability (expansion or decline), pollinator activity, seed production, recruitment, and longevity. Soil salinity and pH readings will be taken during winter and summer.

Action: Monitor populations
Responsibility: DCLM (Katanning District) through the KDTFRT
Estimated Cost: $2,700 per year.

3. Germplasm collections

Preservation of germplasm is essential to guard against extinction if wild populations are lost. Seed and cutting collections can also be used to propagate plants for translocations and to establish a living collection at the Botanic Gardens and Parks Authority (BGPA).

Action: Collect seed and cutting material
Responsibility: DCLM (Katanning District, TFSC) and BGPA, through the KDTFRT
Estimated Cost: $3,400 per year.

4. Liaison

Lease holders have yet to be notified about the presence of Goodenia integerrima adjacent to the land that is currently being mined for gypsum. Staff from DCLM's Katanning District will liaise with them to ensure that populations are not damaged or destroyed accidentally.

Action: Liaise with adjacent leaseholders
Responsibility: DCLM (Katanning District) through the KDTFRT
Estimated Cost: $900 per year.

5. Surveys

Further surveys, supervised by DCLM staff and with assistance of local volunteers and wildflower society members, will be conducted during the flowering period (Late October to November) of Goodenia integerrima.

Action: Conduct further surveys
Responsibility: DCLM (Katanning District) through the KDTFRT
Estimated Cost: $2,200 per year.

6. Rabbit control

Rabbits have the potential to cause minor damage to the species at all populations. Where identified as a need during monitoring DCLM will initiate control using the most appropriate method in cooperation with land users.

Action: Undertake rabbit control
Responsibility: DCLM (Katanning District) through the KDTFRT
Estimated Cost: $900 per year.

7. Fire management strategy

The response of Goodenia integerrima to fire is not known. However, frequent fire may prevent the accumulation of sufficient soil stored seed to allow regeneration of the populations. Fire should therefore be prevented from occurring in this area at least in the short term. A fire management strategy will be developed to determine fire control measures and fire frequency.

Action: Develop and implement a fire management strategy
Responsibility: DCLM (Katanning District) through the KDTFRT
Estimated Cost: $2,700 in first year and $1,000 in subsequent years.

8. Community awareness

The importance of biodiversity conservation and the need for the long-term protection of Goodenia integerrima in the wild will be promoted to the public through the local print, electronic media and poster displays. An information sheet, which includes a description of the plant, its habitat type, threats, management actions and photos will be produced. Formal links with local naturalist groups and interested individuals will also be encouraged.

Action: Promote awareness
Responsibility: DCLM (Katanning District, Corporate Relations) through the KDTFRT
Estimated Cost: $1,600 in first year and $900 in subsequent years.

9. Biology and ecology

Better knowledge of the biology and ecology of Goodenia integerrima will provide a scientific basis for management of the wild populations. An understanding of the following is necessary for effective management:

  1. The pollination biology of Goodenia integerrima
  2. The soil seed bank dynamics, seed life and the effect of disturbance, competition, rainfall and grazing on germination and seedling survival.
  3. Reproductive strategies, phenology and seasonal growth.
  4. Population genetic structures, levels of genetic diversity and minimum viable population size.
  5. The impact of salinity on Goodenia integerrima and its habitat.

Action: Obtain biological and ecological information
Responsibility: DCLM (Science Division, Katanning District) through the KDTFRT
Estimated Cost: $19,200 per year for five years

10. Review Interim Recovery Plan

At the end of the fourth year of the five-year term of this Interim Recovery Plan, the need for a full Recovery Plan, or a review of this IRP, will be assessed and a plan prepared if necessary.

Action: Review the need for a Full Recovery Plan or updated IRP
Responsibility: DCLM (WATSCU, Katanning District) through the KDTFRT
Estimated Cost: $20,800 once in the final year if required.
