11.0 Recovery performance criteria

Recovery performance criteria are listed below.

  • Criterion 1: current conservation status is determined;
  • Criterion 2: any identified extant populations are protected and population numbers increased;
  • Criterion 3: protection of potential habitat is increased through community awareness and involvement;
  • Criterion 4: agents which contributed to the decline of the species are determined and actions taken to control them; and
  • Criterion 5: the taxonomic status of both species is determined.

12.0 Recovery actions

12.1 Survey and research

  1. Survey of previously inadequately surveyed potential habitat on the southern Monaro and eastern edge of the South Eastern Highlands for extant populations of the Yellow-spotted Bell Frog by suitably qualified and experienced people. (Objectives 1 and 2; Performance criterion 1)
  2. Development and implementation of a community awareness program, based on the production and distribution of an information pamphlet, to encourage and assist identification of any extant populations of the Yellow-spotted Bell Frog and the Peppered Tree Frog on the New England Tableland. Programs to be developed specifically for each species, and any program should be co-ordinated with local interest groups. (Objectives 1, 4 and 5; Performance criterion 3)
  3. Development and implementation of a community awareness program based on encouraging and assisting the identification of any extant populations of the Yellow-spotted Bell Frog in the southern part of the South Eastern Highlands. Program to be based on the production and distribution of an information pamphlet, and should be coordinated with local interest groups. (Objectives 1, 4 and 5; Performance criterion 3)
  4. Continuation of the community awareness program for the Yellow-spotted Bell Frog in the northern part of the South Eastern Highlands. Program should be coordinated with local interest groups. (Objectives 1, 4 and 5; Performance criterion 3)
  5. Cooperation and coordination of recovery programs between NPWS and Environment ACT regarding the status and reasons for decline of the Yellow-spotted Bell Frog on the South Eastern Highlands. (Objective 6; Performance criterion 4)
  6. Verification of historic records of the Yellow-spotted Bell Frog and the Peppered Tree Frog to document historic range and habitat requirements of the species. (Objectives 1 and 2; Performance criterion 1)
  7. Research to determine the causative agents in the decline of the Yellow-spotted Bell Frog and the Peppered Tree Frog to be supported. This may form part of a broader program to assess threats to a wide range of amphibians. Research into the possible role that increased levels of ultraviolet radiation and Batraochytrium dendrobatidis (chytrid fungus) have played in the decline of both the Yellow-spotted Bell Frog and the Peppered Tree Frog is considered a high priority.(Objective 6; Performance criterion 4)
  8. Genetic studies using museum collection specimens to resolve the taxonomic status and nomenclature of the southern and northern populations of the Yellow-spotted Bell Frog and that of the Peppered Tree Frog will be supported. (Objectives 3 and 7; Performance criterion 5)
  9. Resolution of the identification of possible Peppered Tree Frog populations recently recorded through the examination of type specimens from these populations and type specimens of Litoria pearsoniana (Pearson's Tree Frog). (Objectives 3 and 7; Performance criterion 5)
  10. The NPWS will recommend that field researchers working in areas of potential habitat for the Yellow-spotted Bell Frog or Peppered Tree Frog abide by the hygiene protocol for the control of disease in frogs developed by the NPWS (NPWS 2001). (Objectives 5; Performance criterion 3)

Outcome

Assessment of conservation status and taxonomic status of the Yellow-spotted Bell Frog and the Peppered Tree Frog, identification of any extant populations and determination of agents which have contributed to the species' decline.

12.2 Protection of potential habitat

  1. State and Local Government authorities and community groups with responsibilities relevant to the protection of the Yellow-spotted Bell Frog and the Peppered Tree Frog and their habitat will be made aware and kept informed by the NPWS of the species' conservation requirements and the location of known populations and potential habitat. Relevant authorities are identified in Table 3. (Objectives 4 and 5; Performance criteria 2 and 3)
  2. Design of community involvement programs (actions 2 - 4 above) will incorporate measures to encourage protection and appropriate management of potential habitat for the species. (Objective 4; Performance criterion 3)
  3. Environmental Impact Assessment guidelines will be prepared by NPWS, to assist those required to prepare or review assessment of likely impacts on the Yellow-spotted Bell Frog or the Peppered Tree Frog in relation to proposed developments or activities. (Objectives 2, 4 and 5; Performance criterion 3)

Outcome

Increased protection of habitat of the Yellow-spotted Bell Frog and the Peppered Tree Frog.

12.3 Legislative status

  1. Review of the legislative status of the Yellow-spotted Bell Frog and the Peppered Tree Frog in the TSC Act and the EPBC Act. Should an upgrade in status be required, NPWS will make a nomination submission to the NSW Scientific Committee and/or responsible commonwealth authorities. (Objective 1; Performance criterion 1)

Outcome

Legislative status of both species reflects current conservation status.

12.4 Protection of any extant populations identified

  1. Development of an ex situ establishment protocol to be implemented in the event that an extant population of either the Yellow-spotted Bell Frog or Peppered Tree Frog is found and it is determined that establishment of a captive population is necessary. This protocol is to include required approvals so that appropriate procedures are in place should decision be made for urgent establishment of an ex situ captive population. (Objective 5; Performance criterion 2)
  2. Confirmation by field investigation of reasonable reports from the public of extant populations of the Yellow-spotted Bell Frog and the Peppered Tree Frog in NSW. (Objectives 2, 3 and 5; Performance criterion 1)
  3. If reports of extant populations of either species are confirmed, an assessment of the site's habitat attributes and a survey for the species in areas with similar habitat in the vicinity will be undertaken by suitably qualified and experienced people, to identify the extent of the population. Specimens are not to be vouchered without the specific approval of the NPWS. (Objectives 1, 2 and 5; Performance criteria 1, 2 and 3)
  4. If any populations of the Yellow-spotted Bell Frog are confirmed in NSW declaration of critical habitat under the TSC Act will be considered in consultation with landowners. Critical habitat will be protected as a high priority (same for the Peppered Tree Frog if TSC Act status changed to endangered). (Objective 5; Performance criteria 2 and 3)
  5. Protection and management of confirmed extant populations of the Yellow-spotted Bell Frog and the Peppered Tree Frog in NSW through Voluntary Conservation Agreements under the National Parks and Wildlife Act 1974 (NPW Act) or Joint Management Agreements under the TSC Act to be investigated as a high priority. (Objective 5; Performance criteria 2 and 3)
  6. If extant populations of either species are found, appropriate management strategies are to be devised and implemented as a high priority in consultation with landowner or manager. This is to include consideration of the establishment of ex situ populations. (Objective 5; Performance criteria 2 and 3)
  7. Research relevant to the management of sites with extant populations to be supported. (Objective 5; Performance criterion 3)

Outcome

The protection of any extant populations that are identified in the future.

13.0 Implementation

Table 1 allocates responsibility for the implementation of recovery actions specified in this plan to relevant government agencies for a period of five years from the time this recovery plan is adopted. Table 2 identifies costs associated with each recovery action.

14.0 Preparation details

This document was prepared by the NSW National Parks and Wildlife Service. Authors: Michael Murphy, Michael Mahony, Ross Knowles and Pamela Gray. Background information and assistance was provided by Doug Binns, Will Osborne, Robyn Molsher and Katrina McKay.

15.0 Review date

This Recovery Plan will be reviewed within five years of the date of publication. The plan includes a review of the conservation status of the Yellow-spotted Bell Frog and the Peppered Tree Frog at the end of the five-year life of the plan. Should extant populations be identified during the life of this recovery plan, the plan will be revised appropriately to achieve the recovery of the species. If no extant populations have been identified over the life of the plan, the species will be proposed for listing as presumed extinct in NSW under Schedule 1 Part 4 of the TSC Act.
