National recovery plan for Tuggeranong Lignum (Muehlenbeckia tuggeranong)
A Recovery Plan under the Environment Protection and Biodiversity Conservation Act 1999 (Cwlth), based on an Action Plan (Action Plan No. 24) prepared for the species under the Nature Conservation Act 1980 (ACT).
5. Conservation and Management Actions
- Specific Management Actions
- Performance Criteria
- Evaluation of Performance
- As it is unlikely that the species exists anywhere else in the ACT, surveys beyond its immediate location are not economically justified. However, awareness of the species by field workers and others is important for potentially locating other sites. Environment ACT (Wildlife Research and Monitoring) will monitor the existing population annually.
- Environment ACT (Wildlife Research and Monitoring) will advise field workers, interested naturalists and conservation groups of the presence of the species to increase the potential that any other existing populations are identified.
- Environment ACT (Wildlife Research and Monitoring) will liaise with the NSW National Parks and Wildlife Service to encourage surveys of potential habitat outside the ACT.
Due to the nature and small size of the site containing the species, management actions will be directed towards maintaining the existing conditions and ensuring that adjacent activities do not adversely affect the site. . The management actions being undertaken are unlikely to have any adverse impact on other native species or ecological communities.
- Research into the species will be encouraged. (Ongoing)
- Facilities, such as walking tracks, will not be developed near the sites, with the aim of discouraging visitor access to the area. (Ongoing)
- A 'low profile' will be maintained for the sites where the species is located, with no signs or fencing being erected. (Ongoing)
- Statements of conservation objectives and intended management actions for the species will be placed in relevant management plans and strategies. (Ongoing)
- Once plants have fully recovered from the January 2003 bushfires, Environment ACT will undertake controlled pollination among all possible combinations of male and female plants as a first step to increasing population size. Cuttings will also be taken for regeneration purposes. (Year three)
- The population of Muehlenbeckia tuggeranong is monitored annually and the population is maintained. (Annual)
- Existing habitat conditions are maintained at the site by avoidance of potential threats (especially construction of visitor facilities). (Annual/ongoing)
- Statements of conservation objectives and intended management actions for the species are placed in relevant management plans and strategies. (Ongoing)
- Controlled pollination of plants has been undertaken and results evaluated (dependent upon recovery of plants from January 2003 bushfires). (Year 3)
Environment ACT has primary responsibility for implementation of this Recovery Plan and will review progress of the Plan after three years, using the above performance criteria. The review will be reported to the ACT Flora and Fauna Committee providing the opportunity to assess progress and establish revised directions and priorities for future conservation action.
The main group of seven plants is located in the Pine Island Recreation Area of the Murrumbidgee River Corridor (MRC) (Public Land (Special Purpose Reserve) under the Territory Plan). The eighth plant is in the Bullen Range Nature Reserve of the MRC. Management responsibility rests with Environment ACT (ACT Parks and Conservation Service, Murrumbidgee River Corridor District).
Conservation efforts will be focussed on protecting the existing specimens in accordance with the specific management objective in the Murrumbidgee River Corridor Management Plan (p. 21) to protect the habitats of rare and threatened plant and animal species (ACT Government 1998).
The response of the species to fire was not recorded until 2001 when a fire burnt one plant and this recovered from basal shoots. A fire of very high severity burnt the area in January 2003. A subsequent survey showed the recovery of all plants from basal shoots (Carey et al. 2003).
