Executive summary Introduction This is a regionally based multi-species recovery plan for twenty-one nationally listed and two state listed threatened plant species found on Eyre Peninsula, South Australia. Table 1 lists the species addressed in this plan. The recovery plan is prepared within the requirements of the Commonwealth Environment Protection and Biodiversity Conservation Act 1999 and guidelines produced by Environment Australia (2002). The plan’s strategic, regional approach to threatened flora recovery will provide direction to managers who are planning for and funding the sustainable management of Eyre Peninsula’s natural resources (see Sections 4 and 29-31 in particular). Individual species sections in the plan (Sections 6-28) will be useful for plant enthusiasts wishing to pursue recovery of individual species or groups of species (e.g. orchids or wattles) that are specific to their region or area of interest. The individual species sections present information such as biology and ecology, known threats, and recovery actions for each of the 23 species addressed in the plan. Goals and objectives Two recovery goals form the basis of this plan: Goal 1 Recover threatened plant species critical habitat on Eyre Peninsula. Goal 2 Recover threatened plant species populations on Eyre Peninsula. These are 30 year goals, as they are realistically achievable only over a long-term time frame (i.e. by 2037). The threatened flora species addressed within this plan (Table 1) are prioritised based on the literature, field observations, formal studies, previous actions and known threats. The recovery of these species, and their critical habitat, will be achieved through the completion of Objectives, Actions and Performance Criteria (Section 4 and Appendix D). Priority Focus Work Areas are identified in Figure 30.1. Recovery of threatened flora species is defined by five objectives: Objective 1 Obtain baseline information, including critical and potential habitat, for each threatened flora species. Objective 2 Increase understanding, appreciation and involvement in threatened flora recovery efforts. Objective 3 Manage immediate threats and improve threatened flora critical habitat. Objective 4 Conduct research critical to management by addressing knowledge deficiencies in threatened flora biology and ecology (including threat identification). Objective 5 Monitor threatened flora populations and evaluate the success of recovery actions. Actions within the recovery plan are relevant for 5 years, at which point the plan will require review. During review, progress towards the goals should be assessed and actions may subsequently need to be modified. Success will be determined by whether species are either down-listed or stabilised, according to IUCN criteria (IUCN 2001). It is likely that within 5 years some threatened flora species will be successfully down-listed (see targets in Table 1); however, the ability to down-list species is influenced by the species’ priority category (Table 29.1) and the corresponding level of allocated resources.

To fund the entire recovery plan, a financial investment of approximately $ 300 000 per year for 5 years will start meeting the conservation needs of all threatened flora taxa and cricital habitat identified within this plan. Wider benefits Implementation of this plan contributes to holistic natural resource management goals, including habitat protection and management, linking fragmented habitats, strategic threat abatement, and community engagement in regional biodiversity and conservation issues. Anticipated broader ecological benefits of the plan include: • maintenance of habitat integrity that facilitates ecosystem adaptation to climate change • protection of water dependent ecosystems, such as wetlands and riparian areas, within threatened flora species critical habitat • an improved understanding of threatened flora and insect/pollination processes • an improved understanding of soil biota function in threatened plant habitats.
