The overall goal of Recovery is to minimise the probability of extinction of the twelve threatened Caladenia taxa in the wild and to increase the probability of each population of each taxon becoming self-sustaining in the long term.
Within the life span of this Recovery Plan (2000-2004 inclusive), the specific objectives of recovery for the twelve threatened Caladenia taxa are to:
- Ensure that all existing populations are adequately protected;
- Increase the numbers of plants in the wild;
- Establish a genetically representative ex-situ collection of endangered taxa in cultivation;
- Increase the number of populations in the wild; and
- Raise public awareness and foster community involvement.
The criteria for assessing the achievement of these objectives are the:
- Determination or update of conservation status for all taxa for inclusion on state and national threatened species lists;
- Establishment of a protected area network within the range of threatened Caladenia taxa incorporating a range of public land and private land protection mechanisms and management agreements involving a range of public land management agencies, statutory authorities and private landholders;
- A measurable decrease in the number and magnitude of identified threats to populations;
- An increase in the abundance of vulnerable taxa to twice current numbers;
- A measurable increase in the reproductive output and recruitment of endangered Caladenia taxa and an increase in abundance to at least 5x current numbers;
- Identification of key components of the biology and ecology of threatened Caladenia taxa;
- Development of successful propagation techniques and successful establishment of an ex situ collection of endangered taxa consisting of 100 plants of each taxon to be held in cultivation;
- Establishment of at least one additional population of each endangered taxon in a secure reserve in the wild; and
- Increased community involvement in pivotal aspects of criteria above.
