National recovery plan for the Isis Tamarind (Alectryon ramiflorus) 2003-2007

Recovery plan

2. Recovery objectives and criteria

Primary objective

The primary objective of the Recovery Plan is to downlist A. ramiflorus from endangered to vulnerable within 15 years of the plan's implementation.

Specific recovery objectives

  1. To improve the conservation of in situ populations.
  2. To raise awareness of this species among land managers and the general public, and incorporate into land management decisions the importance of rare and threatened species.
  3. To conduct further species-specific surveys to ascertain whether any additional populations can be found.
  4. To promote the re-establishment of native vineforest including viable populations of A. ramiflorus based on sound knowledge of the species' ecology.
  5. To propagate more individuals of this species, ideally from as many parent plants as possible.
  6. To preserve the genetic resources of the species ex situ.
  7. To implement a research and monitoring program, including population monitoring and research into plant propagation and cultivation, comparative morphological and genetic variability, and the ecological requirements of the species.

Performance criteria

The success of the recovery plan will be judged against the following performance criteria:

  1. The conservation of in situ populations is improved though habitat protection and site management:
    • Nature refuges and road closure negotiated with the appropriate authority.
    • Management of sites negotiated with landowners or trustees.
    • Relocated part of the cattle proof fence around the Cordalba site.
    • All known sites maintained by controlling weeds and introduced animals, protecting the sites from fire and promoting the expansion of patches.
    • There is no net loss of A. ramiflorus populations.
    • Ex situ grown plants are planted into known sites.
  2. Land managers and the public are well informed about A. ramiflorus and the Isis Scrub and have access to information that promotes their long-term survival through dissemination of information and organisation of community activities.
  3. Further species-specific surveys are conducted. All significant vineforest remnants in the region are surveyed for the presence/absence of A. ramiflorus and known populations are protected from identified threats.
  4. Re-establishment of at least one patch of native vineforest including a viable population of A. ramiflorus.
  5. Further individuals of this species are propagated and distributed to re-establishment sites, known sites and to each of the major regional botanic gardens in south-east Queensland with plantings sufficient to preserve the genetic variability of the species. The location and management of plants are documented and readily available to interested parties.
  6. Ex situ genetic resources preserved through:
    • The lodgement of plant material from the 17 adult plants into the Australian Plant DNA Bank.
    • The lodgement of seeds into the Australian Tree Seed Centre or a local seed bank, to ensure maximum longevity of the viability of seeds.
    • The planting of plants representing the genetic range into at least two botanical gardens.
    • Research into viability and storage of seed undertaken through the Australian Tree Seed Centre.
  7. A research program implemented and preliminary research findings obtained, including:
    • Successful techniques in plant propagation and cultivation.
    • Analysis of the comparative morphological and genetic variability of A. ramiflorus.
    • Ecological requirements of the species.
    • Determination of the health, and the factors affecting the health, of existing populations, individuals and plantings through monitoring.

Evaluation of the recovery plan

The Alectryon ramiflorus recovery team will monitor the progress of the recovery plan and regularly assess the implementation of recovery actions.

The recovery plan will be independently reviewed in 2007. A revision of the plan will be written at the end of the five-year period, or earlier, if new information warrants major changes.
