AWMS Position on
Translocation for Conservation
Background
This position statement seeks to promote a structured and considered approach
to the movement and release of living organisms for conservation objectives. It
acknowledges the Commonwealth's Endangered Species Advisory Committee's draft
Policy for Translocations of Vertebrate Animals in Australia and the 1987 IUCN
statement on translocation of living organisms. However, in developing this
statement, AWMS has recognised the need to make a series of modifications to
accommodate the principles of adaptive management.
Translocation is defined here as the movement of an organism from one place
with free release in another and refers collectively to: (1) introduction, (2)
re-introduction and (3) re-stocking.
- Introduction refers to non-endemic species and their movement into an area
where they did not formerly exist. Such introductions are made for a variety
of reasons: hunting, fishing, economic development, and as biological
control agents. In the past introduction of many exotic species has been
disastrous and it is important to recognise that translocation of endemic
species may also lead to similar undesirable outcomes. Therefore caution
should be exhibited when translocating endemic as well as exotic species.
- Re-introduction refers to the release of a species of plant or animal into
an area where it was indigenous before it was exterminated by a natural
event or by humans. The latter could result from human persecution,
over-harvesting or from habitat modification, or deliberate or accidental
introduction of pests.
- Re-stocking refers to the release of a plant or animal species into an
area where it is already present in order to increase its population size.
It is recognised that translocation is a valuable conservation tool, both in
terms of restoration of plant and animal communities and assessing the extent of
ecosystem dysfunction. For example, successful translocation programs include
those for the Woylie (Bettongia penicillata) and the Chatham Island Black Robin
(Petroica traversi). Nevertheless there are potential risks with translocation
conservation strategies. For example, disease transmission and impact on other
endemic populations may result.
THE AUSTRALASIAN WILDLIFE MANAGEMENT SOCIETY ACKNOWLEDGES THAT:
- Before any translocation activity occurs, the need for the program should
be assessed, the objectives of the proposed program clearly identified, the
desired outcomes stated with clear assessment criteria, and monitoring
techniques specified (this may include the need for a pilot program and long
term monitoring). The program should be supported by locals and other
stakeholders, and funding and other resources must be identified for the
duration of the planned program.
- The long term aim should be to seek self sustaining populations under
natural conditions with minimal human intervention.
- There should be a net conservation gain to the translocated species and
other native species should not become threatened by the process.
- A species should not be translocated into an area until the current
threats have been controlled to an appropriate or acceptable level, unless
the program is part of a project designed to identify these threats.
- Taxa involved in a re-introduction program must be as close as possible to
those occurring in the area previously, and should preferably be the same
taxa.
- Introduction of non-endemic species should be condoned only if clear
benefits to natural communities can be foreseen, and it can be predicted
reliably that there are no disadvantages. For example, translocation of
threatened species to offshore islands.
- Full documentation of the entire program should occur to allow
transmission of information about both successful and unsuccessful
translocation.
- An introduction program should be monitored and countermeasures be in
place to restrict, control or eradicate the translocated species if it
becomes a threat to other native species.
- As far as possible translocated individuals should not contain diseases or
parasites which could jeopardise other native species.
- Natural resource management agencies develop policies and procedures for
translocation.
