4.49 In such cases, a range of measures may be used by the wildlife control operator to mitigate or minimize risks, including the temporary removal of animals from the site, with the aim of returning animals back to their habitats at the completion of risk-associated works.

4.50 Important criteria for return of animals to the original development site include:

(a) Sufficient habitat is, or will be retained on site to support the animal population, taking into account factors such as: viability of prey species populations; availability of nesting sites or cavities; availability of clean water; and availability of sufficient food resources.
(b) Habitat corridors retained are of suitable size, topography and vegetation cover to provide effective routes for normal ecological processes such as immigration, emigration, recruitment and dispersal.
(c) Habitat blocks and corridors are of sufficient size to maintain ecological integrity and effectiveness, taking into account likely edge effects.
(d) Long-term risk factors to individual and population survival associated with the development have been (or will be) adequately managed or mitigated. For example: domestic animal control, motor vehicle/road impacts, swimming pool risk.

4.51 The temporary removal of native animals destined for return back to the site of origin, is conditional upon the availability of appropriate long-term holding facilities and resources, and the suitability of the species and individuals for long-term holding.

4.52 In some instances, it may be appropriate to construct temporary holding yards or enclosures on site during operational works, which are removed on completion of riskassociated works.

Translocation of animals to suitable habitat adjacent to development site

4.53 If development of a site occurs adjacent to a large area of similar habitat, with little retention of habitat on site, native animals are most appropriately translocated into adjacent areas. Criteria for use of adjacent habitat are as for 4.64 a-d, but include:

(a) Translocation of animals into adjacent habitat should only occur if the likelihood of significant impacts on resident animals in the recipient habitat is considered to be low. (i.e. Recipient habitat is not considered to be at maximum carrying capacity for that species.)
(b) Recipient habitat is of sufficient size to allow for dispersal of individuals from the point of release, with minimal likelihood of mortality.

For example: raccoons may disperse long distances from the point of release, particularly in already occupied habitat and should not be released into small habitat fragments bounded by busy roads or other hazards.
