Understanding translocation success
Work out the likely success of your species translocation, when you follow best practices and factor in genetic variability.

Will your planned translocation succeed?

Translocation is one of a range of tools you can use when carrying out a species recovery or ecological restoration project. However, translocation success is highly variable depending on the target species and release site, with many translocations (c. 40–60%) failing. Therefore, careful planning is essential, particularly when selecting an appropriate release site.

Successful translocations have high initial survival rates, rapid population growth and ultimately produce large, genetically diverse populations that persist well into the future.

The following factors are critical for successful translocations:

  • the number of individuals you transfer (founders)
  • the type, quality and size of habitat at the release site
  • the extent of predator control at the release site

There is ongoing scientific debate around how translocation success should be defined and measured, but all translocations go through several distinct phases. The phases are: transfer, survival, evidence of reproduction, population growth, and viable population. Consideration of these phases may help you to assess the success of your translocation.
