Metapopulation and translocation research for the species conservation programme natterjack toad (EVINBO)

Project Details


The Agency for Nature and Forests (ANB) wants to implement actions 6.5 and 6.6 from the Species Protection Programme (SBP) by means of a genetic survey of the Flemish (meta) populations. This will result in a translocation plan for the natterjack toad in Flanders, so that every proposed translocation, such as relocation or reintroduction, is scientifically justified.

Previously implemented translocations are evaluated based on genetic results and practical experiences in order to develop a translocation methodology and to learn lessons for future initiatives.

Through genetic research of populations, we can determine the current state and estimate the genetic structure between several populations.

This allows us to:

1) to test whether certain populations have a reduced genetic diversity compared to reference populations (populations in a favourable conservation status)
2) examine whether we can speak of a genetic bottleneck
3) to determine to what extent genetic exchange exists between neighbouring populations
4) To determine the potential for sustainable survival by estimating the effective size of populations and comparing it with genetic criteria for the sustainable conservation of populations in the short and long term.

Thus, this genetic research should provide clarity on potential measures, in particular with regard to translocation, to maintain, enhance and guarantee the long-term viability of each Flemish (meta)population.
