Pratique des translocations végétales conservatoires en France : dimensions réglementaires, organisationnelles et économiques
Archive ouverte
International audience. While the literature in ecology on conservative plant translocations has developed significantlyin recent years, very few studies on the practical conditions for their implementation, includingthe economic aspects, have been conducted. However, these non-strictly biological factors areimportant to consider because they can influence the feasibility and efficiency of translocationoperations. Through a series of interviews with national botanical conservatories (CBN), one ofthe major actors in plant translocations, as well as a few complementary actors, we review theregulatory, organizational and economic dimensions of the practice of conservative planttranslocations in France. In particular, we collected the economic costs of the involvement of sixCBN in 34 translocation operations, associated with three stages that we feel it is interesting todifferentiate in a translocation: preparation, the translocation itself, and the post-translocationphase. It is the two phases upstream and downstream of the translocation operation per se thatinvolve the largest share of costs. We also showed that the motivation underlying a translocation operation, that is within or outside the mitigation hierarchy of development projects, did not significantly influence its cost, which suggests an equivalent implication of the actors interviewed (at least economically) in the two cases identified. The analysis of the economic costs of plant translocations, limited to the involvement of the CBN in this article, should now be completed for the other actors involved. The detailed network of the actors involved in translocations as well as the description of the different stages they encounter and that we propose in this article constitute an essential starting point.
