Ecological
followed previous reintroductions of 262 juvenile Astrochelys radiata in the sacred forest Sirempo have revealed that
individuals released directly without acclimatization left the site at 98%. The
local habitat fulfilled all the conditions necessary for the development and
survival of the species, and this site was
recognized as distribution range of the species, but with a population whose
abundance to decline over the last ten years. The research project “Development of Technical
Reintroduction and Population Monitoring of Radiated Tortoises (Astrochelys radiata) in Southern
Madagascar: Ampotaka” in a pre-identified natural environment conducive to
their growth will preserve their viability, and predetermine site fidelity through an acclimation
period before release. Realizing monitoring contributes to restoring
self-sustaining populations in the wild, in cooperation and harmony with the
manners and customs, and in trying to follow as much as possible the
rigorous procedures already recognized by IUCN to prevent the transmission of
diseases to wild populations and/or to prevent genetic mixing of different
subpopulations in order not to endanger wild populations.
