A new study highlights the dangers of releasing rescued animals back into the wild, revealing that for some species, this process can be more harmful than helpful. Researchers from Anglia Ruskin University, Plumploris e.V., and the University of Western Australia conducted a study on Bengal slow lorises (Nycticebus bengalensis) released in Bangladesh, finding that many did not survive due to challenges such as predation, habitat loss, and competition for resources. The findings suggest that even animals deemed ready for release may lack the skills or adaptability needed to thrive in their natural environments.
The study, published in *Global Ecology and Conservation*, tracked 28 Bengal slow lorises over two years after their release into a protected forest area. Despite efforts to prepare the animals for reintroduction, including habitat enrichment and health monitoring, researchers observed high mortality rates. Factors such as unfamiliar predators, limited food availability, and the stress of reintegration contributed to the poor outcomes. This raises important questions about the effectiveness of captive-release programs and the assumptions behind them.
The research underscores the complexities of reintroducing animals into the wild, particularly in ecosystems that have changed significantly since their capture. Habitat degradation and human activity often make it difficult for released animals to find suitable
