Post-release survival and welfare outcomes for rehabilitated wildlife vary significantly by species and condition, with monitoring studies revealing important information about rehabilitation effectiveness and guiding best practice.
Release success monitoring reveals that rehabilitation welfare outcomes depend heavily on the condition of animals at release and the quality of release site selection. Animals released prematurely or in poor condition face welfare harm from inability to compete, find food, and avoid predators. Post-release monitoring enables rehabilitation organizations to evaluate their practices and identify which animals benefit most from rehabilitation effort. Species with high post-release survival in good condition justify rehabilitation investment; species with low survival rates require honest evaluation of whether the welfare cost of rehabilitation is justified by release outcomes.
