Finding Correlations Among Successful Reintroductions: An Analysis and Review of Current and Past Mistakes

Abstract

In the past half century the world has seen a dramatic decline in species. More and more species are being pushed to brink of extinction. In the past, there have been several methods utilized to mitigate these trends, however with the recent surge of local extinctions, reintroductions have become a growing conservation tool. Despite many disadvantages of developing a reintroduction plan, hundreds have been attempted over the past 40 years, with mixed outcomes. Some conservationists have studied the factors associated with success; however the criteria on which their assessments were based were flawed. I attempted to complete my own assessment of successful programs using detailed program information along with life history traits of focal species. My results illustrate the many obstacles faced by reintroduction biologists. Based on the limitations faced throughout this study, I conclude that conservationists must take a step back and address the many issues with current reintroduction protocols prior to attempting any further assessments. My recommended solutions to some of these issues include defining universal criteria for a reintroduction program to be considered successful; monitoring, logging, and disseminating standardized data; and collaborating with captive facilities that have the ability to offer additional support.
