Conservation translocations (reintroductions, reinforcements, ecological replacements, and assisted colonization) have played a vital and necessary role in conserving endangered species and ecosystems. Yet concerns over potential unintended ecological consequences frequently hinder the progress of translocation activities. We reviewed the history of U.S. translocations to ask: how often were intended benefits the result versus harmful unintended consequences? We found that translocations played a key role in recovery for 30% (14 of 47) of U.S. delisted taxa. Translocations have been performed, are planned, or are part of continuing recovery actions for 70% (1,112 of 1,580) of listed threatened and endangered taxa. Of the 1,014 total taxa we found with recorded conservation translocations spanning 125 years, we found only one restricted instance that caused a loss of biodiversity. All other reports of negative consequences were caused by translocations performed for economic and cultural interests in the absence of conservation-based governance. Examples included fish stocking for sport and biological control programs for agricultural pests. We included biological control programs in this analysis because they can be and often are used as conservation tools, to directly benefit ecosystems.

In June 2020, Revive & Restore hosted the Intended Consequences Workshop to explore how the field of conservation can realize the benefits of genetic interventions and address concerns about unintended consequences of these actions. A group of 57 participants from eight countries representing government, academia, and conservation practice discussed how implementation of genetic interventions designed to achieve conservation objectives can be optimized to both address concerns about risk and achieve the intended consequences. Genetic interventions are efforts designed to manipulate the genetic composition of a conservation target at a species or population level. The planning and implementation of genetic interventions in conservation raises questions about how key constituencies are involved in the process and how risks and benefits are characterized and evaluated. Governance frameworks are critical to structuring dialogue and decision‐making among interested parties around the development of these conservation efforts in a manner that addresses risks, benefits, and equity considerations. In this article, we explore related issues of policy and governance, key constituencies, and risk as raised during discussions at a 2020 workshop on “Intended Consequences” of conservation interventions. We examine how different constituencies characterize risks of genetic interventions within particular sociocultural contexts. We then revisit the characterization and framing of risks to suggest ways that the perspectives of different constituencies can be visualized in a manner to inform resulting policy decisions.
