Respondents were asked about the Mitchell’s satyr, a federally endangered subspecies of butterfly found in less than two-dozen peatlands in Michigan and northern Indiana; forest replanting for timber production using genotypes or species from farther south; and zooxanthellae, the algal symbionts of coral that appear to be temperature sensitive (Sotka and Thacker, 2005). Percentage of respondents saying (a) managed relocation in each case would be somewhat or very justifiable, (b) managed relocation would be somewhat or very effective at achieving its goal, (c) they are somewhat or very supportive of managed relocation, and (d) the ecological impacts of managed relocation would be somewhat or very beneficial compared to its detrimental impacts, N = 2,239 published environmental scientists. The questions in (a–c) included four response categories ranging from “very” to “not at all”; (d) included five response categories ranging from “very beneficial” to “very detrimental,” with a middle alternative of “equally beneficial and detrimental” and a sixth alternative of “no detectable impact.” The results show that scientific opinion on justifiability, potential effectiveness, potential benefits, and support for managed relocation varies depending upon the species and context in question.
