Just Preservation

In 2018, we published our ethic of public trusteeship, non-anthropocentric, multispecies justice that presents a method to give voice to future generations and to nonhumans when decisions are made to allocate or preserve nature. Start here with the original article Treves, A., Santiago-Ávila, F., Lynn, W.S. (equal co-authors) 2018. Just Preservation. Biological Conservation 229: 134-141.

The newest discussion of Just Preservation played out in 2021 in in the journal Animal Sentience, which included commentaries by several dozen colleagues and our replies to each: F.J. Santiago-Ávila, A. Treves (equal co-authors), W.S. Lynn, Just preservation, trusteeship and multispecies justice. Animal Sentience 393. This continues our work on trusteeship, legal standing for nonhumans, and future generations, and equitable consideration of nonhumans as members of our moral community.

Chapron, G. and A. Treves 2016a and b, 2017a and b. We first showed that Michigan and Wisconsin wolf population growth slowed whenever the government liberalized wolf-killing and the slow-down was proportional to the length of time that culling was liberalized, regardless of how many wolves were killed. Then starting a lively debate, Pepin et al. tried to counter our hypothesis but did not succeed in our opinion. That debate improved our model which strengthened its findings, also in the pages of Proceedings of the Royal Society B Strengthening our findings. and

a 2017 rebuttal. Then Stien and Olson and his colleagues tried again.

Those critiques only made our evidence stronger. Olson et al. in particular weakened their own position. Furthermore, independent findings for Mexican wolves presented by David Parsons in 2014 corroborate the idea that relaxing protections slows population growth more than expected.
