Many of us enjoy the familiar home environment, but what if we have to move to a strange place to survive?

A study from the University of Otago investigated Maintenance Shift Strategies for the two New Zealand Taonga Race– Tuatara and takahē – Address the issue of novelty in such an environment.

Was announced in Conservation science frontierThis study focused on the risks and benefits of transfers and created a strategic framework for transfer strategies.

Lead author James Hunter-Ayad, Ph.D. Animal science candidates say it’s increasingly difficult to protect Natural world Faced with human-induced environmental changes.

“Conservation activists have to make tough decisions to find the best way to conserve our natural resources and to get the best opportunity to make the right choice, green in the decision-making process. It is essential to consider the evidence.

“Through this research, we have developed a framework to help apply and address this evidence-based approach to conservation. Difficult decision On how to relocate seeds for conservation purposes, ”he says.

Researchers have developed two translocation strategies to deal with animal novelty and the resulting uncertainty.

Conservative strategies, known as “conservative” and “extrapolated”, which operate on the spectrum avoid and eliminate new conditions as much as possible, while extrapolated strategies are more experimental and novel. Gain a better understanding of species ecology by allowing exposure to conditions and monitoring of results.

“Like everyone strategy It presents specific risks and opportunities and can be applied to different scenarios. Extrapolation strategies face new and emerging threats that require less traditional translocations, such as the recovery of species that allow experimental management or assisted colonization. Suitable for seeds, ”says Hunter Ayad.

The researchers worked with the Department of Nature Conservation to apply the framework to two species with a long history of translocation management, tuatara and takahē.

Using these species as case studies, we learned how each strategy could be put into practice. Thus, these two iconic native species of New Zealand are the descendants of strategic advances that can help protect many species around the world.

Hunter-Ayad says that the relocation of species should be carefully considered and targeted for specific situations.

“The unifying principles can be applied by applying a consistent framework for working on these decisions, which should help ensure that the best results are obtained. “

He describes this development as a “pioneer” in maintenance management.

“Advances in the theory and practice of conserving nature in Aotearoa, New Zealand, could lead to better management of endangered species around the world.

“We expect something conservative and extrapolated. Frame Conservation practices are moving away from traditional conservative approaches, known as ‘fortress’ conservation, towards a goal of increasing ambition and scope to include ecosystem services, ecosystem restoration and rewilding as primary goals. The more you do, the more relevant it will be. “
