“…Thévenin () pointed out that an advantage of evaluating survival to PBA was that it connected an individual parameter to a demographic process influencing population establishment. We agree with Chauvenet's () point that such short‐term success indicators should eventually be evaluated in the context of long‐term population persistence.…”

Through a reintroduction case study on the critically endangered Vancouver Island marmot Marmota vancouverensis, we introduced a 'stepping-stone' approach which utilizes the transition of released individuals among populations to maximize demographic growth potential (Lloyd et al., 2019). We greatly appreciate and hereby reflect on the thoughtful commentaries by Chauvenet (2019), Hayward (2019) and Th evenin (2019) to propose three key topics for future exploration.Determine if stepping-stone approach may work for any species While the stepping-stone technique showed promise with a colonial, social mammal within a meta-population structure, Chauvenet (2019) wondered what parameters might explain these positive effects to better determine the applicability for other species. We agree such information would be valuable to further marmot recovery, and we also anticipate that the explanatory mechanisms may differ in type or magnitude among species. We encourage an adaptive management approach to iteratively address sources of uncertainty for new trials. As such, ongoing learning would optimize management decisions without precluding the opportunity to test this technique for other species.The stepping-stone approach is attempting to use highly suitable release areas to allow individuals to learn or adapt before transfer to additional sites that are demographically important but have conditions which make establishment difficult. Developing key survival behaviors such as foraging, finding shelter, and avoiding predators are critical for all species regardless of taxa or life history.Hayward (2019) highlighted the challenge of recapturing released individuals at the stepping-stone site before final release at the subsequent location. We agree that potential recapture rates should be predicted and monitored due to potential variation arising through behavior, release site conditions, and tracking technology. In our study design (Lloyd et al., 2019), we addressed this issue, quantified recapture rates, and reflected upon the results to address potential applicability for other species. Specific methods and metrics of stepping-stone trials should be adapted for each species and context.Overall, we believe the stepping-stone approach may be feasible across taxa if three core conditions are present: (1) at least one wild population exists and the program goals include additional population(s); (2) multiple release site populations are available that differ in establishment suitability; (3) individuals can be recaptured at initial release sites and transferred with minimal stress to subsequent release populations.Determine if stepping-stone approach may work for any source, type, or stage of conservation translocationThe stepping-stone approach likely has primary applicability for improving the survival of na€ ıve captive-bred individuals in the wild, but it could also be useful for wild-to-wild translocations. Post-release effects afflict nearly all translocations (Armstrong et al., 2017) regardless of source. Even wildtran...
