AI Summary

Researchers analyzed 24 years of small‑mammal tracking data from New Zealand’s public conservation lands and found that aerial 1080 poison drops, while sharply cutting rat and stoat populations, often allow the predators—particularly ship rats—to rebound to higher numbers within a few years. The timing of these rebounds differs across regions, indicating that local factors influence how quickly predator numbers recover after treatment. This variability suggests that management strategies may need to be tailored to regional rebound patterns.
