Reintroduction ecology is the scientific study and practice of returning plant species to habitats where they have been extirpated or have declined, with the goal of restoring self-sustaining wild populations. This field is critical to plant conservation biology, as it combines knowledge of seed ecology, plant-soil interactions, population genetics, and habitat restoration to maximize the survival and establishment of transplanted individuals. Understanding the ecological requirements and limiting factors for successful reintroduction helps inform strategies for preserving plant biodiversity in the face of habitat loss and climate change.
Zoo-raised hellbenders (large aquatic salamanders) have far less diverse gut bacteria than wild ones, but switching them to a wild diet helps restore that microbial balance—and their gut communities continue shifting toward wild-type after release into natural habitats.
Introducing a wild diet in zoo settings modulated the gut microbiome, with change primarily driven by bacterial species turnover rather than abundance shifts.

Both bacterial and fungal gut communities restructured after release into natural habitat, trending toward wild-type composition—suggesting microbiome recovery is possible post-reintroduction.
