The primary function of quarantine regulations in biodiversity conservation is to prevent the introduction and spread of invasive species and pathogens that can threaten native ecosystems. These regulations help safeguard biodiversity by controlling the movement of plants, animals, and microorganisms across borders. By limiting the risk of biological invasions, quarantines protect local species and habitats, maintaining ecological balance. Effective quarantine measures are vital for preserving ecosystems and preventing biodiversity loss, especially in vulnerable regions already facing environmental pressures and climate change impacts.
