    Connecting buyers and sellers of Biodiversity Units

    Gaia is the world's first online platform bringing together buyers and sellers of Biodiversity Units. It makes it easy for land managers to connect with surveyors, and for developers to secure the units they need for BNG compliant developments. And most importantly everyone is working together to halt the decline in nature.

    BNG, made simple with Gaia

    What are BNG units?

    Biodiversity net gain units have dominated developer and land owner discussions lately. Our clear guide cuts through the confusion and explains:

    When you can draw on off site units
    How the units are calculated
    The potential value of the units

    What are BNG credits?

    BNG credits are very different from BNG units and are a last resort. Our guide explains:

    The government's role in BNG credits
    How long they might be needed
    When it might be appropriate to secure credits

    Habitat types for BNG

    There are three overarching habitat types for BNG. Gaia builds them in so you can identify at a glance the most appropriate projects for you. Our guide explains:

    The three habitat types
    Examples within the habitats
    The difference between area, hedgerow and watercourse habitats

    The biodiversity metric

    The metric for calculating BNG units has been developed by Natural England. Our guide cuts through the complexity and covers:

    The five distinctiveness categories
    Habitat condition assessments
    The strategic significance of sites
    Location and habitat content
