Ecological relationships

Eaten by

  • Hawfinch
    HawfinchCoccothraustes coccothraustes

    The Hawfinch's beak generates approximately 50-70 kg of crushing force, sufficient to split Hornbeam nutlets that no other European passerine can open. This morphological specialisation is one of the most striking examples of beak-seed coevolution in European birds.

  • Marsh Tit
    Marsh TitPoecile palustris

    Feeds on hornbeam nutlets in mixed beech-hornbeam stands.

Mycorrhizal partner of

  • Summer Truffle
    Summer TruffleTuber aestivum

    Ectomycorrhizal; Hornbeam is a principal host in calcareous European woodlands. Fills the significant gap of Hornbeam having no previous fungal partners in the database.

  • Hornbeam Milkcap
    Hornbeam MilkcapLactarius circellatus

    Near-obligate ectomycorrhizal partner of Hornbeam; one of the most host-specific Lactarius species in Europe.
