Threatened bryoid habitats

Habitat alteration and degradation for development and agriculture are the principle threats to bryoids.

Bryoids are defined as bryophytes (mosses, liverworts, and hornworts) and lichens (foliose or fruticose; not crustose). Non-vascular (lower) plants lack true conducting tissues, leaves and roots. Since they lack elaborate conducting tissues they are relatively small. The gametophytes are the dominant phase and the sporophytes are dependent upon them. Non-vascular plants require water for fertilization so they must grow in moist or seasonally moist habitats.
