Overview

Palustriella commutata, commonly known as curled hookmoss, is a plant that also goes by the binomial names Cratoneuron commutatum, Cratoneuron falcatum, Hypnum commutatum, and Hypnum falcatum.

Curled Hook-moss faces significant threats from habitat degradation and loss of its specialized wetland environments. Climate change and altered hydrology from human activities are reducing the availability of suitable calcareous spring and seepage habitats. Water pollution and eutrophication further compromise the water quality conditions this species requires for survival.

Threat summary

Habitat

Calcareous springs, seepages, and wet rock faces in mountainous and hilly regions, typically growing on limestone or other calcium-rich substrates. Also found along stream banks and in other permanently moist, mineral-rich environments with consistent water flow.
