Calliergon cordifolium is a pleurocarpous moss, meaning its stems grow horizontally along the substrate. Its vibrant green hue and delicate, heart-shaped leaves are its most distinctive features. The leaves are cordate (heart-shaped) and concave, giving the moss a unique and visually appealing appearance.

Global Distribution and Habitat

This moss species is widely distributed across the Northern Hemisphere, thriving in various habitats such as

wetlands, bogs, fens, and moist woodlands. It is particularly abundant in regions with cool, temperate climates and prefers moist, acidic environments rich in organic matter.

Ecological Roles and Adaptations

Calliergon cordifolium plays a vital role in its ecosystem, acting as a sponge and regulating water flow. Its dense mats help retain moisture, creating a microhabitat for other organisms to thrive. Additionally, this moss species is known for its ability to tolerate a wide range of environmental conditions, making it a resilient and adaptable plant.

Case Studies/Examples

One notable example of the ecological importance of Calliergon cordifolium can be found in the Sphagnum bogs of Northern Europe. These unique ecosystems are home to a diverse array of plant and animal species, and Calliergon cordifolium plays a crucial role in maintaining the delicate balance of these fragile environments.
