Calcium fern, scientifically known as Polypodium dryopteris var. calcareum, is a unique species of fern that thrives in calcium-rich environments. This variant of the common water fern is distinguished by its ability to absorb and utilize calcium from its surroundings, making it a rare indicator of specific soil conditions. Found primarily in limestone areas and rocky habitats, it plays a vital role in maintaining ecological balance in these regions. Its delicate fronds and intricate structure make it a subject of interest for botanists and nature enthusiasts alike. Despite its beauty, the Calcium fern faces threats from habitat destruction and environmental changes.
