Description

The golden fern, scientifically known as Acrostichum aureum, in the Pteridaceae family, also known as the “marsh fern,” is a large fern that can grow up to 3 meters tall. It has thick, leathery fronds (fern leaves) that range in color from green to golden brown when mature. The upper part of the frond bears sori (structures that contain spores) that are typical of ferns.

Habitat

It is found primarily in wetlands, including marshes, mangroves, and riverbanks, as well as in ponds. It is particularly adapted to saline soils and can tolerate high salt levels, making it an important component of mangrove ecosystems.

Importance and uses

This plant plays a crucial role in stabilizing soils in mangrove ecosystems, helping to prevent coastal erosion. It also provides a habitat for numerous wildlife species, including insects and small aquatic animals. In Guadeloupe, this plant contributes to the richness of mangrove ecosystems, where it helps maintain ecological balance and protect coastlines from erosion.

In addition to its ecological role, Acrostichum aureum is used locally for medicinal and artisanal purposes. Some cultures use it to treat various ailments or as a weaving material.
