Mangrove ferns, such as Nephrolepis exaltata (Boston fern) and Acrostichum aureum (mangrove fern), play important roles in both the mangrove ecosystem and the environmental purification process.
Environmental Purification:
Mangrove ferns are adapted to grow in high-salinity environments, such as mangrove swamps, and have the ability to purify water in several ways:
Absorption of nutrients and pollutants: The roots of these ferns, which are partially submerged in water, are capable of absorbing excess nutrients and pollutants present in the water, helping to purify it. This is crucial for maintaining the water quality of mangrove swamps and coastal areas.
Sediment filtration: The leaves and roots of ferns act as natural filters, trapping sediments and suspended particles in the water. This contributes to the water's clarity and prevents sediment accumulation in the mangrove bed, maintaining ecological balance.
Absorption of heavy metals: Some ferns can absorb heavy metals present in the water, such as mercury and cadmium. This process of phytoremediation helps reduce the concentration of these pollutants, which can be toxic to local fauna and ecosystems.
Desalienation and its symbolic role:
In relation to the concept of desalienation, which refers to the process of reconnecting with nature and distancing from a fragmented and distorted view of the natural world, mangrove ferns play an important symbolic role. They are plants that represent the resilience of nature in the face of adversity. By surviving in extreme environments and purifying water, ferns remind us of the importance of preserving natural ecosystems and the role plants play in maintaining environmental balance.
Additionally, ferns have symbolic value in the restoration and rehabilitation of degraded ecosystems. By promoting the regeneration of native vegetation and restoring the health of mangroves, they contribute to the desalienation of degraded ecosystems, helping to restore balance and environmental health, as well as increasing people's connection with nature.
These natural processes of purification and regeneration are essential for both environmental and human well-being, and mangrove ferns play a crucial role in this context.
