    ABSTRACT

    The study explored the Economic Importance of Pteridophytes in various sectors such as agriculture, medicine, industry, and environmental management. Pteridophytes, including ferns, have been recognized for their role in ecological restoration, soil conservation, and air purification. Their ability to thrive in a range of environments, from wetlands to rocky terrains, makes them a valuable resource for maintaining ecosystem balance. Furthermore, pteridophytes have been extensively utilized in traditional medicine for their therapeutic properties, with several species being used to treat ailments such as respiratory diseases, digestive disorders, and skin conditions.

    Data from recent studies indicate that ferns can significantly improve soil fertility, enhance water retention in arid regions, and promote biodiversity by supporting a variety of plant and animal species. Despite their vast economic potential, pteridophytes face numerous challenges, including overexploitation, habitat loss, and the impacts of climate change. Therefore, it is essential to adopt strategies for their conservation, such as habitat restoration, sustainable harvesting practices, and public awareness campaigns about their ecological and economic value.

    The findings from this study underscore the need for continued research into the economic utilization of pteridophytes, particularly in the areas of sustainable agriculture, bioactive compound extraction, and ecological restoration. With appropriate conservation measures, pteridophytes can continue to offer significant benefits to both local communities and global industries. The research also accents the importance of integrating these plants into broader environmental management frameworks to ensure their preservation for future generations. Based on the findings of this research, it was recommended that policies aimed at regulating the trade and harvesting of pteridophytes should be developed to ensure that their economic benefits are harnessed without causing harm to their populations or ecosystems.



    Economic Importance of Pteridophytes


    1.0 Introduction

    1.1 Background of Study

    In ancient civilizations, pteridophytes held medicinal and cultural importance. In traditional Chinese medicine, ferns were used to treat various ailments including skin diseases, fevers, and parasitic infections (Wu, Raven, & Hong, 2006). Indigenous communities in Africa and South America also used certain species for food and healing purposes. For instance, the young fronds of Diplazium esculentum have been historically consumed in parts of Asia and the Pacific as a vegetable with nutritional and therapeutic benefits (Bunyapraphatsara et al., 2001). Pteridophytes, commonly known as ferns and their allies, represent an ancient group of vascular plants that reproduce through spores rather than seeds. These plants are distinct in their possession of true roots, stems, and leaves, and their ability to thrive in a variety of terrestrial and aquatic environments. As the first vascular plants to evolve, pteridophytes play a significant role in understanding plant evolution and development (Gifford & Foster, 1989).

    Traditionally, pteridophytes have been regarded for their ecological contributions, such as maintaining biodiversity, stabilizing soil, and participating in nutrient cycling. However, their economic importance has become increasingly recognized in recent years. Several species are cultivated as ornamental plants due to their aesthetic foliage and adaptability to indoor and outdoor conditions. In regions such as Southeast Asia and Africa, edible ferns are a common part of local diets, contributing to food security and cultural practices (Bunyapraphatsara et al., 2001).

    Sasidharan et al. (2011) articulated that, the increasing interest in pteridophytes in pharmacological research has further highlighted their significance as sources of bioactive compounds with antimicrobial, anti-inflammatory, and antioxidant properties (Sasidharan et al., 2011). Pteridophytes are vascular cryptogams that include ferns and their allies, such as horsetails and club mosses. These plants are characterized by the presence of vascular tissues (xylem and phloem) but do not produce seeds or flowers; instead, they reproduce through spores (Raven, Evert, & Eichhorn, 2005).

    Pteridophytes occupy an important position in the plant kingdom as the first group of vascular plants to have evolved, bridging the gap between non-vascular bryophytes and seed-producing plants such as gymnosperms and angiosperms. Beyond their biological and ecological relevance, pteridophytes also hold substantial economic importance. They serve various functions ranging from ornamental use, food and medicine, to soil conservation and industrial applications. For instance, species such as Azolla are widely used as biofertilizers due to their symbiotic relationship with nitrogen-fixing cyanobacteria (Anabaena azollae), contributing to sustainable agriculture (Wagner, 1997). Therefore, this research study aims to examine the economic importance of pteridophytes, considering their roles in agriculture, medicine, industry, and environmental conservation.


    1.2 Statement of Problems

    Investigation revealed that pteridophytes are rich sources of bioactive compounds, which is useful in developing treatments for infections and chronic diseases (Sasidharan et al., 2011). However, the majority of these species remain under-researched, leaving their pharmacological potential largely untapped. This knowledge gap limits the integration of pteridophytes into modern medicine and pharmaceutical innovation.

    Additionally, the problem is not merely the underutilization of these plants, but also the declining interest in documenting indigenous knowledge and traditional uses of pteridophytes, which is vital for cultural preservation and sustainable resource management. Without intentional efforts to explore, educate, and promote the economic relevance of pteridophytes, their contributions will continue to be underappreciated and their survival threatened.

    Furthermore, the ornamental and cultural value of many fern species is diminishing due to habitat loss, urbanization, and the absence of conservation efforts. Even though these plants thrive in diverse environments and are valuable for indoor and outdoor landscaping, they are rarely included in mainstream horticultural and ecological restoration programs (Page, 2002). It is against the backdrop that this study seeks to address these problems by accenting the economic importance of pteridophytes, promoting a better understanding of their roles in medicine, agriculture, industry, and environmental management.
