Pteridophytes are of minor economic significance to humankind as compared to other groups of plants, especially angiosperms. However, many of them are horticulturally desirable and used for decorations and ornamental purposes and some also as medicines and food. In the present study, the diversity, distribution and conservation perspectives of pteridophytic flora in homegarden ecosystems in the Polgolla Grama Niladhari Division (PGND), Kandy district, Sri Lanka, were investigated. All conceivable habitats of pteridophytes within homegardens and suburb areas in the PGND were visited frequently over a period of one year and representative samples were collected and preserved as herbarium specimens. The species collected were identified using the “Revised Handbook to the Flora of Ceylon” (Vol. XV and XVI) and verified with the specimens deposited at the Herbarium, National Botanic Gardens, Peradeniya, Sri Lanka. The study found 32 species of pteridophytes belonging to 12 families in homegardens and suburbs of three villages in the study area namely Megodagama, Egodagama and Gangewattegama. Although the importance and the conservation measures of pteridophytes have not been understood by the residents, many pteridophytes have been commonly grown as ornamental, crop and medicinal plants in their homegardens. This preliminary survey highlights the species richness of pteridophytes and the importance of conservation of existing species in PGND.
