Abstract:
Pteridophytes are regarded as one of the pioneer plant species which emerged on Earth. After the
invasion of bryophytes, these plants emerged and stood dominant for centuries on earth 's crust.
While the emergence of other dominant plant groups had subsided these ones, and is now
prevailing as only one of the groups on Earth. After the fifth mass extinction, today mother
nature is facing threats of climate change with a greater extent of biodiversity loss, which is the
major outcome of anthropogenic activities. India is one among the megadiverse countries, of
which Western ghats and Sri Lanks are regarded as one of the hotspots of the total 34 global
hotspots. Despite the lush complexity of plants, this plant group is facing the threat of
vulnerability and extinction. In this scenario a floristic assessment is the need of the hour in order
to determine the present status of plant distribution. Floristic analysis, whether small or large, all
have the same stand for contribution to the metadata of science. Present work is based on the
Taxonomic studies of Pteridophytes of Chingoli Panchayat of Alappuzha.
