Abstract

Among the numerous microorganisms in the soil, earthworms play an important role in the formation and maintenance of soil structure and fertility by altering the physical, chemical and biological properties. A study was conducted in Wayanad district during 2017 to 2018 to collect and identify the earthworm species present in three agro climatic regions of Wayanad. A total of 30 samples were collected from Wetland, upland and an evergreen forest. A total of 15 earth worm species were identified and among this two species were new to Wayanad, the Dravida thomasi and Amynthas corticis.
