ECOLOGICAL SIGNIFICANCE OF PLANT LIFE FORMS OF AN URBAN GREEN SPACE OF PURULIA REGION, WEST BENGAL, INDIARimi Roy, Manideepa Bhattacharya, Barsha Baral and Deblina Das Modak
Purulia is one of the prominent arid regions of West Bengal, India. The present work was conducted to determine the lifeforms of the existing plants and their ecological significance at the Jagannath Kishore College campus which is an urban green space located in Purulia city, West Bengal. Work also aimed to determine the biological spectrum of the study site that reflects the phytoclimate and adaptations to arid conditions of the region. On comparison with Raunkiaerâs normal spectrum it was revealed that there was much higher abundance of therophytes (23.86%) than the normal spectrum thus, indicating warm and arid climatic conditions. However, phanerophytes (46.59%) and cryptophytes (5.68%) were almost equal to the normal spectrum, depicting more or less stable vegetation. From the present study it was observed that the study site is phanero-therophytic in nature.
