Abstract
Present study deals with species diversity parameters for herbaceous natural vegetation around three sites of Moradabad city. The Importance Value Index of species was estimated seasonally for each site. Total 77 species of herbaceous plants have been observed from these three sites which belong to 32 families. All vegetations show more or less striking differences for every few feet. Species diversity index, richness (D1), Margalef index (D2), Menhinick index (D3), evenness (D4) and beta diversity at each site were highest in rainy season. The β diversity was highest at Kanth Road Site and much lower at Rampur Road and Delhi road Site in rainy season whereas, Concentration of dominance was highest at Rampur road in winter season. The herbaceous vegetation showed a mosaic pattern which was more pronounced in rainy months than in summer and winter months. Species dominance altered with sites and seasons with increasing tendency of species like Ranunculus scleretus, Cynodon dactylon, Achyranthus aspara, Parthenium hysterophorus, Saccharum spontaneum, Solanum xanthocarpum, Euphorbia hirta, Alocasia indica and Trianthema portulacastrum. Similarity coefficient revealed that dominant species composition tended to exhibit distinctness with respect to site and season. Human population and industrial discharge also influenced the species composition and diversity in these habitats.
