Abstract

Traditional cultural and religious beliefs and practices play a crucial role in the conservation of the environment and biodiversity in the form of the sacred groves. The present study was carried out to explore the plant resources, their biological spectrum, leaf size spectra, the conservation status of a sacred grove, locally known as Narampur Barapir Astana (NBA) in West Midnapore district of West Bengal in India. Floristic list of the study revealed that the vegetation of NBA was diverse and composed of 277 species belonging to 238 genera distributed over 77 families under 36 orders according to APG IV classification. The dominant order and family in terms of species richness were Lamiales 27 (9.75%) and Fabaceae 32 (11.55%) respectively. The biological spectrum shows the study area was classified as “thero-chamae-cryptophytic” type of phytoclimate. As regards the leaf size spectra, mesophyll 56 (20.22%) was found to be high. The study area being a sacred grove is fairly undisturbed. For the long-term conservation of germplasm of the grove some recommendations are suggested.

Abstract

The open coastlines of the world are dominated by sand dunes and salt marshes. They are the primary areas for human recreation and provide a wide range of frequently overlooked ecosystem services. Their intrinsic ecological significance lies in having unique biological assemblies and supporting a range of ecological processes, such as water filtration and nutrient cycling. In addition, in the coastal zone, these areas link marine and terrestrial systems. The objective of this paper is to check the psammophytic species diversity, conservation status and threat; and also prepare a biological spectrum m in the Costal East Midnapore (CEM) district's sand dune and salt marsh areas. A part of floristic inventories in the CEM, various field trips in different season were carried out, quadrate method is done to examine the ecological impact and richness. Specimens were collected, prepared voucher specimen and enlisted according APG IV classification system to prepare biological spectrum. CEM vegetation was diverse and composed of 162 species of 132 genera distributed among 52 families of 28 orders according to APG IV classification, of which 37 species were exotics. Fabales (19.14%) and Fabaceae (19.14%) were the dominant order and family. Biological spectrum shows the study area was classified as “thero-chamaephytic” type of phytoclimate. Mesophyll (24.07%) and lanceolate as well as oblong (19.14%) were found to be high in the leaf size spectrum and lamina. The area of study was highly ecotonal potential and fairly undisturbed. This study is useful in comparing and contrasting the adjacent natural vegetation along the gradients of the environment; and recommends effective long-term conservation and better management of the coastal area.
