Floristic composition, biological spectrum and plant diversity of burnt and unburnt grazing lands of Dewghat forest, Koraon range (U.P.).

摘要

Studies on floristic composition, species diversity and life forms were made in burnt (BP) and unburnt (UBP) grazing lands in Dewghat forest of Koraon range, Allahabad region of Uttar Pradesh, India. Approximately 18, 4, 12 and 77 species belonged to grass, sedge, legume and non-legume forbs, respectively. The biological spectrum for BP and UBP indicated the preponderance of therophytes followed by chamaephytes where the former was 5% more on BP than UBP, thus exposed thero-chamaephytic to phytoclimate. Species diversity ranged between 3.98 and 5.19 and there was no significant difference between BP and UBP, an indication that fire did not affect much the species diversity during post burnt period..
