Biological spectrum and other structural functional attributes of the vegetation of Kumaun Himalaya

摘要: Spectra on life form, leaf size, persistence, flowering season, and shade tolerance of trees in different vegetation types occurring within the north-western catchment river Gola Kumaun Himalaya are presented. The flora Quercus leucotrichophora, lanuginosa floribunda forests is phanerophytic, that Pinus roxburghii mixed therophytic. grassland characterized by largest percentage hemicryptophytes. whole area, biological spectrum for entire as therohemigeophytic. Among various altitudinal zones, tropical has a preponderance phanerophytes, temperate alpine observations size indicate with exception forest, all types, species microphylls greater number. In this region, expression evergreen, although tree considerable content deciduous elements. forests, period most vernal. On basis relative density, greatest proportions adult intolerant, while leucotrichophora maximum intermediate tolerance. With exhibit dominance which tolerant at seedling stage. forest except have 74.5 to 100% potentiality vegetative reproduction.
