Vegetation indices classification is a system in which two or more spectral bands are combined through defined statistical algorithms to reflect the spatial properties of a vegetation cover. Most of these indices make use of the relationship between red and near-infrared (NIR) bands of satellite images to generate vegetation properties. Several ...
Vegetation is an assemblage of plant species and the ground cover they provide. [2] It is a general term, without specific reference to particular taxa , life forms, structure, spatial extent, or any other specific botanical or geographic characteristics.
Plant cover data may be used to classify the studied plant community into a vegetation type, to test different ecological hypotheses on plant abundance, and in gradient studies, where the effects of different environmental gradients on the abundance of specific plant species are studied .
Due to its substantial length of over 3,000 km from north to south and its mountain ranges that can exceed 3,000 meters, Japan's vegetation varies by latitude and by altitude. Evergreen forests tend to appear in the southern half of the Japanese mainland, with broad leaf forests, subalpine, and alpine appearing with increasing frequency to the ...
Temperate deciduous forest canopy gaps and vegetation strata Temperate deciduous forests are characterized by a variety of temperate deciduous tree species that vary based on region. [ 6 ] Most tree species present in temperate deciduous forests are broadleaf trees that lose their leaves in the fall, [ 8 ] though some coniferous trees such as ...
Treeless alpine (low-alpine): Characterized by a closed carpet of vegetation that includes alpine meadows, shrubs and sporadic dwarfed trees. Because of the complete cover of vegetation, frost has less of an effect on this region, but due to the consistent freezing temperatures tree growth is severely limited.
This layer contains mostly non-woody vegetation, or ground cover, growing in the forest with heights of up to about one and a half metres. The herb layer consists of various herbaceous plants ( therophytes , geophytes , cryptophytes , hemicryptophytes ), dwarf shrubs ( chamaephytes ) as well as young shrubs or tree seedlings .
Caatinga (Portuguese pronunciation: [kaaˈtʃĩɡɐ]) is a type of semi-arid tropical vegetation, and an ecoregion characterized by this vegetation in interior northeastern Brazil. The name "Caatinga" comes from the Tupi word ka'atinga , meaning "white forest" or "white vegetation" ( ka'a = forest, vegetation, tinga = white).
