VEGETATION OF THE EARTH IS DIVIDED:
horizontally – plant areas and vegetation zones
vertically – altitudinal zonation – elevation levels
REGIONAL PHYTOGEOGRAPHY
examines the various flora phytogeographical areas
PLANT AREAS
the highest phytogeographical units divided into sub-regions, provinces
AREAS
Holarctic Palaeotropical Neotropical Australian Cape Antarctic
VEGETATION ZONATION
an inevitable extension of vegetation depending on latitude
from the equator to the poles we can see coherent and parallelly organized
VEGETATION ZONES
THE BELT OF TROPICAL RAINFORESTS
equatorial regions balanced climate, the average temperature
24-29ºC even abundant rainfalls diverse vegetation, dominated by trees
THE BELT OF DECIDUOUS AND SEMI-DECIDUOUS FORESTS
it follows the tropical rain forests on the southern and northern hemisphere temperature differences between the cold
season and the warm season irregular rainfalls
THE SAVANNAH BELT
tropical and subtropical areas of the southern hemisphere
the rainy season 2-4 months the tall grass vegetation, sparsely scattered
shrubs or trees
THE BELT OF DESERTS AND SEMI-DESERTS
in the tropics, subtropics and temperate regions
a small amount of precipitation large temperature differences between day
and night very sparse vegetation
THE BELT OF FOREST WITH HARD LEAVES AND THEIR ALTERNATIVE COMMUNITIES.
areas with maximum precipitation in winter and very dry and warm summers (eg. California, Mediterranean)
original vegetation - evergreen forests current vegetation - scrub communities
THE BELT OF DECIDUOUS BROAD-LEAVED FORESTS.
temperate zones of the northern hemisphere winter lasts 3-4 months deciduous trees
THE BELT OF STEPPES
in extratropical areas little rain vegetation - grasses, herbs The Central Asia, Ukraine, North America
(prairie), South America (pampas)
THE NORTHERN BELT OF CONIFEROUS FORESTS
Northern Europe, Asia, North America characterized by large fluctuations in
temperature spruce, pine, fir, larch northern boundary of the forest
THE BELT OF TUNDRA
a northern hemisphere a short growing season and low summer
temperatures mosses, lichens, shrubby birches, willows
WORKSHEET - REVISION
How to divide vegetation on Earth? What does regional phytogeography study? What are the plant areas? Which plant areas do we know and what is
characteristic for each of them ?
