| Tóm tắt: | The 'grassland' biome, defined as permanent
vegetation of herbaceous plant communities,
covers approximately 25% of the terrestrial
Earth surface, approximately equivalent to
the area of forest lands or the area of
cultivated lands. Among the different types
of grassland ecosystems, it is important to
distinguish: (i) the climatically determined
grasslands, in areas where water availability
is not enough to allow the development of
forest ecosystems and where natural
vegetation remains at the herbaceous
succession stage in dynamic equilibrium
with herbivores (Lauenroth, 1979); and (ii)
the anthropogenic grasslands, mainly
located within temperate climate regions,
where woody vegetation is excluded and
herbaceous plant communities are main-
tained by means of human management for
domestic herbivore production. Among
these anthropogenic grasslands it is also
possible to distinguish long-term natural-
ized grasslands from cultivated grasslands
with a wide range of variation in degree of
intensification. All these grasslands play an
important role in agronomic, economic and
social activities in the exploitation of their
resources by domestic herbivores for food
and fibre production. |
