Summary: 4 &Backyards Beyond
Grasslands or Shrubland?Tipping the Balance
Introduction
Grasslands and savannas (grasslands with
scattered shrubs or trees) constitute about 50%
of the Earth's land surface. Characterized by low
and highly variable rainfall, these ecosystems
account for about one-third of plant production
on land, contain about one-third of the world's
human population and support the majority of
the world's livestock production. Their extensive
airsheds and watersheds provide habitat for
game and non-game wildlife and a myriad
of ecosystem goods and services important
to rapidly growing settlements and cities that
may be geographically distant. Grasslands
and savannas thus have considerable, multi-
dimensional conservation value.
Astriking change in grasslands worldwide
in recent decades has been the proliferation
