Problem
Threatened temperate grassland habitats
Other Names:
Threatened cool grassland/scrub habitatsEndangered montane steppe habitats
Threatened temperate grasslands under threat
Savannah habitats under threat
Endangered open veld grasslands
Threatened prairie habitats
Incidence:
Few natural prairie regions in North America remain (only 1%) because most have been turned into farms or grazing land. This is because they are flat, treeless, covered with grass, and have rich soil. Conversion to agricultural land has been aided by the development of the steel plough. In the 1970s the USA deliberately reversed longstanding policy that favoured conservation practices such as fence rows, windbreaks, crop rotation and fallow land, and advised farmers to plough fence row to fence row and blanket the grasslands with wheat and corn. In Iowa, for example, less than 1 percent of the original tall-grass prairie and savannah habitat survived in 1995.
