problem is native grasses and their soil-retaining roots being eradicated. Due
to dust and erosion fallow plowed lands lose topsoil. Especially wind erosion
events can cause a change of landscapes and damage to plants.
problem is Overgrazing as for example cattle and sheep are often used to graze
land. Unfortunately they eat all the grass faster than it can grow. A solution
therefore would be the use of American bisons as they also eat other plants
than grass, at least in North America, so it has enough time to grow. For
native species Overgrazing destroys habitat, waterways with runoff are polluted
and soil is washed away at the end.
problem is the fact that the majority of all temperate grasslands became
croplands, forest plantations, grazing lands or urban and industrial areas.
problem is Global Warming causing that current marginal grasslands eventually
turn into deserts as rainfall patterns change.
all these problems are the continued education efforts on the protection of
soil and the prevention of soil erosion. Protecting and restoring wetlands
being an important part of grassland ecology can also solve the problem of soil
loss. Other good ideas are to prevent the sapping of nutrients, the rotation of
agricultural crops and planting trees as windbreaks. The last solution would be
to conduct dry seasons burning to obtain fresh growth and as calcium builds up
in the dry grasses some of it should be restored in the soil as well.
