Although climate is an important driver of grassland ecosystems,
disturbances such as fire and grazing
also play a key role in sustaining grasslands. … As climate conditions shift geographically so will the distributions of many plants and animals.
How does climate change affect the grasslands?
Drought is a major driver of impacts to grassland and prairie ecosystems, and is likely to lead to
increased wildfires and loss of wetland habitats
– such as prairie potholes that are critical habitat for migratory bird species – as well as species migration and habitat shifts. …

Why do the grasslands have an extreme climate?
Grasslands are generally open and continuous, fairly flat areas of grass. … While
temperatures are often extreme in some grasslands
, the average temperatures are about -20°C to 30°C. Tropical grasslands have dry and wet seasons that remain warm all the time.

What can we do to protect grasslands?
Rotate agricultural crops
to prevent the sapping of nutrients. Plant trees as windbreaks to reduce erosion on farmfields (though make sure it is the right species for the area). Conduct controlled dry season burning to stimulate fresh plant growth and to restore calcium to the soil that builds up in the dry grasses.
What will happen if grasslands disappear?
Along with pressing a threat towards wildlife, the loss of these grasslands can
put a limitation to the amount of clean drinking water we have
. With the loss of these lands, wildlife will be looking for new homes, effecting many other ecosystems.
What are the main features of grassland?
- Vegetation structure that is dominated by grasses.
- Semi-arid climate.
- Rainfall and soils insufficient to support significant tree growth.
- Most common at mid-latitudes and near the interiors of continents.
- Grasslands are often exploited for agricultural use.
What two factors are more important to grasslands?
The plants on grasslands have adapted to the
drought, fires, and grazing common
to that habitat. Fires, both natural and human-caused, are important factors shaping grasslands.
What are the functions of grassland ecosystem?

provides forage for livestock, protection and conservation of soil and water resources
, furnishing a habitat for wildlife, both flora and fauna and (contribution to the attractiveness of the landscape.
What is the role of sunlight in the grassland?
