Globally, temperate grasslands face, more or less, common threats. In short, they have all been over-exploited by people through the persuits of agricultural production and infrastructure development. In Australia virtually no example of temperate grassland is currently in the condition it was in 1750 (i.e. pre-European invasion). Existing temperate grasslands, of which about 1% of the original remains, are mostly in a highly modified state. Many ecosysytem components (such as most mammals and some birds, insects and plants) have been lost, and this has vastly altered most of the ecological processes within these grasslands. The most important threats and 'damage caused' are summarised below:
1. Clearance. Catastrophic - the whole ecosystem is lost. Examples; car park construction or sustained cropping (ploughing).
2. Fragmentation. Is a consequence of clearing. Remaining patches become smaller and further separated from one another. Smaller and further separated patches tend to support fewer species. Many ecosystem processes 'break down' as interdenpdant plants and animals disappear. Chain reaction of sorts.
3. Overgrazing. Sustained heavy grazing by domestick stock (sheep & cattle) and feral animals (rabbits) leads to the loss of many plant and animal species; and soil compaction by the former. Native mammals are either outcompeted for resources or deliberately exterminated (a continuing practice). Many birds, reptiles and insects disappear as overgrazing eliminates their habitat (only some species can survive in very short vegetation).
4. Weed invasion. Partly a consequence of the above. Various vigorous 'weed' plant species invade grasslands and displace native species (outcompete them); moreso in smaller highly disturbed patches. The majority of such invasions has been caused by deliberate weed introduction under the blanket term 'pasture improvement'. Weed invasion leads to the loss of many plant and animal species through habitat loss.
There are many more lesser threats to temperate grasslands. It should be stressed though, that no particular threat acts in isolation. They are interconnected and act together. The net result is grassland patches that become increasingly smaller, homogenous (lacking in variation) and simplified (fewer species, fewer ecological processes).

How do plants live in the temperate grassland?

Grasses dominate temperate grasslands. Some of them include, purple needle grass, wild oats, foxtail, ryegress, or buffalo grass. They survive because of the growth point on t

What are some plants found in temperate grasslands?

buffalo grass, ryegrass, foxtail, wild oats, and purple  needlegrass.    There are also many types of wildflowers that grow in temperate  grasslands, such as wild ind

What are some examples of commensalism in temperate grasslands?

A good example would be when the killdeer bird rests on top of a cape buffalo. the cape buffalo protects the killdeer but the killdeer doesnt really do anything for the buffal

Abiotic factors of temperate grassland?

Abiotic factors are components within an ecosystem that are  non-living, yet affect all living things in that ecosystem. Some  abiotic factors of a temperate grassland would

What are the temperate grasslands?

Temperate grasslands, found on almost all continents (prairies of North America, all across Europe, most of Australia, and parts of South America) are important due to their a
