Grassland landscape is a very important topic in the study of the ecosystem because grasslands cover nearly one third of the earth’s land surface and supply three quarters of the energy that the world needs. Grasslands can be divided into two types: savannas and temperate grasslands, but both types have some similar features in several aspects.
Generally, grasslands are open and continuous areas made up of many different kinds of grasses, like, Cocksfoot, Upright Brome, Tor Grass, Sheep's Fescue, Crested Dog's-tail, Common Quaking-grass, Common Fox-tail, Rough Meadow Grass, False Oat-grass, Blue Moor-grass and Yorkshire Fog. Also, there are various types of grassland flowers such as Salad Burnet, Meadow Buttercup, Red Campion, Cuckoo Flower, Cowslip, Sainfoin, Field Gentian, Meadow Saffron, Harebell, Knapweed and Bee Orchid. Besides plants, there are also a huge number of animals and many of them have their own survival mechanism to escape from their enemies and to adapt to the environment.
Grasslands are very important to human because crops can be grown on them to provide the food that people need. Sometimes, sunflowers, linseed and lupins are especially grown for the oil in their seeds. Grasslands also benefit other animals by providing them with their habitats and food. With the interaction between grasslands and animals, the existence of grasslands is made possible because without the grazing by animals, they will be colonized by shrubs quickly and become woodland.
