grassland : an ecological community in which the characteristic plants are grasses — Webster
Grasslands are areas where the vegetation is dominated by grasses (Poaceae); however, sedge (Cyperaceae) and rush (Juncaceae) families can also be found along with variable proportions of legumes, like clover, and other herbs. Grasslands occur naturally on all continents except Antarctica. Grasslands are found in most ecoregions of the Earth. For example, there are five terrestrial ecoregion classifications (subdivisions) of the temperate grasslands, savannas, and shrublands biome (ecosystem), which is one of eight terrestrial ecozones of the Earth’s surface. — Wikipedia

Ecosystems have a variety of benefits to humans, including food, water and other resources, as well as recreational space.

Ecologists at the University of Zurich and the Swiss Federal Institute of Aquatic Science and Technology (Eawag) have now examined the factors that influence this stability in a unique and comprehensive experiment.

The Copernicus Sentinel-2B satellite takes us over South Sudan. Having gained independence from Sudan in July 2011, South Sudan is the youngest country in the world. It has an estimated population of 13 million people, more than 80% of whom live in rural areas. Most of the population relies on farming, fishing or herding to meet their food and income needs. […]

Leek orchids don't have many friends. Maybe it's because they lack the drop-dead gorgeous looks of many of their fellow family members. Or perhaps it's because they're always the first to leave the party: as soon as sheep or weeds encroach on their territory, they're out of there. Whatever the reason, you don't see leek orchids around very often. […]
