Clover in the context of "Fires"

A grassland is an area (or ecosystem) where the vegetation is dominated by grasses. However, sedges and rushes can also be found along with variable proportions of legumes such as clover, and other herbs. Grasslands occur naturally on all continents except Antarctica and are found in most ecoregions of the Earth. Furthermore, grasslands are one of the largest biomes on Earth and dominate the landscape worldwide. There are different types of grasslands: natural grasslands, semi-natural grasslands, and agricultural grasslands. They cover 31–69% of the Earth's land area.

Fire is the rapid oxidation of a fuel in the exothermic chemical process of combustion, releasing heat, light, and various reaction products.Flames, the most visible portion of the fire, are produced in the combustion reaction when the fuel reaches its ignition point temperature. Flames from hydrocarbon fuels consist primarily of carbon dioxide, water vapor, oxygen, and nitrogen. If hot enough, the gases may become ionized to produce plasma. The color and intensity of the flame depend on the type of fuel and composition of the surrounding gases.

Fire, in its most common form, has the potential to result in conflagration, which can lead to permanent physical damage. It directly impacts land-based ecological systems worldwide. The positive effects of fire include stimulating plant growth and maintaining ecological balance. Its negative effects include hazards to life and property, atmospheric pollution, and water contamination. When fire removes protective vegetation, heavy rainfall can cause soil erosion. The burning of vegetation releases nitrogen into the atmosphere, unlike other plant nutrients such as potassium and phosphorus which remain in the ash and are quickly recycled into the soil. This loss of nitrogen produces a long-term reduction in the fertility of the soil, though it can be recovered by nitrogen-fixing plants such as clover, peas, and beans; by decomposition of animal waste and corpses, and by natural phenomena such as lightning.

Revegetation is the process of replanting and rebuilding the soil of disturbed land. This may be a natural process produced by plant colonization and succession, manmade rewilding projects, accelerated process designed to repair damage to a landscape due to wildfire, mining, flood, or other cause. Originally the process was simply one of applying seed and fertilizer to disturbed lands, usually grasses or clover. The fibrous root network of grasses is useful for short-term erosion control, particularly on sloping ground. Establishing long-term plant communities requires forethought as to appropriate species for the climate, size of stock required, and impact of replanted vegetation on local fauna. The motivations behind revegetation are diverse, answering needs that are both technical and aesthetic, but it is usually erosion prevention that is the primary reason. Revegetation helps prevent soil erosion, enhances the ability of the soil to absorb more water in significant rain events, and in conjunction reduces turbidity dramatically in adjoining bodies of water. Revegetation also aids protection of engineered grades and other earthworks.

Organisations like Trees For Life (Brooklyn Park) provide good examples.

A volute is a spiral, scroll-like ornament that forms the basis of the Ionic order, found in the capital of the Ionic column. It was later incorporated into Corinthian order and Composite column capitals. Four are normally to be found on an Ionic capital, eight on Composite capitals and smaller versions (sometimes called helix) on the Corinthian capital.

The word derives from the Latin voluta ("scroll"). It has been suggested that the ornament was inspired by the curve of a ram's horns, or perhaps was derived from the natural spiral found in the ovule of a common species of clover native to Greece. Alternatively, it may simply be of geometrical origin.

The four-leaf clover is a rare mutation of the common three-leaf clover that has four leaflets instead of three. According to traditional sayings, such clovers bring good luck, a belief that dates back to at least the 17th century.

The term four-leaf is botanically a misnomer, as cloverplants have multiple leaves (multiple clovers), each consisting of a varying number of leaflets, typically three.

A shamrock is a type of clover, used as a symbol of Ireland. The word shamrock comes from Irish seamróg ([ˈʃamˠ.ɾˠoːɡ]), which is the diminutive of the Irish word seamair and simply means "young clover".

At most times, Shamrock refers to either the species Trifolium dubium (lesser/yellow clover, Irish: seamair bhuí) or Trifolium repens (white clover, Irish: seamair bhán). However, other three-leaved plants—such as Medicago lupulina, Trifolium pratense, and Oxalis acetosella—are sometimes called shamrocks. The shamrock was traditionally used for its medicinal properties, and was a popular motif in Victorian times.

Melilotus, known as melilot or sweet clover is a genus of legumes in the family Fabaceae, native to Europe, Asia, and Africa. The genus is closely related to Trifolium (clovers). Several species are common grassland plants and weeds of cultivated ground, and some species are now found worldwide as naturalised plants.

The scientific and English names both derive from Greek melílōtos from méli (honey), and lōtos (lotus), via Latin melilōtos and Old French mélilot. The alternative name "sweet clover" varies in orthography, also cited as sweet-clover and sweetclover. Other names include "kumoniga", from the Cumans.

Medicago is a genus of flowering plants, commonly known as medick or burclover, in the legume family (Fabaceae). It contains at least 87 species and is distributed mainly around the Mediterranean Basin, and extending across temperate Eurasia and sub-Saharan Africa. The best-known member of the genus is alfalfa (M. sativa), an important forage crop, and the genus name is based on the Latin name for that plant, medica, from Greek: μηδική (πόα) Median (grass). Most members of the genus are low, creeping herbs, resembling clover, but with burs (hence the common name). However, alfalfa grows to a height of 1 meter, and tree medick (M. arborea) is a shrub. Members of the genus are known to produce bioactive compounds such as medicarpin (a flavonoid) and medicagenic acid (a triterpenoid saponin). Chromosome numbers in Medicago range from 2n = 14 to 48.

The species Medicago truncatula is a model legume due to its relatively small stature, small genome (450–500 Mbp), short generation time (about 3 months), and ability to reproduce both by outcrossing and selfing.
