Meadow

In agriculture, a meadow is grassland which is not regularly grazed by domestic livestock, but rather allowed to grow unchecked in order to produce hay.

Especially in the United Kingdom and Ireland, the term meadow is commonly used in its original sense to mean a hay meadow, signifying grassland mown annually in the summer for making hay. Agricultural meadows are typically lowland or upland fields upon which hay or pasture grasses grow from self-sown or hand-sown seed.[1] Traditional hay meadows were once common in rural Britain, but are now in decline. Ecologist Professor John Rodwell states that over the past century, England and Wales have lost about 97% of their hay meadows.[2] Fewer than 15.000 hectares of lowland meadows remain in the UK and most sites are relatively small and fragmented. 25% of the UK's meadows are found in Worcestershire, with Foster's Green Meadow managed by the Worcestershire Wildlife Trust being a major site.[3]

A similar concept to the hay meadow is the pasture, which differs from the meadow in that it is grazed through the summer, rather than being allowed to grow out and periodically be cut for hay.[1] A pasture can also refer to any land used for grazing, and in this wider sense the term refers not only to grass pasture, but also to non-grassland habitats such as heathland, moorland and wood pasture.[4] The term, grassland, is used to describe both hay meadows and grass pastures.

The specific agricultural practices in relation to the meadow can take on various expressions. As mentioned, this could be hay production or providing food for grazing cattle and livestock but also to give room for orchards or honey production.

• 
  An uncut hay meadow.
• 
  Montane hay meadows with haystacks.
• 
  An orchard meadow.
• 
  A meadow (pasture) maintained by grazing livestock.
• 
  Artificially grazed meadow.
• 
  Artificial beehives.

A transitional meadow occurs when a field, pasture, farmland, or other cleared land is no longer cut or grazed and starts to display luxuriant growth, extending to the flowering and self-seeding of its grass and wild flower species.[5] The condition is however only temporary, because the grasses eventually become shaded out when scrub and woody plants become well-established, being the forerunners of the return to a fully wooded state.[6] A transitional state can be artificially-maintained through a double-field system, in which cultivated soil and meadows are alternated for a period of 10 to 12 years each.[5]

In North America prior to European colonization, Algonquians, Iroquois and other Native Americans peoples regularly cleared areas of forest to create transitional meadows where deer and game could find food and be hunted. For example, some of today's meadows originated thousands of years ago, due to regular burnings by Native Americans.[6][7]

A perpetual meadow, also called a natural meadow, is one in which environmental factors, such as climatic and soil conditions, are favorable to perennial grasses and restrict the growth of woody plants indefinitely.[8] Types of perpetual meadows may include:

• Alpine meadows occur at high elevations above the tree line and maintained by harsh climatic conditions.
• Coastal meadows maintained by salt sprays.
• Desert meadows restricted by low precipitation or lack of nutrients and humus.
• Prairies maintained by periods of severe drought or subject to wildfires.
• Wet meadows (a semi-wetland area) saturated with water throughout much of the year.
