Moorland

earth science Maturity 7-9 Next article →

Moorland is a specialized habitat found in upland areas across the globe. These environments exist within temperate grasslands, savannas, and shrublands. They also appear in the biomes of montane grasslands and shrublands. A defining feature of moorland is its low-growing vegetation. This plant life grows in acidic soils, which means the soil has a low pH. While many people associate moorland with high hill land, it can also include low-lying wetlands.

These habitats are closely related to heathland. Experts often debate the exact distinction between them. Generally, the term "moor" refers to highland areas with high rainfall. In contrast, "heath" often refers to lowland zones that may result from human activity.

The ecology of a moorland is shaped by its harsh conditions. The chemically difficult soil and unique microclimates often lead to high endemism. Endemism occurs when species live in one specific place and nowhere else. For example, the Exmoor Pony is a rare horse breed from England. This animal has adapted to the difficult conditions of the Exmoor moor.

In Europe, many bird species call the moor home. These include the red grouse, hen harrier, merlin, and golden plover. You might also find the curlew, skylark, meadow pipit, whinchat, ring ouzel, and twite. While amphibians like frogs are common, reptiles are often rare due to the cool temperatures. In Europe, the common viper is one of the few frequent reptiles.

Vegetation types vary significantly depending on the geographic region. In eastern Britain, moors are distinguished by a covering of peat. Peat is a thick layer of organic matter. On western moors, this peat layer can reach a thickness of several metres. Scottish "muirs" are typically heather moors. These areas also feature grass, cotton-grass, mosses, and bracken. In wetter areas, sphagnum moss may merge into bog-land.

In the tropics, moorland biodiversity can be extremely high. This habitat is also related to the tundra. The boundary between tundra and moorland shifts constantly due to climatic change.

Humans have played a role in shaping these landscapes for centuries. There is uncertainty regarding how much human activity created modern moors. The writer Oliver Rackham used pollen analysis to study this history. He found that some northern Scottish islands are naturally treeless. However, much of the Pennine moorland was forested during the Mesolithic era. It remains unclear if deforestation was caused by climate change or human actions. Management of these lands is a complex and sometimes controversial task.

One common management method is the controlled burning of vegetation. This practice has been recorded in Britain since the fourteenth century. Managers often burn heather when it is 10 or 12 years old. At this age, the plant's regenerative capacity is at its best. However, if heather stems are left to mature longer, they burn more aggressively. This can hinder the plant's ability to grow back.

Uncontrolled burning is dangerous because the peat itself can catch fire. Peat fires are notoriously difficult or even impossible to extinguish. Some experts, including Rackham, describe burning as "second-best land management." If burning is not controlled, it can encourage the growth of bracken and coarse grasses.

Mechanical cutting is another method used in Europe to manage heather. For this to work, the cut material must be removed to prevent choking new growth. If vegetation is left to grow too long, dry material accumulates. This buildup can lead to intense wildfires. Interestingly, heather seeds sometimes germinate better after experiencing the brief heat of a controlled burn. Managing moorland for wildlife requires balancing many different needs. For instance, predator control can help increase the numbers of red grouse and curlew.

Moorlands are found in diverse locations with many different names. In Italy, they are called "brughiera," named after the plant *Calluna vulgaris*. In Spain, these habitats are known as "páramos." Colombia is home to more than 60% of the world's tropical moorland, or "páramo." In South America, Brazil has "Campos Rupestres," which are rocky, misty grasslands. Great Britain contains an estimated 10% to 15% of the world's moors. These landscapes have even inspired famous literature, from the rugged settings in *Wuthering Heights* to the mysteries of *The Hound of the Baskervilles*.
