Plantation

In modern use, the term usually refers only to large-scale estates. Nevertheless, before about 1800, it was the usual term for a farm of any size in the southern parts of British North America, with, as Noah Webster noted, "farm" becoming the usual term from about Maryland northward. It was used in most British colonies but very rarely in the United Kingdom itself in this sense. There, as also in America, it was used mainly for tree plantations, areas artificially planted with trees, whether purely for commercial forestry, or partly for ornamental effect in gardens and parks, when it might also cover plantings of garden shrubs.^[1]


Among the earliest examples of plantations were the latifundia of the Roman Empire, which produced large quantities of grain, wine, and olive oil for export. Plantation agriculture proliferated with the increase in international trade and the development of a worldwide economy that followed the expansion of European colonialism.

Ecological impact[edit]

Probably the most critical factor a plantation has on the local environment is the site where the plantation is established. In Brazil, coffee plantations would use slash-and-burn agriculture, tearing down rainforests and planting coffee trees that depleted the nutrients in soil.^[2] Once the soil had been sapped, growers would move on to another place. If a natural forest is cleared for a planted forest, then a reduction in biodiversity and loss of habitat will likely result. In some cases, their establishment may involve draining wetlands to replace mixed hardwoods that formerly predominated with pine species. If a plantation is established on abandoned agricultural land or highly degraded land, it can increase both habitat and biodiversity. A planted forest can be profitably established on lands that will not support agriculture or suffer from a lack of natural regeneration.


The tree species used in a plantation are also an important factor. Where non-native varieties or species are grown, few native faunas are adapted to exploit these, and further biodiversity loss occurs. However, even non-native tree species may serve as corridors for wildlife and act as a buffer for native forests, reducing edge effect.


Once a plantation is established, managing it becomes an important environmental factor. The most critical aspect of management is the rotation period. Plantations harvested on more extended rotation periods (30 years or more) can provide similar benefits to a naturally regenerated forest managed for wood production on a similar rotation. This is especially true if native species are used. In the case of exotic species, the habitat can be improved significantly if the impact is mitigated by measures such as leaving blocks of native species in the plantation or retaining corridors of natural forest. In Brazil, similar measures are required by government regulation.
