Shade (shadow) in the context of "Wooded"

A woodland (/ˈwʊdlənd/ ) is, in the broad sense, land covered with woody plants (trees and shrubs), or in a narrow sense, synonymous with wood (or in the U.S., the plurale tantum woods), a low-density forest forming open habitats with plenty of sunlight and limited shade (see differences between British, American and Australian English explained below). Some savannas may also be woodlands, such as savanna woodland, where trees and shrubs form a light canopy.

Woodlands may support an understory of shrubs and herbaceous plants including grasses. Woodland may form a transition to shrubland under drier conditions or during early stages of primary or secondary succession. Higher-density areas of trees with a largely closed canopy that provides extensive and nearly continuous shade are often referred to as forests.

A shadow is a dark area on a surface where light from a light source is blocked by an object. In contrast, shade occupies the three-dimensional volume behind an object with light in front of it. The cross-section of a shadow is a two-dimensional silhouette, or a reverse projection of the object blocking the light.

A canopy is a type of overhead roof or else a structure over which a fabric or metal covering is attached, able to provide shade or shelter from weather conditions such as sun, hail, snow and rain. They are frequently found at bus shelters and train station platforms. A canopy can also be a tent, generally without a floor.The word comes from the ancient Greek κωνώπειον (konópeion, "cover to keep insects off"), from κώνωψ (kónops, "cone-face"), which is a bahuvrihi compound meaning "mosquito". The first 'o' changing into 'a' may be due to influence from the place name Canopus, Egypt thought of as a place of luxuries.

Architectural canopies include projections giving protection from the weather, or merely decoration. Such canopies are supported by the building to which they are attached and often also by a ground mounting provided by not less than two stanchions, or upright support posts.

A shade house is a horticultural structure which provides a mix of shade and light to provide suitable conditions for shade-loving plants, or to reduce the temperatures under the cover. Typically it will have a frame which supports mesh fabric or wood lath.

Shade houses may also be used in commercial horticulture. For example, vanilla vines need 50% shade and, in deforested areas of Mexico, this is provided by shade houses of 1,000 – 10,000 square metres. These have tree-like support posts or actual living trees. From these, shade cloth walls of 3–5 metres height are suspended and these are black or red to cut the luminosity by half.

The heat index (HI) is an index that combines air temperature and relative humidity, in shaded areas, to posit a human-perceived equivalent temperature, as how hot it would feel if the humidity were some other value in the shade. For example, when the temperature is 32 °C (90 °F) with 70% relative humidity, the heat index is 41 °C (106 °F) (see table below). The heat index is meant to describe experienced temperatures in the shade, but it does not take into account heating from direct sunlight, physical activity or cooling from wind.

The human body normally cools itself by evaporation of sweat. High relative humidity reduces evaporation and cooling, increasing discomfort and potential heat stress. Different individuals perceive heat differently due to body shape, metabolism, level of hydration, pregnancy, or other physical conditions. Measurement of perceived temperature has been based on reports of how hot subjects feel under controlled conditions of temperature and humidity. Besides the heat index, other measures of apparent temperature include the Canadian humidex, the wet-bulb globe temperature, "relative outdoor temperature", and the proprietary "RealFeel".

In ecology, shade tolerance is a plant's ability to tolerate low light levels. The term is also used in horticulture and landscaping, although in this context its use is sometimes imprecise, especially in labeling of plants for sale in commercial nurseries.

Shade tolerance is a complex, multi-faceted property of plants. Different plant species exhibit different adaptations to shade, and a particular plant can exhibit varying degrees of shade tolerance, or even of requirement for light, depending on its history or stage of development.
