In biology, the canopy is the aboveground portion of a plant cropping or crop, formed by the collection of individual plant crowns. [ 1 ] [ 2 ] [ 3 ] In forest ecology , the canopy is the upper layer or habitat zone, formed by mature tree crowns and including other biological organisms ( epiphytes , lianas , arboreal animals , etc..).

Hemispherical photograph used to study microclimate of winter roosting habitat at the Monarch Butterfly Biosphere Reserve, Mexico.. Hemispherical photography, also known as canopy photography, is a technique to estimate solar radiation and characterize plant canopy geometry using photographs taken looking upward through an extreme wide-angle lens or a fisheye lens (Rich 1990).
The building phase is the period when the seeding attain canopy status. The mature phase is the period when the canopy keep intact. The average height of this plant is 15 cm per year (range 10–18 cm). [14] The flowers are borne on the slim twigs and they are very small, the color is green, they always appear from late spring to mid-summer. [4]
Canopy mapping is the process whereby the positions and size of the branches within the canopy are mapped in three-dimensional space. [22] [23] [24] It is a labor-intensive process that usually reserved for only the most significant specimens. This is usually done from a set position or a series of positions within the tree.
The canopy level is the third level of the temperate rainforest. The trees forming the canopy, conifers, can stand as tall as 100 metres or more. A variety of species survive in the canopy. The tops of these trees collect most of the rain, moisture, and photosynthesis that the rainforest takes in. They form a canopy over the forest, covering ...
Leaf area index (LAI) is a dimensionless quantity that characterizes plant canopies. It is defined as the one-sided green leaf area per unit ground surface area (LAI = leaf area / ground area, m 2 / m 2) in broadleaf canopies. [1] In conifers, three definitions for LAI have been used: Half of the total needle surface area per unit ground ...
A major grower said this week it was abandoning its citrus growing operations, reflecting the headwinds Florida's signature crops are facing following a series of hurricanes and tree diseases.
The crown of a woody plant (tree, shrub, liana) is the branches, leaves, and reproductive structures extending from the trunk or main stems. Shapes of crowns are highly variable. The major types for trees are the excurrent branching habit resulting in conoid shapes and decurrent (deliquescent) branching habit, resulting in round shapes.
