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.). [4] .

Canopy trees define a forest more than anything else. The Northeastern forest is mostly deciduous. Trees drop their leaves in winter, and sunlight reaches the forest floor before the trees leaf out in late spring. This allows for spring ephemerals, which go dormant in late spring, to share the space on the forest floor with the trees above.

The canopy, where more species live than anyplace else in the rainforest, is the denser layer of greenery about 20 feet thick formed by the next tallest trees. It acts like a roof over the rest of the rainforest.

2023年4月23日 · 有效冠层覆盖度，英文常称为 effective canopy cover，很多文献也采用 foliage projective cover 、 canopy element cover，定义为：单位水平地表面积上 植被冠层元素 的垂直投影面积。 The vertical projection area of overstory (e.g., forest) or aboveground (e. g., cropland) vegetation elements per unit horizontal ground surface area. 需要注意的是： 对于农作物、草地来说，有效冠层覆盖度完全等同于植被覆盖度，而对于森林来说，有效冠层覆盖度通常特定指的 …

The plant life of the canopy is nearly as rich due to the variety of epiphytes and lianas. CANOPY TREES. As a result of the crowded growing conditions, canopy trees only branch near the top of their long, pole-like trunks (which also make them good for timber).

2017年6月1日 · Forest canopies are dynamic interfaces between organisms and atmosphere, providing buffered microclimates and complex microhabitats. Canopies form vertically stratified ecosystems interconnected with other strata.

2022年11月1日 · RAINFOREST CANOPY TREES. The canopy is the most biodiverse layer of the rainforest, with a thickness ranging from 10 to 40 feet (3–12 m). Many species traditionally associated with the forest floor have adapted to life in the canopy, including frogs, crabs, anteaters, porcupines, and even some species of kangaroos.

The canopy layer of a forest ecosystem is not only the uppermost stratum but also a hub of biodiversity, characterized by its dense foliage and complex interactions among species. This layer plays a critical role in photosynthesis, as the vast majority of a forests biomass resides here, with trees often reaching heights of over 100 feet.

2024年1月7日 · The upper layer of a forest or jungle formed by branches and leaves where the treetops intertwine is known as the tree canopy. More than simply a referential term, tree canopies are unique ecosystems in which only certain types of life can thrive.

2020年7月16日 · Forest canopies are home to an estimated 50% of terrestrial biodiversity but remain relatively unexplored until just four decades ago. As one of the first global arbornauts, I share an abbreviated history of canopy science, and how treetop access has inspired forest conservation, especially in the tropics where forests remain relatively unexplored.
