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 research is a relatively new scientific field which was hampered for a long time by lack of means of access to the tree canopies and lack of appropriate means of housing researchers. Climbing gear, tree houses , canopy walkways , cranes , airships and inflatable platforms resting on the treetops have lately overcome these barriers.
The canopy layer contains the majority of the largest trees, typically 30 metres (98 ft) to 45 metres (148 ft) tall. The densest areas of biodiversity are found in the forest canopy, a more or less continuous cover of foliage formed by adjacent treetops. The canopy, by some estimates, is home to 50 percent of all plant species.
Forest with canopy, shrub and herb layers of vegetation. The following layers are generally distinguished: forest floor (root and moss layers), herb, shrub, understory and canopy layers. These vegetation layers are primarily determined by the height of their individual plants, the different elements may however have a range of heights.
A liana is a long-stemmed woody vine that is rooted in the soil at ground level and uses trees, as well as other means of vertical support, to climb up to the canopy in search of direct sunlight. [1] The word liana does not refer to a taxonomic grouping, but rather a habit of plant growth – much like tree or shrub .
The average tree canopy is rated at 55% of land. This average puts Tallahassee close to number one in the nation for urban forest coverage. One problem with our forest is the lack of diversity in ...
Ecnomiohyla rabborum, like other members of the genus, lived in the forest canopy. They were nocturnal and fed on insects. [5] When threatened, they were capable of gliding through the air by leaping from their perch and fully stretching their massive webbed hands and feet. [4] They could also steer the direction of their descent.
Treefall gaps in the Amazon allow sunlight to reach the forest floor. Gap dynamics refers to the pattern of plant growth that occurs following the creation of a forest gap, a local area of natural disturbance that results in an opening in the canopy of a forest. Gap dynamics are a typical characteristic of both temperate and tropical forests ...
