Tree Grate
A tree grate is a metallic grating A grating is any regularly spaced collection of essentially identical, parallel, elongated elements. Gratings usually consist of a single set of elongated elements, but can consist of two sets, in which case the second set is usually perpendicu ... installed at the same level with the pavement around a tree that allows the soil underneath to stay uncompacted and the pedestrians to walk near the tree without stepping on the soil. Grate slots allow tree roots to absorb air, sunlight, and water, meanwhile its soil is protected from pedestrian traffic impact. Tree grates create a protective barrier, providing uncompacted soil and development space for tree roots. They also serve as a decorative element along ceremonial streets, matching a street's design style and personality.

But wider definitions include taller palms, tree ferns, bananas, and bamboos. Trees are not a monophyletic taxonomic group but consist of a wide variety of plant species that have independently evolved a trunk and branches as a way to tower above other plants to compete for sunlight. The majority of tree species are angiosperms or hardwoods; of the rest, many are gymnosperms or softwoods. Trees tend to be long-lived, some trees reaching several thousand years old. Trees evolved around 400 million years ago, and it is estimated that there are around three trillion mature trees in the world currently. A tree typically has many secondary branches supported clear of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
