Diameter at breast height, or DBH, is a standard method of expressing the diameter of the trunk or bole of a standing tree. DBH is one of the most common dendrometric measurements. Electronic calipers can measure diameter at breast height and send measured data via Bluetooth to a field computer .
An estimate of the value and possible uses of timber is an important part of the broader information required to sustain ecosystems. [1] [2] When taking forest inventory the following are important things to measure and note: species, diameter at breast height (DBH), height, site quality, age, and defects.
Syzygium cormiflorum can grow as a tall rainforest tree to 30 m (98 ft) in height with a trunk 1 m (3 ft 3 in) diameter at breast height (dbh). Trees with flowers on branches grow larger than those with flowers on the trunk. The trunk in the latter form has a pronounced bumpy texture. Large specimens can have buttressed trunks.
Weeding: A process of getting rid of saplings' or seedlings' competition by mowing, application of herbicide, or other method of removal from the surroundings. [89] Cleaning: Release of select saplings from competition by overtopping trees of a comparable age. The treatment favors trees of a desired species and stem quality.
A prefix meaning "two", e.g. bisulcate, having two sulci or grooves. biennial A plant which completes its life cycle (i.e. germinates, reproduces, and dies) within two years or growing seasons. Biennial plants usually form a basal rosette of leaves in the first year and then flower and fruit in the second year. bifid
A seedling is a young sporophyte developing out of a plant embryo from a seed. Seedling development starts with germination of the seed. A typical young seedling consists of three main parts: the radicle (embryonic root), the hypocotyl (embryonic shoot ), and the cotyledons (seed leaves).
Tabebuia rosea, also called pink poui, and rosy trumpet tree [2] is a neotropical tree that grows up to 30 m (98 ft) and can reach a diameter at breast height of up to 100 cm (3 ft). The Spanish name roble de sabana , meaning "savannah oak", is widely used in Costa Rica , probably because it often remains in heavily deforested areas and because ...
The base of a Yellow Birch trunk. In botany, the trunk (or bole) is the stem and main wooden axis of a tree, [1] which is an important feature in tree identification, and which often differs markedly from the bottom of the trunk to the top, depending on the species.
