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.
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 .
The seedlings of some flowering plants have no cotyledons at all. These are said to be acotyledons. The plumule is the part of a seed embryo that develops into the shoot bearing the first true leaves of a plant. In most seeds, for example the sunflower, the plumule is a small conical structure without any leaf structure. Growth of the plumule ...
A plant derived from the asexual vegetative reproduction of a parent plant, with both plants having identical genetic compositions. coalescent Having plant parts fused or grown together to form a single unit. cochleariform Concave and spoon-shaped. cochleate Coiled like a snail's shell. coenobium An arranged colony of algae that acts like a ...
Tree girth measurement diagram. Tree girth is a measurement of the circumference of tree trunk. It is one of the most ancient, quickest, and simplest of foresters' measures of size and records of growth of living and standing trees.
Groundcover: Delosperma (Delosperma), also known as ice plant, is a low-growing succulent with flowers that appear from spring to fall in brilliant neon colors, including hot pink, orange, and purple.
Non-vascular plants , with their different evolutionary background, tend to have separate terminology. Although plant morphology (the external form) is integrated with plant anatomy (the internal form), the former became the basis of the taxonomic description of plants that exists today, due to the few tools required to observe.

Information on the establishment, survival and growth of seedlings influenced by the cover of shelter trees, as well as on the growth of these trees, is needed as a basis for modelling the economic return of practising a shelterwood system. [144] The method's objective is to establish new forest reproduction under the shelter of the retained trees.
