The honey locust (Gleditsia triacanthos), also known as the thorny locust or thorny honeylocust, is a deciduous tree in the family Fabaceae, native to central North America where it is mostly found in the moist soil of river valleys. [4] Honey locust trees are highly adaptable to different environments, and the species has been introduced ...
Locust tree can mean: Any of a number of tree species in the genera Gleditsia or Robinia, including: Honey locust (Gleditsia triacanthos), a leguminous tree with pods having a sweet, edible pulp; Black locust (Robinia pseudoacacia), a leguminous tree with toxic pods; Water locust (Gleditsia aquatica), a leguminous tree with one seed per pod
The mean annual increment (MAI) or mean annual growth refers to the average growth per year a tree or stand of trees has exhibited/experienced up to a specified age. For example, a 20-year-old tree that has a stem volume of 0.2 m 3 has an MAI of 0.01 m 3 /year.
PAI may go negative if a tree loses volume due to damage or disease. Periodic annual increment is commonly used instead of current annual increment as a basis for computing growth per cent. Growth per cent indicates the rate of increase with relation to the wood capital required for its production, this is usually based on a single year's ...
When stocking, a tree's basal area is measured. The basal area is a cross-sectional area of the stump taken about 4.5 feet (1.4 m) above the ground. [7] The equation for calculating the basal area of trees in a stand is Basal Area = 0.005454 DBH 2, where DBH is the diameter of the tree at the aforementioned measuring height. [7]
Parkia biglobosa, the African locust bean, [3] is a perennial deciduous tree in the family Fabaceae. It is found in a wide range of environments in Africa and is primarily grown for its pods that contain both a sweet pulp and valuable seeds. Where the tree is grown, the crushing and fermenting of these seeds constitutes an important economic ...
By contrast, the (roughly) 300-year-old Ice Glen pine in Stockbridge, Massachusetts shows approximately half the annual growth rate of trees in the 90- to 180-year age range, averaging just 5.8 cubic feet (0.16 m 3) per year over a five-year monitoring period. Volume increased as a result of increases in both height and girth.
Cyrtacanthacris aeruginosa or simply green tree locust [1] [2] [3] is a large species of grasshopper that can be found in the grasslands [4] of Africa. They pertain to the genus Cyrtacanthacris and are composed by three subspecies, C. a. aeruginosa, C. a. flavescens and C. a. goldingi, all three of them descend from a unique ancestor. [5]
