Most scenery generators can create basic heightmaps to simulate the variation of elevation in basic terrain. Common techniques include Simplex noise, fractals, or the diamond-square algorithm, which can generate 2-dimensional heightmaps. A version of scenery generator can be very simplistic.
On the one hand, the researchers found, trees in forests "desire" to grow as tall as possible to overtake neighboring trees and reach stronger sunlight. On the other hand, gravity makes it more and more difficult to haul water upwards from the roots to the canopy as the tree grows, and leaves thus become smaller near the top. They discovered ...
An alpine tree line is the highest elevation that sustains trees; higher up it is too cold, or the snow cover lasts for too much of the year, to sustain trees. [ 2 ] : 151 The climate above the tree line of mountains is called an alpine climate , [ 14 ] : 21 and the habitat can be described as the alpine zone . [ 15 ]
Tree heights can be directly measured using a pole for shorter trees, or by climbing a larger tree and measuring the height via a long measuring tape. Pole measurements [30] [31] work well for small trees eliminating the need for trigonometry involving multiple triangles, and for trees shorter than the minimal range for laser rangefinders ...
There are direct measurements. Shorter trees can be measured using a long pole extended vertically to the top of the tree. Larger trees can be climbed and a tape measurement made from the highest point of the climb to the base of the tree. The distance to the top of the tree can be measured from that point, if needed, using a pole.

Each of the trees in this stand is a genetically identical male that has reproduced vegetatively. Although no single tree in this stand is of that age, the stand itself as a single organism has existed that long. [119] Individual trees in the clonal patch have been listed as having ages of 2000 [120] [121] or even to 3000 years old. [122] [123]
[4]: 223 [6]: 151 Also growing to 14,000 feet (4,300 m) elevation is the shorter rambling fleabane , which grows in talus and only gets 2 inches (5.1 cm) tall. [ 6 ] : 151 dwarf daisy, ( E. pygmaeus ), grows from a woody taproot as a compact, cushion forming plant that can be found on rocky slopes and flats from 9,500 to 13,500 feet (2,900 to ...
