Tolerant, a. Capable of enduring more or less heavy shade. 



Sjm.: shade-bearing, shade-enduring. G., Schattenertragend. F., a tempera- 

 ment deUcat. 

 Total increment. The total volume of wood produced by the growth of a tree or 



stand up to the time it is cut. 

 Town forest. A forest which is the property of a city, town, or village.

 Transplant, v. 1. To take up a young tree and set it out again in another place.

Transplant, n. A seedling which has been transplanted once or several times. 

 G., Schulpflanze. F., plant repique. 



Trap tree. A tree deadened or felled at a time when destructive bark beetles will 

 be attracted to it and enter the bark. After they have entered, the bark is peeled 

 and exposed to the sun, burned, or buried, as the case may require, to destroy the 

 insect. 



G., Fangbaum. F., arbre-piege. 



Tree analysis. A series of measurements and observations upon a felled tree to 

 determine its growth and life history. 



Syn. : stem analysis. G., Stammanalyse. F., analyse de tige. 



Tree analyses vary with their purpose, and may include all or a part of the fol- 

 lowing, or may require additions to meet special needs. The usual measure- 

 ments comprise the length of each section, the diameter inside and outside the 

 bark, the total age, the age and width of the sapwood, the diameter growth at 

 given periods on the upper end of each section, the diameter breasthigh, the 

 total height, and the clear, used, and merchantable lengths. The observations 

 determine the class, form, and condition of the tree. 



Although a tree analysis may include many combinations of the above measure- 

 ments, two important classes are distinguished: 



A stump analysis includes measurements of the diameter growth at given periods 

 upon the stump only, no matter what other measurements it may comprise. 



A section analysis includes measurements of the diameter growth at given periods 

 upon more than one section. 



When, in a stump or section analysis, the measurement of the diameter growth 

 at given periods covers only a portion of the total diameter growth, the analysis 

 is a partial stamp analysis or a partial section analysis. 



Tree class. All trees of approximately the same size. The following tree classes are 

 distinguished : seedling, shoot, small sapling, large sapling, small pole, large pole, stand- 

 ard, veteran. 



Tree form factor. See Form factor. 



Tree scribe. See Scratcher. 



Trench planting-. A method of planting on dry ground, in which the seeds of 

 young trees are set in pits or trenches. 

 Syn. : pit planting. 



Triang-ular planting*. A method of planting in which the unit of arrangement is 

 an equilateral triangle, at each apex of which young trees are placed. 

 G., Dreieckverband. F., plantation en triangle. 



Trunk, n. See Stem.
