REGIME AND EXPLOITAEILITY. 



oJ<Ko 



DEFINITIONS. 



By the term Forest Organisation we will designate the art of re- 

 gulating the treatment and working of forests. For each forest this 

 art determines, in the first place, the Regime, the Method op Treat- 

 ment and the Exploitabilitt to adopt in order to obtain from it 

 produce in the closest conformity possible with the interests of the 

 owner ; and, in the next place, it regulates the distribution and 

 extent of the Asxual Cuttings so as to ensure a Sustained Yield. 



The word Regime we wUl employ to express in a general man- 

 ner the system of culture applied to a forest ; it will be synonymous 

 with Method of Culture, of Working or of Exploitation. It is 

 in this sense that we may say, in speaking of a forest, that it is 

 subjected to the Regime of High Forest or to that of Coppice. 



The distinction between these two Regimes is founded on the 

 manner in which reproduction is obtained. If reproduction is 

 eflFected by leaving the forest entirely to itself, or by the natural or 

 artificial sowing of the ground, the forest is, according to our nomen- 

 clature, said to be under the Regime of High Forest. On the 

 other hand, if restocking is the result chiefly of reproduction from the 

 stools of trees cut, the Regime of Coppice is said to prevaiL In the 

 former case the new stock is composed of seedlings, while in the 

 latter it consists principally of shoots from the stool. 



Forests under the first of the two Regimes are worked either by 

 Selection or according to the Natural Method with Thinnings 

 Formerly a tliird method was also in vogue, viz., that known under 

 the denomination of TiRE et Aire, in which the most unbroken 

 regularity was observed in making the exploitations.
