ORIGINAL WORKING PLAN DATA

It win be calculated anew with the 1911 valuations as a basis, and after taking account 

 of the state of the stands; the annual growth of 7.3 m. c. (which) is a growth per cent 

 of 2 for the period 1883-1911. Under these conditions the State forest of Grande 

 Cote will be treated as regular high forest in a single working group with a rotation of 

 150 years. 



The shelterwood system will continue in force, but with the following modification 

 (see "Regulation," p. 239): 



The permanent periodic blocks will remain void but the compartments will be divided 

 into three groups: (a) Compartments to be regenerated; (6) those compartments 

 which according to aU probability will be ready for regeneration after those of the 

 first group; (c) the remaining compartments of the forest. 



The compartments will continue to be designated from the N. E. to the S. W.; in 

 the course of time by Arabic numerals. On the map the compartments of the first group 

 wiU be shown by blue; those of the second group by yellow; while those of the third 

 group will not be colored at all. 



Art. 2. — Dividing the forest into compartments. — The former division into 

 compartments has been preserved when it is suitable on the ground: it has only been 

 modified as to the former compartments 23 and 24, each of which have been cut in two 

 to form the new compartments 23, 24, 25, 26. In order to establish the special felling 

 plan the compartments have been divided into three groups. In the first have been 

 placed compartments 2, 3, 4, 7, 8, 12, 13 which contain the most mature timber, whose 

 regeneration should be carried out during the period for exploitation and which there- 

 fore wiU be cut for regeneration. The second group includes compartments 4, 9, 10, 

 14, 15, 19, 22 which apparently will come in turn to be regenerated after those of the 

 first group. The third group will be formed of the remaining compartments 1, 6, 11, 

 16, 17, 18, 20, 21, 23, 25, 26, 27; these last two groups will be run over by improve- 

 ment and extraction feUings. Consequently the following general felling schedule is 

 proposed:
