PART II. — MANAGEMENT IN FORCE 



FOKMER MANAGEMENT PLANS 



Art. 1. — Digest of the bases of management. — The State forest of Grande 

 C6te before it became State property belonged to the order of Citeaux, Abbey St. Marie. 



It was originally cut under the selection system, while the yield was regulated by the 

 number of trees in accordance with the former usage. The decree of August 23, 1858, 

 substituted the shelterwood system. The rotation was placed at 150 years and divided 

 into 5 periods of 30 years each, corresponding to 5 periodic blocks on the ground. 



During the first period 1858-1887, the principal felling areas had to be laid out in the 

 first periodic block and in certain compartments of the fourth and fifth periodic blocks 

 with a yield of 2,919 steres or 1,883 m. c. 



All the compartments not subjected to the main fellings were run over by biennial 

 selection fellings to commence with and controlled by volume (310 steres or 200 m. c), 

 but dating from 1864 (decree of June 25) by area and every four years. 



The improvement cuttings were imlimited in volume and the local executive oflScers 

 were free to propose them as they saw fit. 



At the time of the 1884 revision (approved by decree of June 6, 1885) the rotation 

 was 160 years dating from 1858 and divided into 4 periods of 40 years each, corre- 

 sponding to the same number of periodic blocks. 



During the last 14 years of the period (1884-1897), the yield of 1,668 m. c. was secured 

 in the first and fourth periodic blocks. 



Timber of 0.60 m. in circumference (7 inches d. b. h.) cut in the first, second, or 

 fourth periodic blocks (except c.*) was subtracted from the prescribed yield. 



Improvement cuttings in places selection in character, elsewhere thinnings and 

 cleanings were carried out on a cutting cycle of 14 years in the fourth periodic block. 



MANAGEMENT ACTUALLY IN FORCE 



In 1897 (decree of September 3, 1897) the permanent periodic blocks were suppressed 

 and the compartments readjusted in two groups. 



The first group including the compartments to be cut over under regeneration fellings 

 by volume, the second comprising the remaining compartments and the object of the 

 felhngs both for improvement and mere extraction by area. These latter fellings 

 extended also to the first group, but they must not be confounded with the main feUings. 



The yield recruited on the entire area of the forest was fixed at 3,200 m. c. The 

 volume of all conifers 0.80 m. in circumference (10 inches d. b. h.) and above, no matter 

 how reaUzed, on the entire forested area was subtracted from the yield. 



During a period of 16 years, from 1897 to 1912, they carried out: (1) Regeneration 

 fellings in the compartments 1, 2, 3, 4, 5, 7, 8, 9, 12, 13, and 23; (2) improvement cut- 

 tings and extraction on a cycle of 8 years on the entire surface of the forest. 



Art. 2. — Results obtained. — The various fellings have left the forest in the 

 following condition: 



(1) Compartments of the first group, subjected to regeneration fellings (188.69 

 hectares). 



The compartments 1 and 23 may be considered as entirely regenerated; they com- 

 prise poles and young standards over a complete young growth with which there is 

 some old timber which should be cut without delay. On the other hand regeneration 

 must be continued or secured later on in: compartments 2, 3, 4, and 7 which comprise 

 fuU crowned veterans, regular and dense, over advance growth and saplings in groups 

 usually well started: 500 m. c. per hectare on the average of which 41 per cent is timber 

 1.8 m. or more in circumference. Also compartments 8, 12, 13 which comprise rather
