CHIE. BANIKHET WOBKING PLAN. 139 



nothing is gained by retaining them once the regeneration below 

 them is as complete as can be expected or is desired. The 

 following marking rules for periodic block I are accordingly 

 prescribed : 



" 1. Where regeneration is absent or deficient, the most suitable First 

 trees for regeneration purposes (with long clean boles and good but ^ e 

 not too branchy crowns) will be retained with an average spacing fellings in. 

 of from 23 to 28 yards according to local requirements and the c ir ' 

 quality of the trees, all the remainder of the overcrop being 

 marked for removal. 



" 2. Where a choice is possible between straight and twisted 

 trees as seed-bearers, the former should always be selected. The 

 damage likely to be done in felling must also be borne in mind. 



:< 3. Large overmature trees, \vhen standing over sufficient 

 established regeneration will be marked. For this purpose 

 " sufficient " must be taken as meaning riot less than plant to every 

 4 square yards approximately, and ' established ' as having a 

 height of not less than 2 feet, and although these definitions cannot 

 be taken rigidly, no large deviation can be permitted. 



" Groups of poles under 3 feet in girth will be retained as part of 

 the new crop when they are of fair to good quality and uniformity, 

 and not less then acre in extent. Such groups 'will be thinned 

 where necessary. 



"Inferior groups of immature trees will be considered as overcrop 

 and dealt with under rule 1 (though a somewhat closer spacing 

 should be given), except when the marking officer is of opinion 

 that, owing to bad ground, he is unlikely even with the subsidiary 

 operations prescribed, to increase the general uniformity by making 

 fellings. In such cases only those trees will be marked which are 

 or are likely to become injurious to the surrounding younger 

 crop. 



" Broad-leaved species may be retained along damp nalas for 

 protection of water-supply, but will otherwise all be marked."
