AO BULLETIN 367, U. S. DEPARTMENT OF AGRICULTURE. 
(4) Records of animal-days’ feed consumed for a period of five 
years on about 16 per cent of the best part of the reserve show exactly 
what this land can do under a certain kind of management. The 
type of management used tends to make the carrying capacity for 
this area appear high. ‘The pastured area naturally has the highest 
carrying capacity of any part of the reserve. The area has probably 
been slightly overstocked recently. All three of these factors tend 
to increase the apparent carrying capacity of the area under stock. 
The figure representing average carrying capacity for 74 sections 
(one-eighth of the whole reserve) which have been stocked with 
cattle is 14.1 acres per head per year, or 45+ head per section. This 
carrying capacity, for the reasons stated, is considerably above that 
for the whole range. Just how much too high it is would be very 
hard to tell. Figures obtained on one of the pastures show that 
stocking at the average rate of 58 acres per head per year, or 11 
head per section, is considerably below the limit of maintenance 
capacity, since the pasture so stocked is now not noticeably different 
in condition from adjacent land which has had no stock on it for 
il years. . 
Miscellaneous data.——Miscellaneous notes on the effects of fire, the 
effect of protection on the minor relief features of the area, some 
results of seed sowing, the results of a small amount of sheep grazing, 
etc., are added, and a few suggestions as to the character of future 
work are made.
