Hunter success during the opening weekend of the hunting season in 1975 
«s expected to be greater than in 1974. As reported in September (MWRL 18(9) 
Table 1 ), the numbers of broods observed per 100 miles of driving in Auqust 
975 revealed substantial increases over the numbers of broods observed in 
(FCMU)° r ° C 6 ' ey Study Area (SSA) and the Ford County Management Unit 
H unt er success during the opening weekend may be additionally improved 
by enhanced accessibility to birds as row crops harvesting and fall pawing 
occastonaf" T'* thus “nitrating birds ^permanent cover and 
“"harvested corn and soybean fields. On the SSA and FCHU, almost 
90 percent of the soybean harvest and approximately 50 percent of the corn 
JhaTave^a „ been com h ,ete ^ by 14 October 1957. Weather permitting, a larger 
Jh! nn«t Proport,on of row crop fields will be harvested and plowed by 
the onset of the pheasant season on 8 November. Y
