arosa, \/hat is thio comparison? How ccn it be described 

 and standardized? 



In the past Y;O have submitted grazing reports at the 

 end of every reason shov/inf* the crrryinr; capacity of each 

 rnn^c, estimated by different systems, rod out from the 

 v:nt of stock aotut'.lly grazed, condition of range after 

 -rr.zed, and comparison with other well knov-n ranges. 



The average rrngor can estimate the carrying capacity 

 of u range very closely, but vhon ho is rskod ho-.? ho did it or 

 how anyone else should be instruct' to do the srmo work, he 

 thinks u . hilo and -ivos it up. Some sr.y that grazing rcocn- 

 naiscanco ccnnot be done r.ccuratoly until the forage value uf 

 oach plant is known. Others any it cnnnot bo dne by anyone 

 who has not had experience in stock grazing. 



Admitting thc.t the kno'in value of each plant would be 

 of sor.e value, it ie not absolutely necrsoary to have this 

 Imowlod^e for rrnrro reconneiseance vhen several different 

 plants nre considered torcthor as r. type. It is also a 

 demonstrated fact the t come Of the bent grazing reconnaissance 

 is done by nen who novor herded sheep for a livln nr . 



After considering the rifforont clfnres cf fore^e on 

 the Tf.hue Forest no decided to standrrdize our reports by 

 dividing fort je into r few well known types. The types 

 adopted 'rrero ns rcllov/s: ^ood 3rowco , Modiura Irowee, Good 

 Graeo, . : lediun Grass, lleado^ and Sn^o Brush. The next etop 

 was to make o ^razinr legend with a color for oach type, and 

 wr.ste brush and barren creas ?.'hero there is little or no feed. 

 Thic -ives a stanc'r.rd method of raap;in.^ ranges and a chance to 

 orlimate the area of or.oh type in a rrn^e. Then by corrrprrison, 

 the keynote of r:mp:o reconnaissance, we can ta!:e the kno^n 

 carryinr capacity of kno"n sections of a type rnd rscertain 

 \vhat thet type should crrry vn each cootion t in untried rrn~es. 



If we have no idea of the carrying capacity of rny 

 particular type it is easy to hr.ve a section grazed v/ith a 

 given pnount of i took rnd r.ocortain the time that it tr.':oe to 

 feed it. Unc'or the old system v^e cctirrate " that n section 

 would carry a certain nunber oi' stock Tor t'-e seocon. Undor 

 the noxv i;ytera we estimate how lon.^ a section 'rill carry an 

 avorr. -o band of stock. Under the old system v/e mi^ht ask 

 every stocknrn no meet how many stock a section v xuld crrry 

 for a socson r.nd r-l^cys receive the sf.ie reply "I d&n't loiow".
