~. <br />~~ I-3.3 Production <br />r <br />f <br />• The big sagebrush type had the highest understory <br />production (637.5 lbs/acre) on the study areas Yollowed <br />by the pinyon-juniper type (292.5 lbs/acre) (Table 8). The <br />mountain shrub type had the third highest production (257.8 <br />_ lbs/acre) and mountain shrub - north facing slope type had <br />'the lowest production (91.0 lbs/acre) on the study areas. <br />Total production for the two references areas averaged 211.5 <br />• lbs/acre on mountain shrub and 87.4 lbs/acre on <br />pinyon-juniper. <br />_. Perennial grass and forb species comprised the majority <br />of the production. for all vegetation types except big <br />• sagebrush. Production of grasses snd (orbs ranged from 42~ <br />of the total on the big sagebrush type to 82~ on the mountain <br />shrub type. On the study areas, grasslike, half-shrubs and <br />-- annuals comprised less than 45~ for all types except big <br />- sagebrush where annuals (particularly grasses) comprised <br />over half of the total production. <br />_ Table 9 summari2es production data in lbs/acre, <br />_ kg/hectare and g/m2 for the study areas. Means, standard <br />deviations, number of samples taken and number of samples <br />- needed to meet suggested sample adequacy are listed in Tabls <br />10. Sample adequacy was attained for all types and the <br />reference areas. <br />~~. <br />- 24 - <br />
