The number of production exclo- <br />sures established in each vegetation type and control area was determined <br />by techniques described under "Data Collection" above. Table 1 shows the <br />number of production exclosures placed in each vegetation type and con- <br />trol area. <br />Exclosures were left in place throughout the 1979 growing season. All <br />exclosuren were sailed on both affected and control areas during the <br />period August 27 through Septentier 7, 1979.. All production Bangles were <br />mlleck~ lam enough in the day to ensure that the vegetation surface was <br />dry. This precaution ensured tkie accuracy of wet-weight deternunations. <br />Production plots were sampled using a ]mZ welded alumirnan frame quadrat <br />centered within each exclosure. All present-year vegetation growth fal- <br />ling within the lmZ quadrat was clipped using p*+~^;*+g shears (shrubs) <br />and grass scissors (forts and grassesj. All shrubs were clipped near <br />ground level m ensure acairate separation of the present year's growth <br />• in the Lsboramry prior to drying and Weighing. Experience has sham <br />that new growth can be separated accurately only in the~laboramry where <br />envirumrental facmrs such as wind can be controlled. The current year's <br />growth clipped from each protected quadrat was bagged according to major <br />species or life form and properly labeled.
