Areas to be affected by mining activities were <br />delineated on aerial photographs (1" = 400'). Because of the small areal <br />etct~t of the two vegetation types subjected to quantitative sailing on <br />the affected area, a systenatic tectuuque was used for san~le site loca- <br />tion. This entailed estalzlistmm~t of production exclosures aid cover quad- <br />rats at predetermined paced intervals within the type in a manner m <br />ensure complete coverage of the type. The diirensions of each such type <br />were carefully measured on the topographic Lase map. Sanq~le points were ,~ <br />then e3ually spaced within the type det;.+ motion on the map. Farb point sys- <br />temstically located in this manner was placed in the field by pacing first <br />from a reoogiuzable landmazk to locate the first point and then from located <br />points to place the rams;*rtor of sample locations. The control sites <br />were sled in the same fashion. Fade located sample point was marke3 <br />with a Mooderi stake which identified the sai~le number and vegetation type. <br />All points ce>.,; flagged above the vegetation to allow easy relocation. <br />One rover quadrat and one production exclosure were situated at each <br />• - sanq>le point. Nver quadrats were paced in a wnsistent manner with ore <br />corner touclting-the south side of the sample location stake. Production <br />exclosures arse situated Sm north of each samq~le location stake. This <br />tectuiique ensured the unbiased positioning of both rover quadrats and pro- <br />duction exclosures around the san~le point. . <br />Data Collection. Cover was estimated using a 20x5Oan (1/l0m2) steel frame <br />quadrat at each sample point in each vegetation type. A total of 159 <br />quadrats wrie sampled for rover during this study as shown in Table 1. <br />This sanple size and all production and rover sample sizes were deter- <br />mined on the basis of several criteria: <br />1. Wyani.ri9 DF7) Guideline $2 (March, 1979) suggested that sample size be <br />established on the basis of pre-sample data.
