<br />existed to enable the establishment of an Oak control area. All of the <br />control areas were at least two acres in size. <br />Production data were obtained by randomly locating 0.5 M x 1.0 M <br />quadrats within the control area. Harvesting, drying and weighing <br />procedures were the same as those employed in the affected areas. <br />Cover data were obtained using the same procedure as for the <br />affected area, with the exception that the transects were located <br />within the control area. <br />Shrub and Tree Density Measurements <br />Stands of shrubs and trees were sampled in the vicinity of <br />exclosures using the angle-order method (Strickler and Sterns 1962). <br />Sample points were located at 10-meter intervals along randomly located <br />100-meter transects. Data collected included distance from sampling <br />points to the third nearest shrub or tree, species indentification, <br />diameter at breast height (for trees) and shrub and tree height. <br />Sample Adequacy <br />Adequacy was calculated by using the following formula, with the <br />exception that a two-stage sampling technique was utilized for <br />determining variance (see Cochran 1977, Chapter 10) for those <br />vegetation types which were sampled by the two-stage <br />2.4-10a August 18, 2005 <br />
