<br />f <br />~• from a table oP random numbers with 99 as the greatest <br />possible number. The field operator then paced along the <br />~. <br />r y axis (north) the number indicated by the first random <br />~~ number, turned 90 degrees and paced in a direction parallel <br />r to the x axis the number indicated by the second random <br />number. A quadrat was positioned at this point and estimates <br />r <br />made. <br />r Exclosures erected in the spring of 1981 were rectangular <br />_. in shape, standing approximately two feet high and having <br />- s rectangular base approximately two Peet wide by Pour Yeet <br />~- long. 'fielded wire (12.5 gauge, 2 x 4 inch mesh) was cut for <br />construction oP the exclosure and was secured at each corner <br />__ with No. 9 baling wire. Two or more 18-inch stakes (3/S inch <br />;_, rebar) were driven in the ground at the base oP two or more <br />- sides of the exclosure to help hold the wire against the <br />ground. <br />Cover was estimated from a one-meter squared quadrat <br />_ placed within at the exclosure site. A rectangular quadrat <br />_ (0.5 meters squared) was placed in the exclosure and was <br />_ used for production clipping of the understory species. Tree <br />and shrub density data were also collected at each of these <br />random points. <br />By using the above procedures, all areas had an equal <br />_ chance of being sampled. Random sampling proceeded until <br />., <br />-6- <br />
