i ,: - <br /> <br /> One of the parameters to be measured is cover and this <br /> will be done by using the l ine intercept method. This method <br />t was chosen b ecause it is a technique that is used in cover <br /> studies done in grasslands, shrubland and forests. The sam- <br />1 <br /> pling method used should be conducive to sampling in both com- <br />' munities and, it is apparent that the line intercept method <br /> satisfies this r equirement. <br />t Preliminary sampling will involve obtaining cover data <br /> from twenty tran sects. The transects will be randomly located <br /> i <br />id <br />b f <br />h <br />l Th <br />id <br />b <br />l <br />d <br /> ng a gr <br />y us ay o <br />t <br />e area to <br />over e samp <br />e <br />e gr <br />. <br /> lines will be .5 inches apart and a nu mber will be assigned to <br /> the intersection of the coordinates. A random number table <br />' will be used to determine the starting point for each of the <br /> transects. After the starting point is selected, a number be- <br />' 0-360 <br />ill b l <br />d <br />l <br />t <br />d dir <br />tion <br />d <br />i <br />th <br />t <br />t <br /> w <br />tween <br />e y se <br />ran <br />om <br />ec <br />e o <br />e <br />erm <br />ne <br />e <br />ec <br />' in which the transec t will be laid ou t. The transect will be <br /> 15 meters in length and the portion o f the transect intercepted <br />' by each species will be recorded and used to develop the percent <br /> cover for herbaceous vegetation; bare ground and litter will al- <br />' <br /> so be recorded. <br />' Once the preliminary cover information is obtained from <br />the twenty transects a mean and variance for the characteristic <br />' will be calculated. This information will be used in the Snedecor- <br />Cochren equation to determine if an adequate number of samples <br />have been taken. The equation is as follows: <br /> <br /> <br />
