• <br />2.0 METHODS <br />Methods used during [he study were defined during consultation between <br />Perms and Colotado Mined Land Reclamation Division (CMLRD) to address sti- <br />pulation 9 on the permit to mine. The methods were based in part on proce- <br />dures used in vegetation studtes at Chimney Rock Mine during 19$0 and 1982. <br />During consultation to address stipulation 9, modifications of the methods <br />used in previous productivity sampling were made in an attaopt Co achieve <br />sample adequacy. Procedures used during the study are presented below. <br />All sampling during this study vas conducted during July 19-22, 1983. <br />2.1 DEFINITION OF STUDY AND AFFECTED AREA, MAPPING, LOCATION OF SAHPLE <br />POINTS <br />The study area included the undisturbed pirryon-juniper in the Barren <br />Ridge Area and all Revision Area 1 as shown on map 1. Vegetation types on <br />the Vegetation Nap in Chimney Rock Coal's November, 1982 Permit Revision <br />• were transferred to the study area map (Nap 1). Affected area boundaries <br />Including approximately 150 foot buffer zone were determined based on areas <br />identified on the Reclamation Progression Hap (map 13 R 1) dated July 1984. <br />Sample locations were randomly selected in the undisturbed pinyon- <br />juniper type in the Barren Ridge Area and affected area in the Revision 1 <br />Area. A numbered grid vas overlain on the map of the area to be sampled <br />(interval - 100 ft. on the ground) and a table of random numbers vas used <br />to select sample points. Sample locations in the field were de [ermined by <br />pacing from recognizable land marks. Location of sample points Ss shown on <br />riap 1. Acreages of the study and affected areas were determined using <br />standard polar planlmeter techniques. <br />2.2 SELECTION OP REFERENCE AREA <br />A reference area 3 acres in size that vas representative of the spe- <br />cies composition, vegetative cover, herbaceous production, soils, slope, <br />and aspect generally occurring within the piiryon-juniper study area vas <br />• selected. <br />
