<br />6.0 OLD FIELD AND CULTIVATED FIELD <br />6.1 INTRODUCTION <br />Pursuant to a verbal agreement with CMLR staff, quantitative vege- <br />tation sampling in 1982 was confined to a reseeded grassland community <br />told field) and a cultivated field proposed for disturbance. <br />This section presents and discusses the quantitative data for the <br />old field vegetation mapping unit and provides information on crop <br />production in the cultivated field. <br />6.2 METHODS <br />6.2.1 Experimental Design <br />Cover, production, and woody plant density data were recorded <br />for the old field vegetation type. A grid scaled to 50 ft by 50 ft was <br />established on the vegetation map in the affected area. Pairs of random <br />numbers were used as Cartesian coordinates to locate sample points. <br />Sample points were located in the field by use of a USGS map and pacing <br />where necessary. <br />• 6.2.2 Vegetation Type Delineation and Mapping <br />See Section 2.2. <br />6.2.3 Collection and Identification of Plant Species <br />See Section 2. 3. <br />6.2.4 Cover, Production, and Woody Plant Density Sampling <br />See Sections 2.5, 2.6, and 2.7. <br />6.2.5 Sample Adequacy <br />See Section 2.8. <br />6.2.6 Species Diversity <br />See Section 2.10. <br />6.3 RESULTS AND DISCUSSION <br />6.3.1 Old Field <br />• The old field community consists of the species listed in <br />Table 32.
