| Each old field needed from 1 to 3 cards to | ||
| record all the data. Each card is accordingly | ||
| numbered as either: | ||

| 11 | 24 | Blank no punch |
| 12 | 25-27 | Code number of 1st. species encountered: 001-125 |
| See attached list for key. See also thesis pgs. 252-266. | ||
| 13 | 28-31 | Area covered by 1st species: 0025-2500 |
| 1/4 m2 (minimum): 0025 | ||
| 1/2 m2 :0050 | ||

| 14 | 32-34 | Code number of 2nd species encountered: 001-125 |
| 15 | 35-38 | Area covered by 2nd species: 0025-2500 |
Cover data for further species encountered in the 25/ lm2 quadrants sampled in each old field are recorded in this way. If more than 8 species were encountered their data are punched on a second card. however, the data included in columns 1-24 are repeated, the only difference being that column 23 (card number) reads 2 rather than 1. If more than 16 species were encountered their data are punched on a third card. Again the data in columns 1-24 are repeated, the only difference being that column 23 reads 3.
