9 22 Blank no punch
10 23 Card number
Each old field needed from 1 to 3 cards to
record all the data. Each card is accordingly
numbered as either:
1
2
3
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
3/4 m2: 0075
1 m2: 0100

Up to

25 m2 (Maximum): 2500
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.
