Based on the mean number of SRS submitted per cohort, the most productive atlassers were recruited before and during the first year of atlassing. Correcting these data (based on 1991, by dividing by the number of years’ atlassing remaining) showed that early recruitment was most productive, with a minor increase from 96-98, when presumably only those with a real interest joined the project. Based on the total number of SRS submitted per cohort, the most productive atlassers were those recruited during the first three years - and prior to - of the project. Corrected data (based on 1991, by dividing by the number of years’ atlassing remaining) show only 1998 to approach the level of atlassing experienced during these years. The number of SRS received per month showed a linear increase during 1991-92 and then experienced an erratic pattern of highs and lows. The low period of 94 was when the scientific officer was in Europe. The high spikes tend to occur after the release of newsletters, Interim Distribution Maps, Field Guides and other communications. In general though, while the pattern fluctuated the peaks show a general increase until 97, followed by a flattening off and a steep final increase. The quarterly running average shows a similar pattern, although the flattening off is during 96 and the increase commences a little earlier in 1999.</p><p>SRS PER MONTH 1400</p><p>1200</p><p>1000</p><p>800 S R S 600</p><p>400</p><p>200</p><p>0 3 4 5 1 2 6 7 8 9 0 3 5 6 0 1 2 2 3 4 4 5 6 7 7 8 8 9 9 0 9 9 9 9 9 9 9 9 9 0 9 9 9 9 9 9 9 9 9 9 9 0 9 9 9 9 9 9 0 ------r r g r g r g g r g g r r g r g r g g c c c c c c c c c c u e p e p u e p u p u e p u e p u e p u e u e p u e u e p A D A A D A A D A A D A A D A A D A A D A A D A A D A A D Date</p>
