SUMMARY<br />
Coenagrion pulchellum first appeared <strong>in</strong> the area <strong>in</strong> 1960. This led to a marked reduction of Coenagrion.puella on the sand<br />
pools. In re<strong>in</strong>vestigat<strong>in</strong>g the area <strong>in</strong> 1974 van Noordwijk found that the numbers of Coenagrion puella had recovered and the<br />
two species of Coenagrion were fly<strong>in</strong>g more nearly the same time.<br />
Based on the records <strong>in</strong> the period 1996-2007 Coenagrion pulchellum has fully disappeared from its former habitats. Overall<br />
this species has shown a significant <strong>de</strong>cl<strong>in</strong>e <strong>in</strong> Flan<strong>de</strong>rs due to loss of its biotope. This could be the case <strong>in</strong> our reserve, seen<br />
the <strong>in</strong>tensive fish<strong>in</strong>g activity s<strong>in</strong>ce the 70’s, but it might as well be fully outcompeted by Coenagrion puella. In may 2000 en<br />
2004 some specimen were seen throughout the area. S<strong>in</strong>ce no settl<strong>in</strong>g followed they can be consi<strong>de</strong>red as dwell<strong>in</strong>g specimen.<br />
