BioRisk 5: 155–173. doi: 10.3897/biorisk.5.847 Abstract Th e trends of 60 Dutch dragonfl y species were calculated for three diff erent periods (1980–1993, 1994– 1998 and 1999–2003). Comparing period 1 and period 3 shows that 39 of these species have increased, 16 have remained stable and 5 have decreased. Th ese results show a revival of the Dutch dragonfl y fauna, after decades of ongoing decline. Th e species were categorized in diff erent species groups: species with a southern distribution range, species with a northern distribution range, species of running waters, species of fenlands and species of mesotrophic lakes and bogs.
