Southern damselfly  (Coenagrion mercuriale)

Since 1960 the UK range of this species has decreased by 30% (4). Reasons for this decline include a decrease in grazing levels resulting in a loss of the open habitat needed at breeding sites. Water drainage, dredging and nutrient enrichment from agricultural run-off are also likely to have impacted on this species (3).

The UK population of the southern damselfly is of international importance. The species was highlighted as a priority for conservation by the UK Biodiversity Action Plan (UK BAP). The Species Action Plan has three main aims: to ensure that all UK populations are in favourable condition, to maintain the 1995 UK range preventing further loss of sites in England and Wales, and to increase the 1995 range by encouraging re-establishment of 5 former sites in 2005 (4). A steering group was formed to co-ordinate the conservation of this species; this includes the Environment Agency, The Wildlife Trusts, English Nature, Countryside Council for Wales, the British Dragonfly Society and Liverpool University (3).
