Necessity for the conservation of drainage systems as last refugia for threatened damselfly species, Coenagrion ornatum

Popis výsledku v původním jazyce

1. This study analysed the effects of several physiochemical and environmental characteristics of 30 ditch segments in relation to the presence and abundance of C. ornatum. 2. The occurrence of C. ornatum was found to be positively correlated with the diversity of macrophyte vegetation and negatively with shading. Populations of C. ornatum occurred mostly in smaller, well-warmed sections of channel, while the species clearly avoided those sections with gravel or concrete substrates. 3. The ongoing utilisation of channels particularly for drainage accords with the objectives of protecting this species and could substitute for routine conservation management activities. Supplementary effective management should focus on removing overgrowing vegetation, eliminating such negative interventions to the channel as strengthening the stream bed, and encouraging the development of rich vegetation along the watercourses (e.g. by establishing buffers or overflows).
