Dutch Butterfly ConservationDutch Butterfly Conservation

Dutch Butterfly Conservation is a national organisation that bundles knowledge about butterflies and dragonflies. It is committed to the preservation and recovery of butterflies and dragonflies in The Netherlands and Europe. Together with Dutch Butterfly Conservation, Sempergreen has done research on the functional contribution of a green roof to the biodiversity of urban areas. Based on the findings of that research, the Biodiversity Package was developed; to add nesting grounds, shelter and food to a Sedum roof. This further increases its ecological value. Another product that was collaboratively developed is the Bees & Butterflies Blanket. This vegetation blanket creates a green roof with an abundant mixture of host and nectar plants, which is very attractive to bees and butterflies.
