When undertaking an appropriate assessment of impacts at a site, all features of European importance (both primary and non-primary) need to be considered.
Annex I habitats that are a primary reason for selection of this site
|2190 Humid dune slacks|
|Dawlish Warren is a large sand spit with a dune system. The humid dune slacks support a population of the Annex II species 1395 petalwort Petalophyllum ralfsii for which the site is also selected.|
Annex I habitats present as a qualifying feature, but not a primary reason for selection of this site
|2120 "Shifting dunes along the shoreline with Ammophila arenaria (""white dunes"")"|
|2130 "Fixed coastal dunes with herbaceous vegetation (""grey dunes"")" * Priority feature|
Annex II species that are a primary reason for selection of this site
|1395 Petalwort Petalophyllum ralfsii|
|Large populations of petalwort Petalophyllum ralfsii occur in two dune slacks at Dawlish Warren. One of the slacks is on a natural, sandy substrate, and here the population appears to be expanding. In the other slack, petalwort grows on sand overlying an artificial masonry/stone substrate, which receives run-off from an adjacent limestone gravel track. Elsewhere in this slack the sand is more acidic and supports populations of the liverwort Fossombronia incurva. Both slacks are closely grazed by rabbits Oryctolagus cuniculus.|
