Climate exposure

This is about exposure to a nationwide pressure this habitat type carries — not a verdict on this site's own management.

Coastal

Coastal habitats are exposed to sea-level rise and storm erosion. Where hard sea defences sit behind them, there's nowhere landward to retreat to — a squeeze that keeps compressing the habitat no matter how well it's managed.

Landscape processes: Coastal

Description

Description This site supports the largest single population of the large umbellifer hog's fennel Peucedanum officinale in Britain, a nationally rare plant confined to a few coastal localities in Essex and Kent. The north facing slopes are composed of London Clay and support a tall herb community, dominated by hog's fennel, together with some areas of neutral grassland where the most frequent species are meadow barley Hordeum secalinum, false oat grass Arrhenatherum elatius and red fescue Festuca rubra. Associated herbs include spiny rest-harrow Ononis spinosa, smooth tare Vicia tetrasperma, grass leaved vetchling Lathyrus nissolia and dyer's greenweed Genista tinctoria. The last species is scarce in Kent. Halophytes, such as lesser sea spurrey Spergularia marina, are also present. The fauna of Tankerton Slopes has not been documented although the nationally rare moth Agonopterix putridella, whose larvae feed exclusively on the leaves of hog's fennel, has been recorded from the site.
