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.

Description

Description How Hill Track provides suitable conditions for seven rare and notable plants, all regarded as Breckland specialities. These plants are all confined to the strip of neutral grassland between the shelter belt and the adjoining arable field. This area was once the headland of the field and as such was only partially disturbed by cultivation. The track has been in existence for many years and the area was fenced off in 1980. Perennial knawel Scleranthus perennis var prostratus is confined to Breckland and is found at How Hill Track on the semi open, low sward of the track itself where it is freed from competition by taller plants. The remaining species, small Alison Alyssum alyssoides, Spanish catchfly Silene otites, Breckland speedwell Veronica praecox purple stem cat's tail Phleum phleoides, small medick Medicago minima, sickle medick Medicago sativa subsp. falcata, are all found in the longer grass of the verge. The typical associates of these varieties found on How Hill Track include, thymeleaved sandwort Arenaria serpyllifolia, purple milk vetch Astragalus danicus, lady's bedstraw Galium verum, bird's foot trefoil Lotus corniculatus, ribwort plantain Plantago lanceolata, biting stonecrop Sedum acre, yarrow Achillea millefolium, ragwort Senecio jacobaea, bindweed Convolvulus arvensis, crested hair grass Koeleria macrantha, common bent grass Agrostis capillaris, perennial rye grass Lolium perenne, cock's foot Dactylis glomerata and barren brome Anisantha sterilis.
