Mid Cornwall Moors SSSI is a Site of Special Scientific Interest (SSSI) in Cornwall, United Kingdom which was created in 2017, expanding on several former SSSIs. The site covers 1,653.02 hectares (16.5302 km²; 6.3823 sq mi)

The site is home to populations of marsh fritillary and willow tit, species which .^[1]

History

The previous SSSIs which were merged into Mid Cornwall Moors SSSI were Goss and Tregoss Moors, Red Moor, Retire Common, Breney Common, Belowda Beacon and Tregonetha and Belowda Downs.^[2]

There were eight objections to the proposed designation.^[3] The new SSSI was came into effect on 23 February 2017,^[4] and was confirmed four months later.

Vascular plants

Several nationally rare and scare plant species have been recorded within the site.

Nationally rare species present include Cornish eyebright (Euphrasia vigursii) and coral-necklace (Illecebrum verticillatum).

Nationally scarce species include:

Yellow centaury (Cicendia filiformis)
Wavy St John's-wort (Hypericum undulatum)
Marsh clubmoss (Lycopodiella inundata)
Round-leaved mint (Mentha suaveolens)
Pillwort (Pilularia globulifera)

Three-lobed crowfoot (Ranunculus tripartitus)
Cornish moneywort (Sibthorpia europaea)
Marsh fern (Thelypteris palustris)
Pale dog-violet (Viola lactea)
Marsh violet subspecies (Viola palustris subsp. juressi)

Invertebrates

The site is reported to be one of the last habitats for the pond mud snail (Omphiscola glabra) in Cornwall.^[5] The species used to be "fairly widespread" in Cornwall but has only been found in four sites since 2000.^[5]

62% of marsh fritillary (Euphydryas aurinia) populations in Cornwall went extinct between 1990 and 2000 and the mid-Cornwall Moors are one of its "core geographical areas" in the region and the species' "most westerly stronghold".^[6]
