Wildlife of Interest

Pingoes are geological features formed immediately after deglaciation some 12,000 to 10,000 years ago. Re-freezing of permafrost groundwater led to blister-like hills each containing a large lens of ice. On warming, the ice melted, leaving depressions surrounded by ramparts. The saucer-shaped depressions filled with water leading to the development of basin-mire communities.

The mires contain several species of Sphagnum Mosses, with species such as insectivorous Round-leaved Sundew, Cranberry, Bogbean and Marsh Cinquefoil.

The dry heathy pastures and wetter hollows contain a mixture of species including Common Valerian, Petty Whin, Dyers Greenweed, Devil's-bit scabious, Heather, Cross-leaved Heath and Marsh pennywort. Gorse and Downy Birch are common.

Birds include typical scrub species such as Long-tailed Tit, Blackcap and Garden Warbler. Willow Warbler and Chiffchaff are common in spring and summer, Reed Bunting and Yellow hammer breed in some years. Butterflies include Orange Tip, Small Pearl-bordered Fritillary, Common Blue, Meadow Brown and Ringlet.
