Orchids, bird's-eye primrose and other plants thrive in the lime-rich flushes on this reserve.

Highlights

  • In spring curlew, skylark and other birds start to nest
  • Summer is a great time for marsh orchid and bird's-eye primrose
  • Visit towards dusk in autumn to catch the starling roost- see video clip below

Nationally important

Tarn Sike is part of Sunbiggin Tarn and Moors SSSI, which is nationally important for its rich and varied flora and for its breeding birds. Taking its name from the stream that flows flows through the reserve, Tarn Sike has a wide range of habitats.  This is due to the combined effect of the underlying peaty soils and limestone rock.

Wildflowers of heath and lime-rich flushes

Areas of heath with cross-leaved heath, Sphagnum moss and purple moor grass are interspersed with lime-rich flushes where you can find black bog-rush, grass of Parnassus and bird's-eye primrose.  In these flushed areas look out for fragrant, early marsh and northern marsh orchid as well as broad-leaved cottongrass.  You can also find bogbean, round-leaved sundew, butterwort, marsh marigold, meadowsweet and marsh cinquefoil. This is an excellent site for finding some quite uncommon sedges.

Birdlife

Mallard, redshank, curlew, snipe, meadow pipit and skylark have all nested on the nature reserve and are frequently seen during the breeding season. Teal and short-eared owl may be seen in winter.

Invertebrates

In summer you can spot butterflies such as common blue, green veined white and small heath along with emperor and fox moths. From the lime-rich flushes we have records of 15 different species of snail.  We suspect that there is quite a rich invertebrate fauna here but much more work is needed.

Other wildlife

Fox, hare, stoat and short-tailed vole have been seen on the nature reserve.

Keeping it special

In order to maintain the diversity of habitats and species, the nature reserve is grazed between September and March. The effects of this management are monitored via vegetation surveys and fixed-point photography.

Tarn Sike was purchased in 1981 with the help of an anonymous donation.
