Cae Lynden Nature Reserve

Cae Lynden nature reserve

Cwm Wanderers once played football on this site. It is now a nature reserve of wet tussocky grassland known as Rhos pasture. It is home to the rare marsh fritillary butterfly.


What to look out for:

The marsh fritillary butterfly breeds at Cae Lynden - this is a larval web made by the caterpillars

Heath spotted orchids grow in the rhos pastureIn spring look for the bright yellow flash of the brimstone butterfly and in summer the grassland is full of ringlet, meadow brown and gatekeeper butterflies. The marsh fritillary flies in June laying eggs on devil’s bit scabious leaves. In August & September its caterpillars feed on devil's bit scabious within their larval webs amongst mollinia tussocks. Late summer wildflower displays of purple flowering devil's bit scabious and red ragged robin. Woodland birds in the oak woodland and snipe and woodcock in winter.
