Hunting for ferns

On 26 September I took two of our leading fern experts, Paul Ripley (left) and Pat Acock from the British Pteridological Society to the fernier parts of the woods and learnt a great deal myself about how to distinguish one fern from another.

So far we have recorded 14 fern species and 2 horsetails (also pteridophytes).  These include western polypody (Polypodium interjectum); common polypody (Polypodium vulgare); bracken (Pteridium aquilinum); hart's-tongue fern (Asplenium scolopendrium); lady fern (Athyrium filix-femina); hard shield fern (Polystichum aculeatum); soft shield fern (Polystichum setiferum); scaly male fern (Dryopteris affinis); Borrer's male fern (Dryopteris borreri); narrow buckler fern (Dryopteris carthusiana); broad buckler fern (Dryopteris dilatata); male fern (Dryopteris filix-mas); hard fern (Blechnum spicant); field horsetail (Equisetum arvense) and great horsetail (Equisetum telmateia).

Hay-scented buckler fern (Dryopteris aemula) has been recorded in the past, but has not been seen recently, while maidenhair spleenwort (Asplenium trichomanes ssp. quadrivalens) grows plentifully on the bridge in Reservoir Lane opposite the entrance to Rafters Wood just outside the Woodland Trust boundary (see below).

Some of the Dryopteris species are quite a challenge, even for the experts.  The male fern, the scaly male fern and Borrer's male fern are not easy to tell apart, have many different forms and often produce hybrids.  On our field trip we found, for example, one hybrid male fern (Dryopteris x complexa) by the public footpath above Powdermill Stream.  The red-stemmed form of the lady fern also occurs here and there.

Several of the ferns grow in large numbers in Brede High Woods, but are not all that common in South East England, preferring the damp, sheltered, wooded valleys and gills of the High Weald.

Introduction to the blog

Brede High Woods is a 262 hectare (648 acre) Woodland Trust property in the parishes of Brede Sedlescombe and Ewhurst Green to the north of Hastings in East Sussex, UK. It is a complex of wildlife rich ancient woodland and plantation woodland, with some grassland and heath. There is also considerable historic interest from the former farms, and activities associated with the powder mill and ironworks that once operated nearby. There is open public access and details of the site are published at http://www.wt-woods.org.uk/bredehighwoods

I created this weblog in 2008 with the intention of bringing news of the woods to anyone who is interested. I work closely with the Woodland Trust and am an ecologist by profession, but this weblog is entirely my responsibility, my main qualification being that I live close to the woods and have walked them regularly since the late 1950s.
