A favorite walk

Near where we live, there is a wonderful valley, which is rich with wildlife and just a little bit scenic too.  The Bybrook river runs through it, where dippers and kingfishers are regularly seen.   Native crayfish can still be found in their rocky hideaways, and I understand that lampreys are also present.  Water crow-foot is quite common and there is a healthy insect population, including mayflies (but also horseflies!).


The valley sides are a mixture of broadleaved woodland and rich unimproved limestone grassland or less interesting grassland, whilst the flat bottoms also have areas of meadow flowers in some places, where the cattle have not reached.

Last sunny Sunday we paid a visit - here are some of the pictures.

The damselflies were fighting for territory, displaying to the females and for some lucky individuals also mating...

This orchid is a sure sign that mid summer is upon us; its only grows on alkaline soils such as those on chalk or limestone

The aptly named fragrant orchid is a little stunner

 Dyer's green weed

This plant was once used as source of yellow dye for the cloth industry - an uncommon flower nowadays

 A boletus fungus - there were quite of few of the ascomycetes growing in the grassland

North Devon - more than just cream teas (Part #2)

As well as exciting rocky shores north Devon also plays host to huge beaches, backed by Sahara scale sand-dunes (...well it feels like the Sarhara when the sun beats down!).

Its all go on the beach - more relaxing on the headland...

The sand dunes are a dynamic environment where specialist and adaptable plants find a foothold.

The flora is very rich and where the rabbits graze is on quite a small scale.  The dunes therefore rages from bare sand, to beds of orchids and other species, to tall scrub....its a botanist's dream.  Here are some of the plants and insects that are on the more charismatic side:

North Devon - more than just cream teas (Part #1)

North Devon is wonderful - rolling hills and deep valleys with lush woodlands, sunken lanes lined with foxgloves and the beautiful coast with cliffs and sand-dunes in equal measure  - what's not to like.

As you walk along the coast (in this case around Morthoe - which incidentally has a fab camp site!), the quiet fields often support permanent pasture grazed by sheep and hay meadows.

 Local grazers

The sheep don't eat the foxgloves (probably due to the digitoxin which may kill them) so these stand bolt upright in splendid isolation.  They create quite a picture.

Foxgloves and windblown tree

Paths weave their way down to the beach and seashore, providing rich corridors for wildlife.  On this occasion there were dozens of speckled wood butterflies vying for a territory.

Many beaches are large expanses of flat sand with only the odd struggling jellyfish washed up.  However there are also many small inlets with rockpools and rough beaches - these are what the real wildlife enthusiast heads for.

Steps down to the beach

The cliffs present one of the very few natural habitats in Britain.  Their unstable nature, and exposure to salt and winds, means that in many areas only the hardy maritime specialist plants thrive, such as the pink thrift, the blue sheep's bit and sea plantain.  These are often joined by vetches, such as the yellow flowered kidney vetch.

On areas of almost bare rock another set of plants such as hawkbits and sedum species grow.

Of course the seashore also supports many thrilling breeding birds such a fulmars, gulls and this oyster-catcher, with its shrill, piping alarm call.


Rock pipit

Rock pipits, jackdaws and the odd raven can also be seen.  If you are really lucky,  you may see peregrine falcons swooping past as they chase after doves or other birds.  I saw one with food in its talons.

Down on the beach, the where the tide has receded and left pools behind, there are often rich pickings if you spend the time looking.  Small fish called Blennies are common inhabitants of the larger pools, as are sea anemones and shrimps.  Of course there is a myriad of shellfish such as limpets, cockles, winkles and periwhinkles.

The layers of seaweed hanging from the rocks, or those still immersed in the pools, can be easily overlooked. However many are very colourful and have an interesting structure, such as the fucus species with its bladders to keep it upright when in the water.

Under every piece of seaweed there are sand hoppers and under almost every sizeable rock there seems to be a crab.

This is just a taster of the rich diversity that our wonderful coast offers  - so try to get down there at least once this season.
