Submerged forest

[RobArb]

Walking on the beach nr the campsite in Barmouth we came across what looked like rock pools, on closer inspection the "rocks" where soft and squidgy?

 

Turns out they were actually remnants of a forest now submerged that covered the west coast of wales

(not sure if the link will work)

 

you could still see the old tree roots presevred in the peat bed that was only viewable at low tide:thumbup:

 

heres some pics

There is a beach here in the treeless (apart from a couple of plantations)Outer Hebrides that is similar to that. There are tree stumps in peat on the beach which are probably 2-3 meters under water at high tide..

ive been told there are roman villages and old forests under the sea on the east coast and have seen the stumps on low tide i think it was some where around mablethorpe

There is an identical area to this on Broughton Bay, north west tip of the Gower Peninsula. It was caused by an earthquake in the atlantic in 1607. The land dropped by aproximately 1 metre and the resulting tsunami washed away the old natural coastal defences of the sand dunes and permentantly flooded vast tracts of former forest and pasture land. Where the trunks remain exposed you will usually see they all face the same direction, that of direction of wave travel.

It is believed that as many as 6000 people may have died in the Bristol Channel area alone, mostly on the upper tidal stretches of the Severn estuary up as far as Gloucester.

I must get a life!!!

roman villages

 

Robin,

Nice salt water find, great pictures .

At the bottom of Dutch rivers, well preserved oak beams were found, which used to be part of Roman bridges. They were backdated dendrochronologically to 200-300 years before the Romans felled them. All over Europe, the Romans cut old oaks to build bridges, villa's and ships from the wood. They also felled the sacred oaks of the local tribes to demonstrate their ruling power and control.

Once they withdrew from the northwestern European territory, there was no original genetic material of Quercus robur (and Q. petrea) left, so all of our present "indigenous" oaks originate from Turkey or Spain.

In peets and marshes in the eastern parts of The Netherlands, some remnants of old forests have been found, which have to be prepared to preserve them once they are exposed to oxygen.

Thanks Gerrit, don't think anything is being done on the beach were we where on but further down ther coast the peat and trees are being carbon dated and I bet they are Ooooooold..!

 

Never seem anything like it before and glad I have now, just shows how things change over time and to see back in history is amazing!

Rob, nice photos thanks. I should start a new thread so my appols but..

Nooie, interested to hear you're on the Outer Hebrides. I was on Lewis a couple of weeks ago looking a various Coniophora species ( mostly arida) in 19 century buildings. Over the past decade I have visited Lewis looking at structural damage in building timbers. On this last visit I heard a 'legend' that there's no 'dry rot' fungus (Serpula lacrymans) in the buildings on Lewis, and not being able to see why there shouldn’t be any dry rot there, I looked back at our few surveys. Interestingly and unusually I found no positive i.d.s for dry rot (these are done in the field often without FB's). I’ve 25yrs experience of investigating and repairing timber decay in historic buildings and structures in the British Isles and this 'legend' is intriguing. So...nooie do you know of anyone on Lewis or elsewhere in OH you has come across 'dry rot' fungus and especially if they took any photos! Gerrit I would be very interested if you have any comment here.. many thanks Pete Bannister

Pete,

I have posted my comments under Brown and white rot in processed wood.
