Ancient forests once covered Ireland.  Huge oaks, yew and pine that grew and died since the last ice age some 10,000 years ago.  The farming techniques of our stone age farmers along with dramatic changes in climate eventually killed much of this original tree cover.

The term bog oak is often used to describe all types of bog wood.

Some roots and even trunks were buried in the wet marshy land which was slowly developing into our modern bog land.  Much of the wood lay undisturbed for up to 7,000 years, preserved in its enclosed environment, hidden from our view.
