Hi xtaaxt
is there any original woods in Euro? you ask.
In western and central Europe the answer is no.
Before humans arrived Europe would have been largely forested. But almost every piece of land in Europe has now been influenced by human activity, either directly (felling trees) or indirectly (grazing by domesticated animals). In the UK we have Ancient woodland, but this is considered to be land continuously wooded since AD1600 (hardly ancient, but the wildlife associated with such sites is very important). Other European countries have similar classifications.
So, although there may be an old forest near you it is likely to have undergone many changes throughout history and will not be original. Even if the forest has been there for centuries, its structure will have changed due to the effects of sheep, cattle, and even deer populations which have been introduced and maintained by humans.
Its only when you go east that you start to find original woods. The forests of eastern Poland are considered as such. They are primaeval almost untouched by human activity.
