The forest of Trigiodo-Vroulidia is an important ecosystem centred on an oak forest, this occupies the inner valley of a mountain massif at Anogeia, which borders the Zominthos area.
The trees growing here have attained a great age: the trunk diameters are more than a metre wide, and they grow to 15 m high. They grow so tall that they form a proper bio-system of a forest with many shrubby types to fill out the ranks of vegetation.
With them are other species typical for such an environment – holm oak, mock-privet, maple, cypress, pine, plane, pear and others.
The importance of the forest is due to the fact that the oaks have grown beyond their usual body shape and dimension, acquiring the characteristics and a size different from what we are used to see in Greece. The chances are that at some time in the past the normal adverse factors (people, goats etc) were removed – so that the oak bush managed to develop in the manner we see today.
On the slopes round and about are scattered mitata.
