Home to a secret world of plants and species

Although it’s easy to think of the National Park as mountainous and rocky, it has around 36,400 hectares of woodland, which is 17% of its total area.

These forests are rich in broadleaf, conifer and mixed trees and are teeming with wildlife, rare creatures, plants and fungi of all kinds.

Native trees
Many native trees and plants can be found in the forests of Eryri, including oak, ash, beech, sycamore, birch, cherry, hazel, alder, rowan, hawthorn and holly. Some of our native trees have suffered from diseases such as Dutch Elm Disease. One of the most severe diseases at present is Ash Dieback Disease. According to the Woodland Trust, this disease could destroy up to 80% of British trees

The importance of forests

The forests of Eryri play a big part in tackling some of the biggest challenges facing the National Park. They even play a significant role in the culture and mythology of the area.

A valuable asset
Forests are a valuable natural asset. They protect from flooding, improve our air quality and provide shelter for animals.
Stories, folklore and mythology
Our beautiful, natural woodlands are some of the greatest treasures of rural Wales. They are a backdrop to many of Eryri's stories, folklore and mythology.
High environmental standard
The National Park Authority owns several woodlands, which are managed to the highest possible environmental standard.
Protecting deciduous woodlands
The National Park Authority protects, enhances and extends native deciduous woodlands and their biodiversity by providing advice, assistance and grants.
Coniferous woodlands
Although coniferous woodlands are of lower ecological value, they still play an important role in biodiversity, such as at Coed y Brenin and Coed Gwydir.
A habitat for rare plants and species
Eryri's woodlands are important habitats for rare plants and species such as fungi and mosses.
