Wildlife at Erddig

With 1,200 acres of beautiful parkland, a range of habitats and countryside walks offer a wealth of hidden treasures for all to enjoy.

Erddig’s parkland is remarkably diverse, brimming with grassland, lakes, ponds, rivers, veteran trees and woodland.

The sprawling estate scenery ranges from the peaceful meandering Clywedog river and woodland landscape of Big Wood, to the famous architectural features like the ‘cup and saucer’  and the dramatic escarpment that leads to Wat’s Dyke and the remains of a Norman motte and bailey castle site. 

Veteran trees

Our parkland is one of the best places in the UK for its ancient and notable trees. These include oak, sycamore, beech, sweet chestnut, ash, lime, hornbeam and hawthorn. We have an abundance of ancient oaks, approximately 150 trees at the last count. An ancient tree is a tree which is remarkably old for its species and this can vary dramatically. For example birch are considered ancient at 150 years, oak at 400 years and yew trees an astonishing 800 years.  

Head Ranger, James Stein says:

“1,200 acres is quite a lot of land to care for. But I love how the pulse of nature is always changing throughout the seasons and no two days are the same. We couldn’t do it without our team of dedicated volunteers and community action days.”


The Clywedog River and Black Brook that run through the estate carries many different fish species, as well as eels and water voles. Otters also travel through and visit Erddig, but these elusive creatures remain one of the hardest to spot. Herons can often be seen patrolling the rivers and our rangers often spot dippers playing in the rapids. If you’re lucky, you may even catch a glimpse of our elusive kingfishers!

Lakes and ponds

With over 30 ponds on our estate, Erddig has a very healthy variety of wetland habitats to suit a wide range of aquatic species from dragonflies to swans. Grass snakes like to hang out in these areas too, but don’t worry, they’re totally harmless.
