National Nature Reserve

What is an NNR?

Deadwood provides an ideal habitat

NNR stands for National Nature Researve and we're proud to say that Dinefwr is the only designated parkland NNR in the whole of Wales because our woodland is home to some of the oldest trees in Britain.

When our trees fall, the deadwood provides an ideal habitat for the Dinefwr wildlife.

Expore th Bogwood Boardwalk

That’s how long this boardwalk is  - at 500 metres. It was first built in 1993 by a group of staff and volunteers. After many years of use it was rebuilt in 2010, with benches added.

It means that you're able to explore this bogwood without wearing waders.

This pond isn't natural

Otters have been spotted at the Millpond

Early 19th-century Dinefwr required a ready source of water, so a dam was built across the small stream. The dam flooded this shallow basin valley and the result was this wonderful pond-life habitat.

Living monuments

We've 300 oak trees that are more than 400 years old.

It's unlikely that you'll find anywhere else in Wales that has so many ancient trees, and is one of the main reasons why Dinefwr is such a special place for wildlife and was awarded National Nature Reserve (NNR) status in 2007.

Dinefwr Park

What a splendid spot to show off our parkland.

This hilltop feature was designed by George and Cecil Rice (second Lord Dynevor) during the 18th century, and promoted by landscape designer Lancelot ‘Capability’ Brown.

What on earth are those bumps?

White Park cattle graze amongst the ant hills in the deer park

They're actually ant hills.

This hillside has one of the largest numbers of Yellow Meadow ant (Lasius flavus) mounds in Wales.

This type of ant rarely comes above ground, but does ‘herd’ aphids underground who feed on the roots of grasses and plants.

Hay-making while the sun shines

There are many hay meadows on the Dinefwr estate. Every year we cut and and bail our own hay and feed it to our cattle during the winter months.

Conservation grazing

We have a dedicated team of staff and volunteers who help maintain our NNR; but our best conservationists are our White Park Cattle.

A very special site

As well as being the only parkland National Nature Reserve in Wales, Dinefwr Park is also a SSSI- Site of Special Scientific Interest. This means we have important wildlife and habitats which must be protected.

    The silent hunter

    A heron uses stealth and speed when hunting and will wait silently in the water for unwary fish.

    Mr Toad says hello

    A toad's skin is rough and warty and it moves a lot slower than a frog so you can really get up close.

    Freshwater dragons

    Dragonflies are four-winged, fast-flying insects with long bodies and enormous eyes.

    The elusive otter

    The elusive otters glide silently through the water and hide in the vegetation until safe to venture out.
