National Nature Reserve
What is an NNR?
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.
Five football pitches
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
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.
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.
Master of all you can see
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?
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.
What animals might you see at Dinefwr?
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.
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.
