Factsheets and Guides for Your Visit

Trewalkin Meadow - meadow flora

Trewalkin Meadow is a small, damp, flower-rich meadow at the foot of the Black Mountains between Llangorse and Talgarth. It is how much of Brecknock would have looked 60 years ago, before the habitat was lost due to changes in farming.

What to look out for

The meadow has interest throughout the year with cuckoo flower in the spring; common spotted and early purple orchids in the early summer; globeflower, betony, ragged robin, great burnet and meadowsweet in mid summer and devil’s bit scabious in the early autumn.

The tall trees and high, thick hedges around the site provide valuable feeding and living opportunities for a wide range of insects and birds that rely on the nectar from blossom in spring and summer, and berries and nuts left on uncut hedges in the winter.

The flora’s diversity is maintained by a late summer hay cut and some grazing if dry enough. This regular cropping reduces the dominance of the meadow’s grasses.
