The replanting of 12,000 trees after the spread of a disease which affects larch has led to the “rebirth” of a forest visitor centre, said managers.
They have replaced 10 hectares (25 acres) of larch felled to slow the spread of Phytophthora ramorum at Bwlch Nant yr Arian near Aberystwyth.
The disease has infected over six million trees in Wales since 2010.
Natural Resources Wales (NRW) said native trees such as birch, hawthorn and blackthorn had been planted.
Gareth Owen, visitor centre manager for NRW, said: “The whole site has come on fantastically well since the replanting.
“The felling provided us with an unexpected opportunity to create better, more resilient forests for the future by replanting more diverse native trees.”
The site’s red kit population has also continued to thrive.
