Heritage Lottery funding helped the Trust to expand and a bequest of £1,000,000 in 2003 resulted in the appointment of a Reserves Officer.
[3] The most visited of the reserves is at Pwll-y-Wrach ("Witches' Pool", near Talgarth; the site is 17.5 hectares in area, most of which is woodland.
[5] The wildlife in this area includes bluebells, woodruff, orchids, herb paris, toothwort, dormice and dippers (which frequent the waterfall).
The grasslands of this former sports field encourage marsh fritillary, meadow brown and gatekeeper butterflies.
