Although mainly a conifer plantation for 80 years, there were some parts of Coed Craig Ruperra where the ancient woodland remained. These form a seed bed for the future regeneration of the tree and plant species of the ancient woodland.

Without the dense conifer cover, these species will reappear and flourish, and the smothering bracken which erupted after the clearfelling of the 1990s, will gradually subside.

The Trust has augmented the natural regeneration of the site by replanting with native broad leaf trees.

Habitats favourable to the native wildlife species, which had disappeared as the conifers grew thicker and taller, will then attract back the animals and birds of former times.
