The reserve is of particular importance for its lowland heathland habitats and the variety of rare and specialist wildlife, including Cornish heath.

Jointly owned with Cornwall Birdwatching Society, Middle Amble Marsh has a mosaic of fen and wet grassland which benefits a wealth of wildlife that uses the site.

The reserve consists of heathland, small areas of pasture, and open water, which was created by flooding the disused clay pits.
