Peak Ridge

The Peak Ridge is significant not just for its size, but for the complexity of its habitats. For many habitat types, more than half of the species recorded in the entire Sidmouth survey area are found here.

The Influence of Heath and Soil

The high-altitude ridge is dominated by Upper Greensand soils, which are highly acidic. This has created a sanctuary for specialised species:

• Acidic Specialists: 100% of the survey area's Acid Grassland, Wet Dwarf Shrub Heath, and Conifer Plantation species are found within this cluster.

• Dry Shrub Heath: Nearly all (96.6%) of the area's dry shrub heath species reside here.

• Historical Preservation: Because of the difficult terrain and acidic soil, much of this land escaped intensive agricultural use, preserving its natural state.

Woodlands and Water

While heathland dominates the heights, the network also supports:

• Broadleaved Woodlands: Nearly 75% of the woodland plant species from the entire survey are found in areas like Peak Wood, Harpford Wood, and Core Hill Wood.

• Hidden Streams: Despite the ridge's height, small streams and accumulation points allow water margin vegetation to thrive.
