Biodiversity, Landscape, and Conservation in Churston, South Devon

Churston, located in South Devon between the urban centres of Paignton and Brixham, occupies a distinctive ecological position within the English Riviera landscape. Although often perceived as a semi-rural residential area, Churston encompasses a mosaic of habitats that include ancient woodland, traditional hedgerow networks, pastureland, and coastal slopes.

Churston forms part of the English Riviera UNESCO Global Geopark, a designated landscape recognised for its exceptional geological heritage and the close interrelationship between geology, ecosystems, and human activity. Within this context, Churston contributes not only to the region’s geodiversity but also to the ecological networks that link coastal and inland environments across South Devon.

An Ecological Overview of Churston

Churston is characterised by a diverse mosaic of semi-natural and managed habitats that collectively support high ecological value. 

Woodland areas include ancient and younger woodland, providing structurally complex environments with layered canopies and understory vegetation that are important for a wide range of species. 

These woodlands are interlinked by dense hedgerow networks, functioning both as habitat in their own right and as ecological corridors.

Toward the coast, sloping land and coastal cliffs introduce additional microhabitats influenced by salt spray, wind exposure, and shallow soils, creating distinct plant communities and supporting coastal bird species.

Finally, Churston Cove supports a diverse underwater ecosystem shaped by its sheltered coastal position and the geological character of the South Devon coastline. 

The cove lies within the English Channel’s temperate marine zone, where relatively stable water temperatures and moderate tidal influence create favourable conditions for a range of marine habitats. 

Dense seagrass, sand, intertidal and rocky substrates dominate the seabed, providing structural complexity that supports varied biological communities.

The ecological value of Churston Cove’s underwater environment is closely connected to its terrestrial surroundings. Runoff from adjacent woodlands and grasslands influences nutrient inputs, while relatively low levels of industrial activity help maintain water quality. As part of the English Riviera UNESCO Global Geopark, the cove contributes to a broader marine - terrestrial ecological continuum, highlighting the importance of integrated coastal management to protect both underwater biodiversity and the resilience of nearshore marine habitats.

The Cirl Buntings, Bats and Hedgehogs

Churston supports a range of fauna that are recognised as protected or of conservation priority under UK legislation and biodiversity frameworks. 

The surrounding farmland, hedgerows, and scrub provide suitable habitat for the cirl bunting, a species listed as a priority under the UK Biodiversity Action Plan due to its historically severe population decline. 

South Devon represents one of the species’ last strongholds in the UK, making its continued presence in landscapes such as Churston of particular national importance.

Bat species are well represented across the area, reflecting the availability of mature woodland, linear hedgerows, and traditional buildings. In fact, all bat species in the UK are legally protected under the Wildlife and Countryside Act 1981 and the Conservation of Habitats and Species Regulations 2017.

Pollinators form a vital component of Churston’s ecological communities. Flower-rich hedgerows, grasslands, and woodlands support a wide range of bees, butterflies, moths, and hoverflies, many of which are included on national or regional priority lists due to population declines. These species provide essential ecosystem services, underpinning both wild plant reproduction and local agricultural productivity.

Finally, small mammals, including hedgehogs, utilise the connected network of woodlands, hedgerows, and green lanes for shelter and movement. The hedgehog is listed as a Species of Principal Importance in England, reflecting widespread declines linked to habitat fragmentation. 

The presence of these fauna highlights the role of Churston as a functioning ecological landscape and underscores the importance of continued habitat protection and sensitive land management to maintain compliance with UK conservation objectives.

Churston’s Soils

Soils are foundational to the ecological character of Churston’s semi-rural landscape, influencing both terrestrial and coastal biodiversity through their physical, chemical, and biological properties.

Across Devon, up to 1.5 kg of living organisms can be found in just one square metre of soil, including earthworms, insect larvae, mites, springtails, nematodes, bacteria, fungi, and archaea.

These soil organisms play essential roles in nutrient cycling, decomposition, and soil structure formation, directly influencing plant health and productivity as well as the abundance of invertebrates that provide food for birds, bats, and small mammals.

However, soil health is vulnerable to degradation through intensive agricultural practices, compaction from machinery or recreation, and chemical exposure. 

The integrity of soils across Churston’s woodlands, grasslands, and hedgerows therefore has direct implications for the condition of local biodiversity and the resilience of habitat networks.

Environmental Challenges

Unfortunately, Churston is subject to increasing pressures associated with suburban expansion and intensified land use. Residential development, as well as a growing tourism industry, lead to habitat disturbance and pose threats to the UNESCO Global Geopark.

One of the primary environmental challenges facing biodiversity in Churston is habitat fragmentation. The division of farmland and semi-natural habitats by infrastructure limits species movement and reduces genetic exchange, increasing the vulnerability of local populations.

Factors including habitat loss, pesticide use, reduced floral diversity, and climate variability have contributed to decreasing abundance and species richness.

The Grove Woods Revival Project

Grove Wood lies along the South Devon coastline close to the village of Churston Ferrers and is managed by the Torbay Coast and Countryside Trust. Situated within a narrow valley that slopes towards Churston Cove, the woodland supports a high level of biodiversity.

In 2017, a large area of the woodland was cleared when a significant number of Larch and Sweet Chestnut trees showed signs of a disease that can kill a range of tree and plant species, Phytophthora ramorum. Trees were felled on advice from The Forestry Commission. In response, local volunteers, organised as the Friends of Grove Woods, formed in 2018 with the aim of restoring this landscape.

“Since their work began, the woodland has shown signs of returning wildlife already. The large clearing, created following the mass tree felling, has become a new and extensive foraging area for bats including the greater horseshoe bat and several other species. Several butterfly surveys carried out last summer identified 20 butterfly species including the stunning white admiral and gorgeous silver-washed fritillary, already thriving in the newly created habitats.” [1]
