From Seaweed to Sphagnum: Seven Autumn Citizen Science Projects in the South West

Autumn is not a quiet season for environmental monitoring. Storms move seaweed and plastic onto beaches, rivers run high, and moorland vegetation begins to die back, making some surveys easier and others more urgent. Across the South West, volunteer schemes are collecting data that conservation bodies, regulators and local groups use to track change. The seven projects below are practical ways to contribute, whether you have a free morning or a longer commitment.

Each scheme provides training, equipment or recording guidance. Check current dates, access arrangements and safety advice before setting out, and remember that citizen science works best when records are accurate, consistent and submitted promptly.

1. Seaweed and rocky-shore surveys, Cornwall

Cornwall Wildlife Trust’s Shoresearch programme trains volunteers to record seaweed species and abundance along rocky shores. Autumn is a useful window because some species are easier to identify after summer growth and before winter storms strip the shore.

Volunteers use quadrats, cameras and recording forms, often working in small groups with an experienced leader. Training sessions cover identification, survey methods and safety. The data help inform the management of marine protected areas and builds a picture of how shore communities are responding to changing sea temperatures and storm patterns.

2. Peat bog checks on Dartmoor

Dartmoor’s peatlands store carbon and slow water, but their condition varies widely. Volunteer monitoring organised through the national park and partner organisations involves checking dipwells, recording sphagnum cover, noting bare peat and mapping erosion.

Training and equipment are usually provided, and the work can be muddy and weather-dependent. The dataset matters because peatland restoration is costly and long-term. Reliable records of water levels and vegetation help show whether restoration is working and where further intervention is needed.

3. Riverfly monitoring across the region

The Riverfly Partnership’s Anglers’ Riverfly Monitoring Initiative is run locally by groups including the Westcountry Rivers Trust. Volunteers take kick samples from rivers and identify mayfly, stonefly and caddisfly larvae, which are sensitive to pollution.

A one-day training session covers sampling technique and identification. The data are used to flag possible pollution incidents and to build a long-term picture of river health. For anyone who walks the same stretch of river regularly, it is a structured way to notice change.

4. The Great Nurdle Hunt

Nurdles are small plastic pellets used in manufacturing, and they are often found on South West beaches after storms. Fidra’s Great Nurdle Hunt asks volunteers to survey a stretch of beach, count pellets and record the results through an app or online form.

No specialist kit is needed beyond gloves, a container and a willingness to look closely at the strandline. The data help map where pellet loss is occurring and support campaigns for better industrial handling. Autumn storms can strand fresh material, making it a useful time to record.

5. Hedgerow surveys

The People’s Trust for Endangered Species runs the Great British Hedgerow Survey, which asks volunteers to record hedgerow structure, species composition and berry abundance. Autumn is a good time to assess fruit and berry crops, which matter for birds and small mammals.

Guidance and a recording app are available, and no prior survey experience is needed. The data feed into advice on hedgerow management and help build a national picture of hedgerow condition. In a region where hedgerows define much of the farmed landscape, that evidence is valuable.

6. Tree health spotting

Observatree, led by Forest Research, trains volunteers to look for signs of tree pests and diseases and to report them through Tree Alert. Autumn is useful because some symptoms, such as lesions, dieback and fruiting bodies, become more visible as the growing season ends.

Online training and identification resources are provided. Early reports can help slow the spread of pests and diseases, and the records support national surveillance. Volunteers do not need to be tree experts, but they do need to follow reporting protocols carefully.

7. Freshwater quality with FreshWater Watch

Earthwatch Europe’s FreshWater Watch programme supports community groups to test local ponds, streams and rivers for nitrate, phosphate and turbidity. Kits are provided, and online training explains how to collect and upload results.

The data help local groups and catchment partnerships identify possible pollution sources and track changes over time. Autumn is a practical time to sample before winter flows make access difficult, although safety near water is paramount.

Before you start

Citizen science is not a substitute for professional monitoring, but it extends its reach. Choose a project that matches your time and experience, complete any training, respect land access and wildlife disturbance rules, and submit records even when they show nothing unusual. Absence of a species or a pollution incident is data too. With winter approaching, autumn 2026 offers a useful window to get involved before conditions close in.
