Using citizen science to monitor peatlands

Phenology is the study of the timing and seasonal changes in a plant's life cycle events, specifically when plants bud, grow green leaves, flower and fruit, as well as when their leaves turn brown and shed. Studying the ‘greenness’ of plants is important, as this can be linked to how well the ecosystem is functioning and whether it is a carbon sink or not.
This project aims to monitor changes in peatland green leaf phenology (how the peatlands change colour over the course of the year) using smartphone photography. Members of the public (citizen scientists) will be able to take fixed-point photographs using specially designed phone cradles at a wide range of wetland project sites. Analysis of the photos will then give us an indication of the health of these important wetland ecosystems and their resilience to disturbance.

We can use smartphone RGB photos to understand how these plants 'green up' over the summer, the timing of when they hit their maximum greenness and how they start to turn brown in the autumn. The photos will be used to analyse the change in growth over the growing season.

Project update

Tracking the Colour of Peatlands phone cradle sites dotted across a world map.
The initial phase of this project focused on three main sites – the Boreal Wetland Centre, in Alberta, Canada; RSPB Forsinard Flows, in Scotland; and the Eden Project, in Cornwall, UK.

Following the successful completion of phase one, this initiative has now expanded to 16 new sites, with phone cradles and signage sent out to additional sites in Canada and the UK, as well as sites in Australia, Finland, Ireland, Germany, France and Sweden. Dr Scott Davidson hopes that this work can help to raise awareness of the importance of wetland and peatland conservation and help to ensure increased protection, restoration and management for these environments so that they can continue to offer viable nature-based solutions to climate change.

Peatlands are nature's unsung climate warriors

Peatlands are among the most critical ecosystems on earth. It is surprising, then, that despite public support, many environmental protections for peatland have failed to materialise. From peat cutting and burning to the continuing sale of peat-based compost, these habitats are under threat. Has their public image led to them being misunderstood and underappreciated?

Plymouth Peatlands Research Group

Investigating the link between historic and current land-use change, climate change and disturbance, our peatland research falls into the thematic areas of peatland ecosystem services, restoration practice, and impacts of disturbance regimes on peatland function. We work with key stakeholders to drive positive change in restoration, monitoring and management, and provide specialist advice and input into planning for the integration of cultural services within peatlands and forested wetlands.
