The opportunities for semi-structured and effort recording to enhance the value of biological recording by volunteers 2022
Biological recording is essential for monitoring changes in the distribution and abundance of species. To effectively use any collected information for monitoring purposes, there are five core principles of biological recording schemes: representative sampling locations; an adequate sample size; sufficient detection of the target species; recording a representative sample of species present (or all species); and a long-term sampling strategy that enables valid inference of change.
Citizen science is increasingly seen by researchers and policy-makers as a cost-effective method of gathering biological records, and can make substantial contributions to biological recording through the voluntary collection of species occurrence data for recording schemes. Voluntary engagement in environmental monitoring encompasses a spectrum from ‘mass participation’ to ‘scientific sampling’, which can alternatively be described as the variation between ‘opportunistic’ or ‘unstructured’ recording towards more ‘structured’ recording. Structured and unstructured recording each have advantages, but they also have disadvantages. In particular, structured recording typically requires high levels of commitment from volunteers and is therefore limited in how many locations and taxa can be included, whereas data from unstructured recording can cover a much wider range of taxa and locations but can be challenging to analyse.
In this report, we explore the use of recording approaches that lie between the two extremes of the spectrum, and consider how these approaches are beneficial for biological recording, if they are feasible for volunteers, and how they could be implemented by recording schemes or organisations in the UK.
