Monitoring biodiversity at large spatial scales and over long periods of time is central to understanding how populations change, and supports conservation planning and the prioritisation of resources by decision-makers. While we have a good understanding of the monitoring frameworks that exist for some taxa, e.g. birds, such understanding is lacking for many others, including reptiles and amphibians.
This paper sets out to fill this knowledge gap for UK reptiles and amphibians, identifying existing sources of biodiversity data for these taxa and then characterising the nature of the data management network within which they sit. By using an approach known as network analysis, the team was able to visualise how the reptile and amphibian data were mobilised across the network, i.e. which were the key data sources within the network and how did data flow across the network? It also revealed valuable information on the species recorded and the degree of geographic and spatial coverage over time.
Forty-five sources of amphibian and reptile data were identified, which clustered into three main groupings: ‘recording projects’, ‘recording communities’ and ‘digital data platforms’. ‘Recording projects’ involve structured or semi-structured monitoring, the typical projects operated by BTO such as the reptile and amphibian component of BTO Garden BirdWatch. The network analysis revealed that the UK amphibian and reptile monitoring portfolio is dynamic and fragmented, with two data sources sitting outside of the network and many others receiving data but not then sharing this with other sources. While the network as a whole may provide comprehensive information across species and regions, the complexity of the network and the degree of fragmentation means that opportunities to leverage information where and when it is needed are not as good as they could be. If such shortcomings can be addressed then this would benefit reptile and amphibian conservation within the UK.
