Terrestrial Surveillance Development and Analysis (TSDA)

The Terrestrial Surveillance Development and Analysis (TSDA) project is a partnership between JNCC, the UK Centre For Ecology & Hydrology (UKCEH) and the British Trust for Ornithology (BTO). The project aims to develop and enhance volunteer recording schemes and use of their data to address policy-relevant questions about biodiversity. The work is science-driven and seeks to serve the needs of UK governments, Country-level Nature Conservation Bodies (CNCBs, including Natural England, NatureScot, Natural Resources Wales and DAERA) and volunteer recording schemes (represented by JNCC’s Terrestrial Evidence Partnership of Partnerships: TEPoP). The partnership was established in 2017, with the first phase running until 2022, with a summary of the outputs captured below. The TSDA partnership is now developing a vision and strategy to guide work over the next 5 years until 2027.

TSDA Outputs 2017-2022

At the start of the project, a needs assessment was completed to identify the biodiversity needs of the UK’s CNCBs.

A priority need was for wider spatial and taxonomic coverage of recording schemes, so TSDA sought to understand the limitations of data and the impacts of a lack of representativeness. TSDA undertook work to collaboratively define the meaning of ‘ecosystem health’, going beyond species to assess change in ecological community metrics.

TSDA considered the use of new technology, specifically acoustic monitoring, and how this can contribute to policy needs, how new acoustic monitoring schemes (e.g., British Bats Survey: BBatS) can be designed, and how this could support cross-taxon monitoring (e.g., small mammals and insects).

TSDA provided practical advice to develop better data products that are more consistent and “FAIR” (findable, accessible, interoperable and reusable).

New statistical methodology was investigated including ‘integrated distribution modelling’ (IDM). This approach allows different types of data (such as from structured and unstructured recording schemes) to be rigorously combined in single analyses. A ‘user guide’ was developed drawing on research conducted in TSDA showing the benefits of IDMs.

TSDA researched ways of supporting volunteer engagement and retention. A trial was started to target revisits to under-recorded locations, and the project scoped methods for effort recording and habitat recording to complement earth observation data.

Multiple datasets were used to assess the impacts of pressures, including invasive species and pollution, and to assess the value of protected areas.

Predictive analyses are valuable to assess the impact of medium-term future scenarios. TSDA brought together information on the latest tools and applied this to potential changes in urban habitats.
