Sites associated with data submitted in 2018/2019 and 2022/2023, and the networks belonging to each site, can be found in the relevant reports, as noted in the APIENs history page.
One of the aims of the 2025-2029 project is to establish a robust hierarchy to sites and plots within sites – currently submitted data do not differentiate plots, and their habitats, within sites, making it difficult to assess the extent to which different habitats are covered across pollutant gradients. We therefore anticipate providing further information on the sites, and the characteristics of habitats within plots at the sites, with the updated site and data submissions.
