Groom, G.B., Bladt, J., Moeslund, J.E. & Ejrnæs, R. 2018. Developing biodiversity proxies. Technical description. Aarhus University, DCE – Danish Centre for Environment and Energy, 42 pp. Technical Report No. 123. http://dce2.au.dk/pub/TR123.pdf
In 2014, Aarhus University and Copenhagen University in collaboration developed a biodiversity map for the Danish Nature Agency (Ejrnæs et al 2014). The map consists of two parts: 1) a national prioritisation of nature areas based on a complementarity analysis of species at 10×10 km scale and 2) a local prioritisation of nature areas based on a bioscore calculated as 10×10m pixels. Calculation of the bioscore is partly based on proxies for biodiversity. This report describes the methods developed and applied for the production of national datasets of certain new proxies for testing for potential use in the Biodiversity Map. The new proxies covered in this report take their basis in a mix of airborne laser survey data products, aerial orthophoto image data and certain national geoinformation data layers. The results of the testing of the new proxies for use in the Biodiversity Map are reported in the parallel report to this report, Ejrnæs et al. (2018).
