Paul Dolman from UEA presented best practice and learning outcomes from the first BID-REX thematic workshop to the Natural England Science Advisory Board and discussed the use of biodiversity data with senior staff at Natural England, a local stakeholder. The presentation challenged the management of EU N2k SAC (Special Area of Conservation) habitats based on incomplete understanding of biodiversity requirements and presented a systematic approach to synthesising management requirements of multiple priority species to inform site management and definition of favourable condition.
