1. No effect of Nitrogen?
Something wrong?
Not exceeded sites?
Non-sensitive habitats
Metrics?

2. Species number doesn’t tell the story Rob Maas: easy
Site Level
Species number doesn’t tell the story
Rob Maas: easy
UK: species no. didn’t relate to good habitat quality
DK: increase in negatively effected heathland
CBD: not a selected policy indicator for biodiversity
Shannon, Simpson
Several: complicated
Respond different to biodiversity loss
CBD: not a selected policy indicator
Other options: Selection of species
DK, CH, .. : oligotrophic species
UK, NL: positive indicators for habitat quality
Regional level: 251 habitat types in Europe
Jane: number of effected habitat types
DK: number of protected areas

4. Biodiversity endpoint based on policy targets
High quality (favourable status)
Low quality
Characteristic species ≠ positive species
List of target (typical) species or
List characteristic species
List of species
at high
Habitat quality
- List of competing species

5. Calculating Endpoint PROPS for 80% species Chance of occurrence
Maximum chance
Suitability =
Overall Suitability for high quality =
Averaged over species
Suitability/ maximum suitability (maximum in history/future)
