2012-14 Call for Data results

Final goal: Derive a harmonized metric from these submitted variables and indicators with the objective to quantify “no net loss of biodiversity” on a regional scale.

… then normalized by the CCE to express “no net loss of biodiversity” (NNLB) for each EUNIS class in a country.

If countries select a biodiversity index for their sites, they should also select their limit.How to compare in case of large bordering differences?

Conclusions

- 9 countries participated in the call for data- 7 did Dynamic Modelling for sites

- No obvious relation between nitrogen deposition and biodiversity indices using vegetation modelling so far

Recommendations(and/or part of the training session issues

- We need to apply indices based on species occurrence probabilities in stead of abundance… or model abundances

- “preferential” or “typical” species need to be selected by NFCs (vegetation units now in props…)

- NFC calculation(steps) should ultimately focus on a regional scale (compare eg. Targetloads)

- Please, mind the tables, naming and units in the call!!- We should return to annual responses

- We should have an intermediate milestone with a 2 years call
