Assessing state and trends in biodiversity from monitoring data
Key issues in assessing state & trends of biodiversity
What kind of issues are covered?
Power analysis (or the risk of incorrectly concluding there is no trend)
What's the point about detectability - what is it and why is it important?
What to do if data points are missing in a time series?
Estimating range changes
Estimating abundance trends from mapping data
Estimating abundance/population changes from monitoring data
Main European habitat classifications
Classification of habitat types and delimitation of patches
Quantification of various habitat properties and estimation of change in such properties
Basic data, estimates & trends: How can inferences be made by combination of raw data, estimates, and trend information?
Combining data or estimates for distribution or abundance for species, based on presence/absence, counts, or CMR data
Combining indices of distribution or abundance for species, based on presence/absence or counts data
Meta-analysis
Transforming habitat typologies to same classification
Combining RS and mapping data
Producing maps from complete coverage data
Deriving spatial properties from maps or spatial data
Inferring causes of change
Potential and limits of causal inferences from monitoring data
Additional policy assessments
Assessing changes in threat status
Assessing favourable conservation status
