ODONAT Grand Est network created a sensitivity map for the Lesser Horseshoe Bat (Rhinolophus hipposideros) in 2018-2019. The map represents species distribution from recent occurrence data (1999-2018 or 2009-2018) on a 10x10 km Lambert 93 grid. The layer is described as non-exhaustive and represents the state of knowledge at the time of its creation.
Use Cases
- Modeling species habitat suitability based on recent occurrence data.
- Assessing conservation priority areas based on the 10x10 km grid cells.
- Analyzing changes in bat distribution over the 1999-2018 time period.
- Planning environmental impact assessments using non-exhaustive presence data.
Strengths
- Data is based on recent occurrence records spanning up to 20 years (1999-2018).
- Spatial data is structured on a standardized 10x10 km Lambert 93 grid.
- The map explicitly includes both established populations and erratic individual observations.
Limitations
- The map is explicitly described as non-exhaustive and represents only the state of knowledge at its creation.
- Description metadata is limited; actual data quality requires manual inspection after download.
