| 13 | Measure of habitat richness of Article 17 habitats using bird habitat density as a habitat richness proxy as defined in The European Urban Biodiversity Index (EUBI) | ||
| 14 | |||
| 15 | Habitat richness is a crucial component of biodiversity and habitat density describes how many bird habitats are encountered within a Functional Urban Area. This can be calculated using a count of Article 17 habitat types per hexagonal grid cell, derived from modified Article 17 dataset. | ||

| 44 | * Method taken from The European Urban Biodiversity Index (EUBI): “The process involves several steps to obtain the Article 17 habitat count per hexagonal cell. At first a hexagonal grid with a unique identifier for each grid cell is created. This grid is merged with UA polygons which have been assigned towards specific MAES habitats with a crosswalk using the GIS Tool “Union”. | ||
| 45 | * In a second step the Article 17 GIS- data is clipped to the FUA Boundary and also merged with the grid. Through this process the created datasets obtain a common identifier within the hexagonal grid, which is the basis for further processing steps. | ||
| 46 | * The data is imported into a database system (MS-SQL) for further processing and cleaning operation. | ||
| 47 | * Article 17 hex-grid data are assigned towards specific MAES habitats using the species-habitat linkages database. The data is then joined using the common identifier assigned within the hexagonal grid as well as the MAES habitat. This enables the filtering out of habitats which may cover a grid cell, but which are not assigned to a MAES habitat within the cell and thus are unlikely to occur at that location.” | ||
