Biodiversity fauna and flora karting species KMhok

The biodiversity maps show the number of attention species, invasive species, karting species or Red List species that occur per area of approximately 1 square kilometre (0.75-1.25 km²). The areas are bounded by landscape ecologic features (previously a grid of square kilometre lofts was used). The maps thus give a good picture of the areas with the highest and lowest biodiversity in the province of Utrecht. There are both maps that represent the diversity of all flora and fauna groups together and maps of which the species number of each species group is shown separately. The data relate to validated observations stored in the National Flora and Fauna Database (NDFF), supplemented by accident-id observations collected by consultancy firms on behalf of the province. The data were included from the NDFF in February 2022. Less precise localised observations have been allocated to the area where their center is located. This also applies to observations at square kilometre level. Karting species are the less general or indicative plant and animal species that the province has been mapping since 1975 and 2005. The karting species are supplemented with breeding birds and the invasive species have been removed from the list. These are vascular plants, mosses, bees, bumblebees, butterflies, dragonflies, locusts, crickets, amphibians, reptiles, fish, mammals and breeding birds. The maps of the karting species cover the period from 2000 to 2021. So these are much more species than the attention and red list species.
