    Uittreksel

    Red Lists assess the extinction risk of species and are an important
    tool to prioritise species conservation and management measures.
    Worldwide, quantitative IUCN criteria are used to estimate the threat
    status of species at the regional level. In Flanders (north Belgium),
    about 70.000 distribution records of ladybirds were collected in 36%
    of all the grid cells (1 x 1 km²) since 1990 during a large-scale citizen-
    science project. Applying the IUCN criteria to the 36 resident
    ‘conspicuous’ ladybirds in Flanders resulted in two Regionally extinct
    species, three Endangered species and six Vulnerable species. A further
    seven species were considered Near threatened and the remaining
    15 species (39%) were assessed as Least concern. Three species were
    classified as Data deficient. Using the Red List status, we delineated
    ladybird hotspots which turn out to be located mainly in grid cells
    with large areas of Natura2000 sites. The ladybird dataset from Flanders
    provides evidence that IUCN Red List criteria can be applied to
    this charismatic, but relatively under-surveyed insect group. For calculating
    a distribution trend, we advocate the use of a high grid cell
    resolution (e.g., 1 x 1 km² or 5 x 5 km²). For estimating the geographic
    range, the use of extent of occurrence (EOO) instead of area of
    occupancy (AOO) is advisable when the survey coverage is relatively
    low. We discuss the opportunities of the availability of a ladybird Red
    List for regional conservation measures.
