Описание
The Meetnetten - Transects for butterflies in Flanders, Belgium dataset is a sampling event dataset published by the Research Institute of Nature and Forest (INBO). It is part of the Meetnetten.be suite of monitoring networks for priority species in Flanders, in which data are collected at fixed locations using a standardized protocol (https://meetnetten.be). This dataset contains transect data for 8 priority butterfly species, as well as other butterflies observed during sampling. Here it is published as a standardized Darwin Core Archive and includes for each sampling event an eventID, date, location and sampling protocol (in the event core), the cloudiness, temperature, and wind force at the time of the event (in the measurement or fact extension) and for each occurrence an occurrenceID, the number of recorded individuals, status (present/absent) and scientific name (in the occurrence extension). Issues with the dataset can be reported at https://github.com/inbo/meetnetten-occurrences/issues
Generalized and/or withheld information: as these are sensitive priority species, location information is generalized to 1, 5 or 10 km Universal Transverse Mercator (UTM) grid cells. Original locations are available upon request.

Данные проекта
Meetnetten.be is a suite of monitoring networks through which the Flemish Government is collecting high-quality information on 65 priority plant and animal species. These are species on which Flanders has to report to Europe in the framework of the Habitats and Birds Directives, but also other species that are important for the Flemish nature policy.

Методы сбора
Sampling was done using the protocol described in Maes et al. (2019) and explained to volunteers in Ledegen et al. (2018). Cyaniris semiargus (mazarine blue / klaverblauwtje), Erynnis tages (dingy skipper / bruin dikkopje), Hesperia comma (silver-spotted skipper / kommavlinder), Melitaea cinxia (glanville fritillary / veldparelmoervlinder) and Pyrgus malvae (grizzled skipper / aardbeivlinder) occur in less than 30 locations in Flanders. For these species all locations are selected for monitoring and counted annually. Hipparchia semele (grayling / heivlinder), Lasiommata megera (wall brown / argusvlinder) and Pyronia tithonus (gatekeeper / oranje zandoogje) occur in more than 30 locations. For these species a random sample of 30 locations was drawn, which are counted once every three years. Within each selected location, transect counts are carried out. A fixed route of a maximum of 1000m is mapped out, along which the numbers of butterflies per section of 50 m are counted within an imaginary cage of 5 x 5 m around the observer. The sampling protocol may vary a little, depending on the butterfly species. 1. Cyaniris semiargus (mazarine blue / klaverblauwtje): the first generation flies in spring (May), the second generation can be found in high summer (10 July - 10 August). Both seasons are followed up in this monitoring network (at least three field visits per flying season). 2. Erynnis tages (dingy skipper / bruin dikkopje): flies in 2 generations, in spring (May) and in high summer (20 July - 20 August) and is therefore followed up in both seasons (at least six field visits). 3. Hesperia comma (silver-spotted skipper / kommavlinder): we ask at least 3 field visits in good butterfly weather, during the month of August. 4. Hipparchia semele (grayling / heivlinder): in a counting year we ask at least 3 field visits in good butterfly weather, in the period from 20 July to 20 August. 5. Lasiommata megera (wall brown / argusvlinder): in a counting year we ask for 6 field visits in good butterfly weather, 3 in May and 3 in the period from 20 July to 20 August. 6. Melitaea cinxia (glanville fritillary / veldparelmoervlinder): we ask at least 3 field visits in good butterfly weather, between 1 and 31 May. 7. Pyrgus malvae (grizzled skipper / aardbeivlinder): we ask at least 3 field visits in good butterfly weather, during the month of May. 8. Pyronia tithonus (gatekeeper / oranje zandoogje): in a counting year we ask at least 3 field visits in good butterfly weather, in the period from 15 July to 15 August. 9. Euphydryas aurinia (Marsh fritillary) : 3 visits a year in good butterfly weather (3 field visits in May)
| Охват исследования | 1. Cyaniris semiargus (mazarine blue / klaverblauwtje) was once widespread, but now endangered, with only one known location. It is bound to grasslands with sufficient Trifolium pratense (red clover), its host plant. 2. Erynnis tages (dingy skipper / bruin dikkopje) in Flanders is limited to a handful of locations in Limburg. It prefers (calcareous) grasslands with Lotus corniculatus (common bird's-foot trefoil). 3. Hesperia comma (silver-spotted skipper / kommavlinder) can be found in a limited number of dry heathland areas with well-developed heather-rich vegetation. 4. Hipparchia semele (grayling / heivlinder) is mainly found on dry heathland, heather-rich grasslands and dunes with open sand, sheep grass or ostrich grass. 5. Lasiommata megera (wall brown / argusvlinder) lives in verges and grasslands. Its populations have deteriorated considerably in recent decades. 6. Melitaea cinxia (glanville fritillary / veldparelmoervlinder) can be found in barren grasslands with a sufficient number of Plantago lanceolata (narrow plantain). 7. Pyrgus malvae (grizzled skipper / aardbeivlinder) can be found in only a handful of locations in Flanders. It lives on nutrient-poor grasslands, with Potentilla erecta (tormentil) as host plant. 8. Pyronia tithonus (gatekeeper / oranje zandoogje) is a common species in Flanders that occurs locally in high densities. The distribution of this species is limited to Europe and in Western Europe Pyronia tithonus reaches high densities, but here and there the species declines: therefore this butterfly was selected as a Flemish priority species. 9. Euphydryas aurinia (Marsh fritillary) The marsh fritillary (Euphydryas aurinia) is a butterfly of the family Nymphalidae. Commonly distributed in the Palearctic region, the marsh fritillary's common name derives from one of its several habitats, marshland. The prolonged larval stage lasts for approximately seven to eight months and includes a period of hibernation over the winter. |
