Description

Invasive species - American bullfrog (Lithobates catesbeianus) in Flanders, Belgium is a species occurrence dataset published by the Research Institute for Nature and Forest (INBO). The dataset contains over 7,500 occurrences (25% of which are American bullfrogs) sampled between 2010 until now, in the months April to October. The data are compiled from different sources at the INBO, but most of the occurrences were collected through fieldwork for the EU co-funded Interreg project INVEXO (http://www.invexo.eu). In this project, research was conducted on different methods for the management of American bullfrog populations, an alien invasive species in Belgium. Captured bullfrogs were almost always removed from the environment and humanely killed, while the other occurrences are recorded bycatch, which were released upon catch (see bibliography for detailed descriptions of the methods). Therefore, caution is advised when using these data for trend analysis, distribution range calculation, or other. Issues with the dataset can be reported at https://github.com/inbo/data-publication/tree/master/datasets/invasive-bullfrog-occurrencesWe strongly believe an open attitude is essential for tackling the IAS problem (Groom et al. 2015). To allow anyone to use this dataset, we have released the data to the public domain under a Creative Commons Zero waiver (http://creativecommons.org/publicdomain/zero/1.0/). We would appreciate it however if you read and follow these norms for data use (http://www.inbo.be/en/norms-for-data-use) and provide a link to the original dataset (https://doi.org/10.15468/2hqkqn) whenever possible. If you use these data for a scientific paper, please cite the dataset following the applicable citation norms and/or consider us for co-authorship.

Couverture géographique

Flanders, Belgium. Most of the data originate from the province of Antwerp, as this province currently holds the main stronghold of the American bullfrog population.

Enveloppe géographique Sud Ouest [50,68, 2,54], Nord Est [51,51, 5,92]

Couverture taxonomique

The sampling focus for this dataset is American bullfrog (Lithobates catesbeianus (Shaw 1802) syn. Rana catesbeiana Shaw 1802), which represents 25% of the occurrences. The other occurrences are recorded bycatch (native amphibians, fish, non-native crayfish, invertebrates).

Méthodes déchantillonnage

Sampling occurs yearly between April and October. Most of the captures are made with paired fyke nets which are placed at the bottom of ponds and lakes for about 24 hours, but other methods are used as well (indicated in samplingProtocol). With each capture, the number of bullfrogs at each developmental stage is recorded (indicated in lifeStage), as well as bycatch species (native amphibians, fish, non-native crayfish, invertebrates) which were released upon catch. Also recorded are date, location, number of employees involved, and start and end time of the capture event. Captures are conducted for research purposes (management efficiency, determination of population density, etc.) and the active management of bullfrogs. All captured bullfrogs (tadpoles and adults) are humanely killed following international and regional regulation (see bibliography for methods), except for the ponds 13353 to 13362, 13371, and 13372, where the bullfrogs were released for research purposes concerning passive management by introducing native predatory fish. During the INVEXO project (2010 - 2012) those larvae were marked for capture recapture purposes. During the post-INVEXO project (2013) captured (sub)adult bullfrogs received an unique marking on their hind toe webs for the same reason, as well as to receive insight into their movement.
