Abstract

Meetnetten.be - Sightings for Ephippiger ephippiger in Flanders, Belgium 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 counts of the Saddle-backed Bush Cricket Ephippiger ephippiger in Flanders. Here it is published as a standardized Darwin Core Archive and includes for each sampling event an event ID, date, location, sampling effort and sampling protocol (in the event core) and for each occurrence and occurrence ID, the number of recorded individuals, status (present/absent), life stage 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.
We have released this dataset to the public domain under a Creative Commons Zero waiver. We would appreciate it if you follow the INBO norms for data use (https://www.inbo.be/en/norms-data-use) when using the data. If you have any questions regarding this dataset, don't hesitate to contact us via the contact information provided in the metadata or via opendata@inbo.be.

Project details

Project title: Meetnetten.be
Personnel: Frederic Piesschaert
Funding: Flemish Government
Study area descriptions/descriptor: Flanders, Belgium
Design description: Each monitoring network consists of fixed sample locations in which the target species is counted based on a standardized protocol. Data collection relies mainly on specialized volunteers, coordinated by the NGO Natuurpunt Studie. Fieldwork is planned and monitored with the web tool https://meetnetten.be, which is also used for entering the collected data.

Methods

Method step description: 
- . 	Researchers from INBO and Natuurpunt Studie define and document the appropriate sampling protocol for the target species.
- . 	Fieldwork is planned and coordinated by Natuurpunt Studie, using https://meetnetten.be.
- . 	Data are collected in the field by specialized volunteers, using the predefined sampling protocol.
- . 	Volunteers enter the collected data in https://meetnetten.be.
- . 	A custom SQL view is created in the meetnetten.be database to map the original data to Darwin Core as an event core, occurrence extension and measurement or fact extension.
- . 	The Darwin Core views are connected to the INBO IPT and documented with metadata.
- . 	The dataset is published and registered with GBIF.
Study extent description: The question we are trying to answer with the grasshopper monitoring network is whether the species in Flanders over a 24-year period is decreasing by at least 25% or increasing by 33% (Westra et al.2014). Since the 2 species  (Stenobothrus stigmaticus and Ephippiger ephippiger) of monitored grasshoppers occur at less than 30 sites, all sites are monitored completely. 
Zadelsprinkhaan - Ephippiger ephippiger - The Saddle-backed Bush Cricket is a very remarkable and large bush cricket with a saddle-shaped neck shield and strongly reduced anterior wings. In Flanders, this species only occurs in very open wooded heathland in the province of Limburg.
Sampling description: Sampling was done using the protocol described in De Knijf et al. (2016).
We monitor Ephippiger ephippiger by counting calling males along a fixed trail. Each of the 5 marked areas are counted twice in the most active period (25 August to 15 September).
Quality control description: All data is validated
