Географический охват

In the initial stages, data from the simultaneous counts of summering geese were gathered at the level of the two westernmost provinces in Flanders (West Flanders, East Flanders), as these were considered in the Invexo and RINSE project's area. These are provincies with high numbers of summering geese, with several species under management (greater Canada goose, Egyptian goose, greylag goose). Here, a set of counting areas with confirmed presence of geese was selected and maintained as the sample study area over the years. Since 2014, management has been upscaled to other provinces. Therefore, counts are organised at the level of the whole Flanders region since.

Таксономический охват

All 20 species (and some subspecies and hybrids) in this dataset belong to the waterfowl family Anatidae. More than 80% of the occurrences are swans and true geese (subfamily Anserinae). Some individuals were not identified to species (e.g. unknown hybrids, eggs).

Методы сбора

This dataset contains data from several types of goose management as well as monitoring data. Management is performed with one of several methods: - Moult captures: during the moulting period (June-July), when the geese tend to congregate on open water, geese are trapped in large numbers with corral traps. - Larsson trap captures: for Egyptian goose (Alopochen aegyptiacus). The data are from a floating Larsson-like trap using a live decoy bird. Traps are checked daily for any caught specimens and bycatch. - Fertility reduction: the eggs are mostly pricked with a nail so the animal remains on the nest, sometimes eggs are shaken to destroy the embryo. Monitoring is performed using the following census method: - Simultaneous counts in summer (1st weekend after 15 July, a date which is set in accordance with the regions surrounding Flanders): multiple volunteers from bird working groups (Natuurpunt vzw) perform simultaneous count (within the same weekend) of a list of the more important goose sites (west and east flanders 2009-2013, Flanders since 2014). Counts are coordinated by the ngo Natuurpunt and a citizen science portal (http://waarnemingen.be/waarnemingen_projecten.php?project=231) is used for standardized data input and feedback to volunteers. Only when a site was completely surveyed for all of these species the observation was given the "Simultaneous count" - sample type. - Counts of geese at moulting sites (June 2012): during one day 8 teams of specialists visited every pond in the province of West-Flanders with a surface area of 5 hectares or more in search of groups of moulting geese. Also big streams where inventoried. - Field observations: These contain occurrences from 2 different sources: (1) counts carried out 3 days prior to or after the simultaneous counts weekend within the borders of any of the sites of intrest. These aren't necessarily completely surveyed for all species and should therefore be treated as loose, opportunistic observations, and (2) counts carried out during the simultaneous counts weekend within the borders of any of the sites of intrest but incompletely surveyed for all the species.

Описание этапа методики:

1. To allow reliable comparisons between years and areas, the counts are aimed for maximum standardization. Not all areas are counted every year. The aim is a yearly coverage of 65% of the areas. Trend calculations based on these census data therefore requires taking into account area and year effects.
