Multidiciplinary assessment of BELgian wild BEE decline to adapt mitigation management policy (BELBEES) The present dataset includes all data about Belgian wild bees since the very beginning of the regional observations. It is comprehensive until 2018. It includes not only the numerous data issued from the digitization of collection material but also literature records and a huge number of validated data from citizen science networks. see project Data for more

Data Records

The data in this occurrence resource has been published as a Darwin Core Archive (DwC-A), which is a standardized format for sharing biodiversity data as a set of one or more data tables. The core data table contains 236,585 records.

This IPT archives the data and thus serves as the data repository. The data and resource metadata are available for download in the downloads section. The versions table lists other versions of the resource that have been made publicly available and allows tracking changes made to the resource over time.

Project Data

Recent researches show a general decline of pollinators in the world. With a long naturalist tradition, the dynamics of biodiversity in Belgium is one of the best known in the world. A previous analysis of the distribution of wild bees showed that out of 360 species, almost one third were already extinct or in regression. Since then, the situation is probably worse as in other countries. However, we lack detailed data to assess both the magnitude of the decline and the nature of the explanatory drivers involved. Now, environmental and economic issues related to pollination ecosystem service "pollination" become critical. Some restoration actions are launched at the federal and regional levels, but it is essential to clearly identify the causal factors and their combination in order to act properly. Several hypotheses are cited to explain the disappearance of pollinators: • climate change • changes in the structure of rural landscapes that increase the fragmentation and isolation of populations leading to loss of genetic diversity • increasing agricultural intensification and standardization of production processes eliminating food sources • the use of pesticides that may have direct and indirect effects on populations of pollinators • the development of diseases The general goals of the project are: 1) to collect and analyze data on recent changes in wild bee populations in Belgium, and 2) to assess the respective roles of different assumptions on the decline to identify field action combinations needed to restore pollination service in agro-ecosystems.
