The Taxa Watermanagement the Netherlands (TWN) checklist consists of several lists of species that are relevant for the proper management of Dutch inland water bodies. The lists contain aquatic, semi-aquatic as well as terrestrial organisms. Nomenclature of the taxa is consequent binominal with references to authors and identification literature. At a regular base the lists are being updated and improved by specialists from the Rijkswaterstaat laboratories. The lists are part of the official Aquo-standard, used by all Dutch water managing organisations. The TWN checklist accommodates over 16.000 species and is sub-divided in lists on amphibians, birds, butterflies, diatoms, macroalgae, macroinvertebrates, mammals, macrophytes, nematodes, phytoplankton, reptiles and zooplankton.
The data in this checklist 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 22,241 records.
1 extension data tables also exist. An extension record supplies extra information about a core record. The number of records in each extension data table is illustrated below.
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.
The table below shows only published versions of the resource that are publicly accessible.
