  "Description": "The TWN-list (Taxa Waterbeheer Nederland) is the Dutch\nstandard for naming taxons in Dutch Watermanagement. This\npackage makes it easier to use the TWN-list for ecological\nanalyses. It consists of two parts. First it makes the TWN-list\nitself available in R. Second, it has a few functions that make\nit easy to perform some basic and often recurring tasks for\nchecking and consulting taxonomic data from the TWN-list.",
