NaturaList, a flexible app for creating taxonomic checklists

A new computer application (app) that creates interactive checklists is described. NaturaList is a progressive web app that is simple to implement, requiring only minimal skills in information technology from the developer, while also providing the possibility of an abundance of filter/search tools and links to other resources. The data are supplied in a simple spreadsheet. Once the resulting checklist is established on a webserver, it can be easily modified and updated. After implementation by the developer, it is initially accessed by the user online (looking like a standard webpage), after which it can function offline as a mobile app on any device (laptop, tablet, smartphone, etc.). Two floristic examples (from Vanuatu and Niue) are used to illustrate some of the features of NaturaList, but the app could just as easily be applied to any group of organisms, or to folk taxonomies, and allows for multilingual content.
