How many unknown (not yet described) species there are in world's biological collections?
I wish that I could use IUCN status; Threats, Management, ConservationStatus, Procedures, Distribution and Habitat chapters, and Maps to obtain the following data: Species' conservation status; current data requirements; location; estimate of species detectability in order to answer the following biological research question:
Which species of conservation concern could be most usefully targeted for student or citizen science research expeditions?
