pollination and dispersal type; life cycle
length; economic impact; legal situation;
habitat invaded; hosts/habitat threatens;
impact; population status; habitat
(marine/freshwater); rating or ranking of
threats by region; spatial restriction; status
as an invader; invasiveness with respect to
climate; hosts; agricultural versus
environmental; and various combinations of
these.
Important Database Search Result Type
Respondents indicated that the most
important database search result type was
fact sheets/species profiles, followed by
species occurrence reports, distribution
maps, management and control information,
bibliographic information and references,
and current and past research (Table 2).

Responses in the Other category included
