The Information Center for the Environment (ICE),  under the leadership of Professor Emeritus Jim Quinn, developed the first version of this tool back in 2010.  ICE hosted the tool from 2010 to about 2017, when it needed to be taken down (for several reasons).  A "static" (non-database enabled) version of the old site can still be seen at cal-invasives.net.

ICE was an environmental information brokerage and research laboratory in the Department of Environmental Science & Policy at the University of California, Davis. ICE specialized in the development and dissemination of geospatial data and technologies; the development of robust data architectures dedicated to the cataloging of global environmental information; and the creation of decision support systems geared toward improving the capabilities of resource managers in a variety of sectors.
