The quick answer is no, but I will attempt to respond to your question.
There are models in other areas. For example, there's something called the Avian Knowledge Network. It's people who keep information on birds. There are many different systems that are keeping that information.
I think that it would be a mistake to strive toward one consolidated database of information. It's more about recognizing that these systems exist. They're being created for perfectly valid reasons, and they're serving the interests of the organizations that have created the databases.
It's about, then, how we actually create a system that can access that information wherever it's found, whether it's EDDMapS, whether it's iNaturalist. There are a number of systems even in Canada that have that information. It requires an approach that is more along the lines of what I characterize as a knowledge network: these different data holders' developing their systems such that the information can be accessed and rolled up to enable, for example, improved risk assessments. This is something that we're not really able to do in Canada because we can't access information and know where all the species are. We have it, but there's some information here, some there and some in other locations.
