This is a question that’s been raised a number of times before with regard to lichens, mangroves, moths, and more.
The upshot is that it’s not going to be implemented and that instead the way to do it is to make a project that filters for specific species, which has been done for lichens and mangroves at minimum, and probably for others too.
