A species found only within a certain region is said to be
endemic species to that region. Endemic species are organisms that exist only in one geographic region. Some of the species are endemic to a particular continent or part of it others to a single island, but usually, that region is isolated in some way, so that species have difficulty spreading to other areas. It is also possible that the habitat of endemic species has unusual environmental characteristics to which endemic species are specifically adapted.

Maybe try moving the plants to somewhere else, or elevating the structure where the plants currently are
