Pins are Wikidata “endemic to” fields. Orange dots, when present, are GBIF occurrence tiles — survey bias included.
Breeding
Freshwater mussels bury in the bed and live for decades if the river still runs and the host fish still spawn.
In crisis
Even so, the populations in all river systems have declined significantly due to land use changes, development, and the construction of dams.
